The 8 Best Bench Grinders For Sharpening And Grinding
Be it for removing rust, sharpening the blade, cutting metal or smoothing the rough edges, bench grinder is a must-have tool for professionals and DIY’ers.
They are like a spinning grindstone and available in different wheel sizes (6-inch and 8-inch) with different power ratings.
Though they are simple tools, bench grinders have to be purchased with careful consideration. With so many options, it is can be tough choice to settle down with a choice.
If you are experiencing the same, we recommend checking out the main factors mentioned here.
Wheel Size: Different bench grinders differ from each other in terms of their wheel size (diameter of the grinding wheel). A 6-inch and 8-inch are two common wheel sizes available for bench grinders, in which 6-inch is designed for DIYers to sharpen, clean, polish and repair gears and tools. 8-inch is meant for professionals for complicated grinding tasks. 8-inch is a bit expensive, yet slower than the 6-inch model.
Motor Power: The inside motor of a grinder will affect its overall performance. The higher the motor power rating, the better and faster the machine will perform.
- A grinder with ½ or ¾ HP is required to perform low-intensity jobs, while a grinder with a 1 HP motor is essential to do heavy-duty projects.
- A 6-inch grinder has a motor with ¼ HP (around 2.1 amps power), whereas an 8-inch grinder has ¾ HP (around 5 amps power).
Speed: It is measured in terms of revolutions per minute (RPM), which depends mainly on the motor power. For cutting hardened steel or stronger metals, you need a grinder having a faster speed wheel with 3000 RPM, while for working with wood, you will require a slow speed grinder with 1750 RPM. Choose it wisely as per your work requirement.
For more information and detail specifications, we recommend you to read our “Buying Guide”. Using the same information, we are here with a list of some top-notch bench grinders after thorough analysis. Read on to know how to choose your best bench grinder as per your requirement.

What to Consider Before Buying a Bench Grinder:
One has to choose the best bench grinder based on their type of grinding, sharpening, polishing or cleaning task. If not sure about what features to look for while shopping for a bench grinder. Here are the factors that have to be taken into account when purchasing a bench grinder.
Bench grinders are used widely to grind away rust from steel or sharpen a blade, which makes it the most essential tool in the auto-mechanic workshops, DIYers, woodworking craftsperson or others using lots of hand tools. They come in various types and a few most commonly used types are mentioned below.
Automotive workers (both mechanics and auto-body workers) use the bench grinder on regular basis for removing rust from bolts and nuts and for polishing chrome engine, steel, and body parts. However, a bench grinder built for the automotive industry will feature quick spinning speeds of up to 3450 RPM. Cleaning and polishing auto parts on a bench grinder will save a lot of time and effort over done manually (by hand).
Usually, craftsmen and woodworkers rely on sharp hand tools like chisels and planes to create well-fitting dovetail joints and to smoothen the rough wood. Bench grinders made for woodworkers have a slower spin speed compared to the above automotive ones. Here the tempered steel in hand tools gets damaged due to high heat resulting from fast-spinning grinding wheels. Go with a grinder having a slower spin of 1725 RPM wheel to sharpen tempered tools.
Variable Speed –
Choose a variable speed bench grinder when you want to dabble both woodworking and car/auto-body repair. This grinder will let you operate the tool at its highest speed when cleaning car bolts and nuts, while still, it let you reduce the speed to sharpen hand tools like chisels. Though is a bit expensive than single-speed counterparts, yet it is worth rather than buying two separate grinders for low and high speeds.
Generally, standard bench grinders are heavier, which weighs up to 50 pounds and they perform well when mounted to a workbench to prevent its movement. While looking to carry a grinder along with you to various worksites, then purchase a small, lighter grinder (about 10 pounds) featuring rubber feet to prevent sliding when positioned on a worktable.
The wheels are made of different types of materials that include silicon carbide, aluminum oxide, wire wheels, ceramic aluminum oxide, and buffing wheels. However, the type of material used for its construction will let you know the tool’s performance.
Mostly, bench grinder wheels (exclude buffer wire wheels) will have one of these two grits – 36 grit (for aggressive grinding) and 60-grit (for finer grinding). Let’s get into its details.
Silicon Carbide –
It is a common type of grinding wheel suitable for a wide range of grinding tasks like sharpening cast iron and lawnmower blades. With its quickly heat up nature, they may ruin the temper in high-quality woodworking tools, such as hand planes and chisels.
Aluminum Oxide –
Since they won’t heat up as faster as silicon carbide wheels, they are specially designed to grind hard metals like alloy steel or carbon steel, which we found commonly in hand tools.
Wire Wheels –
This type of wheel is made of brass and steel bristles, which makes it quite useful for faster cleanup of gunk and grease from auto valves and fittings. You can absolutely see this type of wheel mostly in a mechanic shop for automotive repairs and body work.
Ceramic Aluminum Oxide –
It is an abrasive wheel that is mainly used to grind away material from steel and other hard alloys. For instance, you can use this wheel while grinding off half of an axe head.
Buffing Wheels –
Since it is made with a variety of thick, brushed fabrics, they are meant for polishing steel or other metal items to offer a high shine. They are mostly used by auto-body workers to accomplish high shines on chrome automobile features like hubcaps while restoring a car.
Generally, these bench grinders are labeled by their wheel size, and this size is the diameter of the grinding wheel used by the bench grinder. The most common sizes are 6-inches or 8-inches in diameter. Even though both these sizes will perform in the same way, yet with small differences. Check which one suits best for your requirement.
|Parameters||6-Inch Grinder||8-Inch Grinder|
|Best Option For||DIYers||Professional Mechanics or Woodworkers|
|Motor Speed||3400 – 3600 RPM||1500 – 2000 RPM|
|Suitable For||Grinding off grime, paint or rust, Sharpening knives tools, Sanding metal or wood, Light – moderate repairs||Automotive, Metalworking, Woodworking, and DIYs.|
|Price Range||65 – 175 (less expensive)||100 – 500 (or more).|
|Weight||10 – 25 pounds||20 – 50 Pounds|
|Speed Settings||Low or High Speeds||Low or High Speed|
|Portability||Portable tool or mount to a workbench||Must bolted to a worktable|
Note – You can also find a 3-inch smaller bench grinder, which is mainly used for crafts or other detailed works.
A motor is a crucial part of any power tool, including the bench grinder. It determines the device’s working and thereby affects its overall performance. Its power rating is measured in terms of horsepower (HP). However, if you pick a grinder with a larger and powerful motor, then it can spin larger wheels at high speeds and thereby make it a perfect option to use for a variety of tasks/jobs.
For low-intensity jobs, make sure to use a grinder with motor power of ½ or ¾ HP. For heavy-duty tasks, pick a grinder with a motor power of 1HP.
The motor power as per the wheel size is as follows – For 6-inch grinders should come with motors around 2.1 amps of power, which is approximately ¼ HP. While 8-inch grinders can go with motors around 5-amps of power, which is approximately 3/4 HP.
A bench grinder with 1HP motor power is considered the most powerful, yet they are used mostly in professional or industrial settings but not for DIY projects.
Though the speed of a grinder will rely on the horsepower of the motor, and it is measured in terms of revolutions per minute (RPM).
A grinder wheel with a minimum speed of 3000 RPM will spin at a faster rate that let you cut through stronger metals and hardened steel. While choosing a grinder with a speed of at least 1750 RPM (slow speed) to cut through wood, mostly softer woods.
Few models feature dual speed settings that let you choose a minimum RPM to a maximum RPM. Some models let you customize the speed within its range with its variable speed options. It is a flexible option that allows for a wide range of project applications.
Usually, there are 3 main grit abrasive wheel sizes – 30, 60, and 100. However, the coarse 30-grit wheels are ideal for general sharpening, yet if looking for smooth and accurate output, then go with fine wheels of 60 or 100 grits.
Choose a coarser 30-grit wheel to sharpen or grind tougher materials, while going with a less coarse 60 or 100 grit grinding wheel for softer materials. So, always pick the right type of wheel as per your project requirement.
The size of the grinder will determine how powerful it is and what work it lets you do with the grinder. Small-size bench grinders are constructed for low-intensity grinding, shaping or sharpening metal. Alternatively, larger bench grinders are ideal to use for cutting, grinding, or sharpening larger tools and objects.
Ensure to check the size and form factor of the bench grinder and also go through its detailed description to know for what jobs it suits to perform well before buying. A bench grinder with a smaller grinding wheel (or single grinding wheel) is small and compact that takes less space on the bench.
There is a risk factor involved in operating all power tools (not excluding bench grinders). For instance, grinding iron will create sparks and send shards of metal flying. This makes it essential to wear safety glasses while using a grinder. Usually, these bench grinders have some safety features that reduce the risk, yet they won’t eliminate the overall risk associated with their operation.
Here are some of the safety features to be followed for the safe and effective operating of grinders.
Eye Shields –
One can find these transparent plastic covers above the opening through which the grinding wheel touches the workpiece. It prevents any scraps from flying off and hurting the eyes. Upon regular usage, these eye guards get scratched or dirty, which means you have to replace them with a new one.
Spark Arrestors –
These are small steel plates that are placed between the eye guards and wheels. They are intended to avoid sparks from flying all over the workshop. There still have sparks, which means you have to keep flammables at a distance of few feet away from a bench grinder when using them. However, the spark arrestors keep the sparks from flying too far.
Dust Exhaustion –
One has to use dust exhaustion systems, ports or vents to get rid of dust and debris that forms during the grinding process and if inhaled may harm your health. Also, it maintains visibility that let you see you working with the grinder.
If your grinder is a wet grinding machine, which comes with built-in cooling systems to keep the machine cool. Or else, if the grinder is not a wet grinding machine, then you need to use a pot or bucket of water to dip the workpiece in it to deter the machine from overheating.
The wheel’s color will let you identify the type of job you can do with the grinder. Here are some suggestions you have to follow for doing perfect work.
- Brown wheels are perfect for heavy fettling and trimming.
- White ones are suitable for sharpening
- Grey ones are ideal for every day grinding.
- Green ones are for fine grinding and they work well with blades and drill bit or anything made from silicon carbide (like carbide tools).
Most of these bench grinders are directly mounted to a pedestal stand or bolted to a worktable surface. However, a model mounted on a separate stand is quite beneficial, why because it won’t take up any worktop space.
When it comes to portability, this bench grinder won’t offer lots of flexibility and the workpiece has to be carried to it. While looking for a portable, handheld option, you have to choose an angle grinder.
Wheel RPM Rating:
The maximum RPM rating of the wheels are given on a label, and for a safe and effective operation, the RPM of the grinder should match with this value. Also, you may find a tag with a note that states the maximum operating speeds that specified on the wheel’s label should not be exceeded. However, over-speeding the grinding wheel will result in it to explode.
Durability and Warranty:
The durability and reliability of a bench grinder will ensure its longevity, and to know its durability, you have to look at its build quality. A grinder using cast iron for its base is highly stable and sturdy. Also, check the warranty duration offered by the manufacturer on their products. While most options out there come with a 1-year or 2-year warranty, some are reliable and durable options that offer a 5-year long warranty that lasts easily for a long time.
There are some add-on features that are specially designed to make the grinder use with ease. Here are some of the common accessories that you have to check while purchasing the grinder.
- LED lights in a grinder will illuminate the work area for a clear and better vision of the workpiece and what you are working on.
- Tool rests, where the operator can brace a blade or knife to keep it steady when grinding. It is a common accessory found in all bench grinders.
- A water tray near the grinder’s bottom to dip a chisel (or other items) after grinding will cool it off.
- Rubber feet (especially on portable models) will prevent the grinder from sliding across a worktable while operating a grinder.
How to Use a Bench Grinder?
One can easily gain expertise or skill on its usage with a bit of practice. All you need is steady hands and precision to make it use correctly. Or else, you may sharpen the tools in the wrong way or make oddly or uneven shaped workpieces. Ensure to wear proper work gear like safety goggles or gloves before starting a bench grinder.
It is essential to know the type of wheel you need to use for your task. Usually, wheels vary in coarseness levels, which makes them suitable for various applications. After determining the required wheel, you need to turn on the bench grinder and wait till it starts rotating at its maximum speed.
Then pick an item or object you are looking to grind by getting in contact with the spinning wheel. Ensure to maintain at an acute angle to the wheel – 25° or 30°. Initially, avoid pushing or bringing the object too close to the wheel. Now move the object slowly towards the wheel, so that you won’t end up overdoing it.
While grinding the metal, the grinder tends to get hot in the process, and this heat might damage the tool or object, which is quite essential for proper usage of the bench grinder. So, you have to keep a pot or bowl of water handy to stop the grinding often and dip the tool into water.
If dealing with small objects, make sure to use pliers to hold them to prevent fingers from getting close to the spinning wheel. Also, it is a bit difficult to handle small objects while wearing work gloves. So, prefer to use pliers for a better grip over those small objects/items.
While sharpening the tool’s blunt edge, the sparks will fly downwards. Alternatively, the sparks will fly upwards when the tool gets sharp enough.
Mounting Tips of a Bench Grinder:
If there is a space available on the workbench, most people like to mount a new bench grinder to keep them stable when smoothing or sharpening the parts and tools. Generally, bench grinders are heavier, which means bolting them to worktable within the holes given in their base is ideal.
Here are some tips that let you know how to mount a bench grinder properly.
- Locate the bench grinder where you want to place it on the workbench.
- Mark all the four base holes of the grinder on the workbench by using a pencil.
- Then use a drill machine to drill through those pencil marks.
- Insert bolts via its base holes, and you drilled holes in the workbench to attach the bench grinder. Finally, secure the bolts in place with provided nuts.

What to Look for in a Bench Grinder
There are two common sizes of bench grinders: 6-inch and 8-inch. That number refers to the size of the grinding wheel. You’ll also find smaller bench grinders—3 inches is fairly common—that are used primarily for crafts or other detailed work.
For the average DIYer, a 6-inch bench grinder is the right choice. These tools typically spin the grinding wheels at a set speed of anywhere from 3,400 to 3,600 revolutions per minute, and they are excellent for sharpening knives and tools, grinding away rust, paint, or grime, sanding metal and wood, and other light-to-moderate repairs around the house or garage.
Eight-inch bench grinders are standard in automotive, woodworking, or metalworking shops, but some DIYers like them for home use, as well, particularly if they do a lot of work with metal. The wheels typically spin more slowly on these larger grinders—around 1,500 to 2,000 is a common range. Some have both a high and a low speed setting, so you can choose the one that best suits your needs—slower for more control, faster when you don’t need as much finesse.
Most bench grinders come with two installed wheels, and usually, those wheels will have different grits and be different types. Commonly, one wheel will have a grit size between 80 and 120 for handling light grinding tasks, and the other will be either a medium grit of 30 to 60 or a coarse grit of 20 to 24 for more aggressive work.
The most common wheel materials are:
- Silicon carbide: This common material is suitable for most grinding and sharpening tasks, but tends to heat up very quickly.
- Aluminum oxide: Another common material that’s especially suited to sharpening and grinding hard metals. Aluminum oxide doesn’t heat up as quickly as silicon carbide.
- Ceramic aluminum oxide: Excellent for a wide range of metals, ceramic aluminum oxide is long lasting, self-sharpening and not prone to overheating.
- Wire: These wheels are covered in steel or brass wire filaments. They’re used mostly for automotive repairs and bodywork, but if you do a lot of work with metal, this might be a useful choice.
- Buffing: These heavy cloth wheels are perfect for polishing, buffing, or shining up a wide variety of metals.
You’ll find that some manufacturers state the power of their bench grinders in amps, while others use horsepower. As a general rule, 6-inch grinders have motors with around 2.1 amps of power—that’s around 1/4-horsepower. Most 8-inch grinders have around 5 amps of power, which is roughly 3/4 horsepower.
The most powerful bench grinders boast 1-horsepower motors, but these are generally used in industrial or professional settings, not for typical DIY projects.
While not a must-have tool for every DIYer, a bench grinder is more versatile than you might think. Along with its major use of grinding down metal, you can also use a bench grinder to sharpen tools, buff or polish metal, remove hardened dirt or other grunge from tools, cut metal or wood, remove rust, smooth and shape the edges of wood or metal, and even work on crafts such as jewelry-making, model-building, or reviving rusted metal items.
Just about every bench grinder has two wheels, which serves to increase the versatility of the tool. Typically, bench grinders come with one sanding/grinding wheel with a light-to-medium grit for light sanding tasks and one sanding/grinding wheel with a medium-to-coarse grit for tougher grinding situations. But there are many wheels available for these tools, some quite specialized. You can swap out one or both of the wheels for a finer or coarser grit, a wire wheel for shaping or cleaning metal, a buffing wheel for polishing, a cutting wheel for wood or metal, specialized wheels for grinding or cutting stone, or even a specialized wheel for cutting gemstones.
While grinding, shaping, and buffing metal are the primary uses of a bench grinder, you absolutely can use these tools on wood, as well. With the right wheel, your bench grinder can sand, cut, shape, buff, smooth, or polish a wide variety of woods. Typically, however, you won’t want to use a bench grinder for very soft woods; these tools are best used on hard materials.
Yes. Most bench grinders come with multiple wheels that correspond to different tasks. Take time to consider the task at hand, and select the correct wheel for the job.

WEN 4276 6-Inch Bench Grinder
Do you have a small shop that you do occasional work in? If you do, then maybe you have decided it is time to get a bench grinder, but you find yourself asking what the best bench grinder is. Well, bench grinders can make so many task easier from making smooth edges on things to being able to repair old tools and get longer life out of them. Due to all the positive aspects of a bench grinder it is a good idea to get quality one, but if you aren’t going to use it a lot you don’t want to break the bank. That is where the WEN 4276 6 inch bench grinder really shines. It is small and affordable, but will still last a long time and has some great features which you will learn about in this bench grinder review. Check latest here
Top Features of the WEN 4276 6-Inch Bench Grinder
Staring off the WEN 4276 bench grinder is small at only 16 pounds and total dimensions of 14x10x15 inches. This means it can fit on nearly any bench without any problems. Even though it is small however it still has a solid motor in the housing. The motor in this little bench grinder is 2.1 amps which if you read more bench grinder reviews you will find is a pretty standard size for 6 inch grinders. The motor allows the wheels to spin at 3450 rpm under no load which is plenty quick enough to work on drill bits or mower blades, and even fast enough that you can remove material on wood quickly.
The WEN bench grinder comes with the standard 36 grit and 60 grit wheels and they measure six inches by three fourths inches. The arbors are a half an inch which is a good size to help keep the wheels on. The motor housing is quality metal and the cast iron base is strong to help keep the table grinder anchored solidly to your bench. Changing the wheels on this grinder isn’t a challenge either. The eye guards and housings were designed to be easily removable so you can change your wheels quickly, but they still provide maximum protection so stray material does not end up in your face.
The tool rest on the WEN 4276 Bench Grinder are adjustable which is great for making it easy to work on many different things. It helps you get the tool in the right position so you can easily grind on it without damaging it or getting tired. Another top aspect of this bench grinder is it comes with a flexible light to help make your work easier. While a light attachment isn’t an uncommon feature for bench grinders to be able to get one in this price range is a nice little bonus. While the light may not be LEDs or as nice as some others it still works well and any extra light to help you see what you are grinding on is useful light.
One question you may have though is what if I don’t have a work bench, but still want a bench grinder? Well, this particular model has a pedestal that you can buy to go with it. This is an added cost, but it can allow you to get a bench grinder without having a bench and it is also cost a lot less than a bench. Another perk of mounting the grinder to the pedestal is it makes it easy to move it around. If you work on location a lot, but still want a mobile unit, then you might want to consider going this route.
Customers Opinions on the WEN 4276 6-Inch Bench Grinder
So, reading bench grinder reviews can be helpful, especially for finding out the features of a particular bench grinder, but the most useful information is what real customers think about it.

One of the main aspects they point out about this grinder is the price. It is one of the most affordable on the market, but still packs decent grinding abilities. You can work on mower blades, and small tools without any problems. Many people comment on easy setup is, which is really good especially if this is your first bench grinder. The motor also spins up quickly to get the wheels at full speed and the motor is quite. The fact that it is quite is nice if you work in a small garage in a subdivision or along those lines.
Also, the grinder functions well and there is not a lot of vibration. For being smaller sized and weight vibration might be a concern, but when mounted properly the cast iron base does a great job of keeping it anchored to the table. The motor housing is made well also so this bench grinder is durable and will last for years.
Some complaints on this grinder though is the wheels it comes with aren’t the best. They can be out of round which causes them to wobble, and they also don’t have the best grit surface causing a lot of heat and stress on the motor. Also, this bench grinder isn’t meant for really heavy work. Some people have complained about the motor bogging down and dying, but that could be from improper use. If used properly this bench grinder is great for the price.

When it comes to bench grinders, WEN, a well-known power tool company, has worthy competitors, such as the WEN 4276 and the WEN 4280. While both of them look similar, they have distinct features, which I will review in this article.
If you are considering getting a WEN bench grinder, check out my comparison below as I point out what makes these two powerful units similar and different from each other. This will help you decide which one you should buy for your needs.
A Quick Review of the WEN Bench Grinders
These two WEN bench grinders have varying wheel sizes (6-inch and 8-inch) so they cater to different purposes. They both have work lights and other convenience features and both will be ideal for most sharpening tasks in your garage or workshop.
Before we dive into the similarities and differences between the products – and their resulting advantages and disadvantages – let’s start with a brief review of each.
WEN 4276 2.1-Amp 6-Inch Bench Grinder with Light
A small but powerful at-home bench grinder with 3,450 RPM. This lightweight model is ideal for beginners or those who are looking for a grinder simply for home repairs. It comes with a flexible work light to illuminate your work material for better accuracy, and a wheel guard removal feature to move your projects along quickly and smoothly.
This 6-inch bench grinder has a 2.1-amp motor that runs up to 3,450 RPM on its no-load speed. With its work light, you will easily see your material even in a dark garage or work area (you do need to buy a 40-watt bulb separately). Each of the 6-inch wheels has a 3/4-inch thickness and 1/2-inch arbor size.
Because of its lightweight design, at only 16 pounds, it is a decent choice for beginners or those who only want to use them for home repairs. Since the light is flexible, it is easy to position your material for accuracy.
The 36-grit and 60-grit wheels are supported by a heavy-duty base for stability while the eye guards will protect the operator during the sharpening process. If you already have a cast iron stand compatible with this bench grinder, it is easy to set up and will make your job fuss-free. I like that it has a pair of adjustable tool rests for your material.
WEN 4280 5-Amp 8-Inch Bench Grinder with Light
A heavy-duty, variable speed bench grinder. Great for working on larger materials, this unit can handle your typical home and garden tool sharpening, while it’s slower speed function and higher grit is applicable for knives, chisels and other delicate tools. It comes with a flexible work light to illuminate your work material for better accuracy, and a wheel guard removal feature to move your projects along quickly and smoothly.
As an 8-inch bench grinder, WEN 4280 is equipped with a variable-speed feature that lets it switch between 2,000 and 3,400 RPM. This makes it ideal for both slow-speed operations, such as with woodworking chisels and low-grit sharpenings, such as with lawnmower blades and metalwork. Like the 6-inch model, it also has a flexible work light that you can bend for ease of accuracy.
It has a cast iron base that makes it sturdy and less likely to tip over. What’s more, this one has an 80-grit and a 36-grit, making it ideal for removing material from sensitive tools. With its 5-amp motor and its 1-inch-thick grinding wheel, it will cater to larger objects that need to be sharpened.
over, this unit weighs 41 pounds, measures 17 x 18.1 x 13 inches, and has a 5/8-inch arbor size. I also like that it has a wheel guard removal mechanism for quick changing of discs depending on your needs.
WEN 4276 vs. WEN 4280: Similarities
As both bench grinders are from the same manufacturer, it makes sense that both of them have major similarities. Let’s have a look at some of them:
A bendable light is included with these two bench grinders – a feature that provides better accuracy for the user. It is a convenient plus point for both WEN bench grinders because you don’t need to add a work light to your desk, reducing the footprint on your table.
By having a work light in your grinding area, it will assist in avoiding accidents and also help attain the right sharpness that you want to achieve for your material of choice. Garages and workshops are often dim (and sometimes gloomy!) so having a work light to guide you will help save errors and keep you and your material safe from harm.
Wheel Guard Removal
Having a wheel guard removal feature on both bench grinders will help to speed up your task at hand. This is especially useful when you are trying to meet a deadline and you want a safe way to remove the wheels to replace with a different grit or brand.
Both of these WEN bench grinders are backed by a 2-year warranty, as long as they have not been misused or repaired by someone else. They can be taken to any WEN factory for repairs without charge to the purchaser.
WEN 4276 vs. WEN 4280: Differences
Although they are both from WEN, these two models have distinct differences, which we will discuss below:
While the WEN 2476 has a speed of 3,450 RPM which is fixed, the WEN 4280 has a variable-speed feature between 2,000 and 3,400 RPM. This makes the WEN 4280 more ideal for delicate steel such as knives and woodworking chisels.
Choosing the appropriate speed for your needs is important because it can make or break your material in question. High speeds are okay for lawn mower blades, metalwork, and the like. However, for sensitive materials such as knives, you need slower speeds to avoid burns. Consider what material or tool you want to sharpen before getting a bench grinder.
While the WEN 4276 has a 1/2-inch arbor size, the WEN 4280 has a 5/8-inch one instead. This is a likely case due to their difference in wheel size.
Although I’m sure I already gave it away in the intro, these two WEN bench grinders differ mainly in their wheel sizes. The WEN 4276 has 6-inch grinding wheels while the WEN 4280 sports 8-inch wheels.
The 6-inch and 8-inch wheels have different applications. For instance, smaller objects are okay for 6-inch wheels but they usually have a faster speed and are ideal for high-speed removal of material. For finer sharpening that will not burn the material, a slower speed is needed and it is often seen in 8-inch units. over, bench grinders with 8-inch wheels will cater to bigger objects easier.
60-grit vs. 80-grit
While the WEN 4276 has a 60-grit and a 36-grit in its set of wheels, the WEN 4280 has an 80-grit instead of a 60-grit, making it finer in terms of sharpening capability. This means it is more applicable for knives and very sharp and delicate tools.
That said, the wheels can easily be bought later on and exchanged.
Which of the WEN Bench Grinders Should You Get?
I’d also recommend the WEN 4280 if you prefer to sharpen different kinds of metals and if you also want to use them for knives and woodworking chisels, which require slower speeds and a higher grit. If you will only use a bench grinder for general sharpening of gardening tools such as lawnmower blades then the WEN 4276 is already sufficient.
In the long run, you should decide which WEN bench grinder you want to get. The most important factor to consider is that it fits your needs since not everyone works under the same conditions or works to sharpen the same sets of materials.
I hope that this guide helped you somehow in choosing which bench grinder will work for you. Both of them are worthy competitors but their features make them ideal for different situations.
