Buying guide for best bench grinders

There’s no doubt that a good bench grinder is an indispensable tool in a pro shop. You may not think of it as a priority for the home workshop, but ask the people who have one and they will probably say they wouldn’t be without it. A variety of sizes and power outputs ensure there’s something for every user, from the hobby machinist or mechanic to the full-time professional engineer.

BestReviews is here to help you decide which of those options will best fit your needs. We can provide the information you need to make the right buying decision for your workshop.

As always, we’ve selected a top five. These are the models that receive our recommendation. Each one offers class-leading standards of performance and value.We’ve also compiled the following bench grinder shopping guide if you would like more details before you buy.

You should always bolt down your grinder. If you need to move it around, consider buying a purpose-built, heavy-duty stand, giving you mobility without sacrificing stability.

Why you need a bench grinder

A bench grinder is a surprisingly versatile tool. Grinding to shape pieces of metal is an obvious task. A grinder is often used for sharpening, too – everything from kitchen knives to lawn-mower blades. Change one of the grinding wheels for a wire wheel and it can remove rust or paint. There are also flap wheels for polishing and leather wheels for honing.

Visit your local engineer, auto shop, or hardware store and see how much they charge for relatively simple jobs – jobs you could do yourself if your workshop had a bench grinder.

Do the math and you’ll see how quickly it will pay for itself!

Bench grinder features to consider

A bench grinder is a fairly basic tool. It contains an electric motor that drives a pair of shafts. Each shaft is attached to a grinding wheel, with guards for safety and tool rests for easier control of the workpiece.

While all bench grinders have a similar design, there are variations in size, power, construction, and other features.

Size and power

The diameter of the grinding wheel determines the size of the bench grinder. In general, a bigger wheel has more mass, requiring more power to turn and maintain speed under load (most bench grinder wheels rotate between 3,400 and 3,600 rpm).

Budget bench grinders are often rated in amps, while more powerful models are rated in horsepower (ranging from about one-quarter to one horsepower). It’s important to note that all of these ratings are under “no load” conditions – the motor is running but not grinding anything. Grinding or sharpening slows the wheel a fraction. If the motor is strong enough, the drop in speed is barely noticeable. However, if there’s too little power, the wheel won’t cut efficiently. In rare cases, it could even stall. Therefore, more power is better.

• Six-inch bench grinder: Many people find that for general-purpose use, a six-inch grinder with a wheel width of either one-half inch or three-quarter inch is perfectly adequate for most jobs, such as sharpening tools and removing rust. We’d favor a one-half horsepower motor for a six-inch grinder, but we’d consider one-third horsepower a basic minimum for light-duty home workshop use.
• Eight-inch bench grinder: There are benefits to having the larger eight-inch wheel, which is usually one inch wide. It provides more cutting area, so the material you’re grinding is removed more quickly. If you’re sharpening tools, you can work on more of the blade at once, so it’s easier to get an even edge. Eight-inch grinders need more power to rotate at the same speed (there’s increased mass to move), so here we prefer to see a three-quarter horsepower or greater motor. The best professional-grade bench grinders deliver one horsepower.
• Slow-speed bench grinder : This is the exception to the general 3,400 to 3,600 rpm rule. These machines are mostly marketed to woodworkers. Woodturning and carving chisels can be damaged by the high temperatures created by ordinary grinders, so they have lower speeds of 1,725 rpm. Most of these are eight-inch models, but because they run more slowly, a one-half horsepower motor is fine.
• Variable-speed bench grinder: There are a few bench grinders on the market that offer variable speed. Not surprisingly, these are a little more expensive than their single-speed counterparts. If you spend equal amounts of time working with wood and metal, one of these could be a good investment. Most people are focused on one or the other, so one speed is usually all you need.

Construction

Substantial construction gives a bench grinder the rigidity you need to do accurate work. Grinding is usually quite a loud task, but a heavy-duty build helps to dampen the vibration and so reduce noise levels.

• Steel is solid and durable.
• Cast iron is even better, and it’s what you’ll find on high-quality machines, though it does cost more.

Additional features

• Guards: It goes without saying that guards are vital. On some bench grinders, a spark guard and eye shield are separate; on others, they’re combined. As long as they’re easy to adjust, the type you choose isn’t important.
• Tool rests: These should always be fitted. These can be set for particular grind angles and make it easier to control the workpiece.
• Lights: It’s important to see what you’re doing. Some bench grinders have small LED lights directly above the grinding wheels, others have a lamp on a flexible stalk.
• Feet: Rubber feet help dampen vibration and reduce noise.

Bench grinders produce lots of small particles and dust. Sealed bearings prevent these from getting inside the machine where they could seriously damage rotating components.

Bench grinder prices

Bench grinders vary in price from 40 to 300 and more. There’s so much choice, it’s really a question of deciding on the specifications you need and shopping around for the right price.

At the budget end of the market, you’ll find perfectly good six-inch bench grinders for as little as 40 or 50. and up to about 100. These are ideal for occasional light-duty work, and you’ll recover your costs in no time.

If you grind or sharpen on a regular basis, you’ll want to invest in higher performance – either a more powerful six-inch grinder or an eight-inch machine. A professional-quality bench grinder from a respected brand will cost anywhere from 100 to 300.

The very best tools can cost 300 and more. For that kind of money, you’ll get a powerful, robust, and dependable bench grinder that will last a lifetime.

Tips

Leave plenty of space around your bench grinder so you can manipulate workpieces without bumping into things.

FAQ

Q. What do grit numbers mean on grinding wheels?

A. The grit number tells you how coarse the wheel is. Most bench grinders come with two wheels.

• A 36-grit wheel is designed for Rapid material removal.
• A 60-grit wheel is for general-purpose shaping and sharpening.
• A 100-grit wheel is for fine sharpening.
• A 150-grit and higher wheel is for polishing.

Grinding wheels come in different materials, too. Standard wheels are often aluminium oxide or silicon carbide. White wheels, a type of aluminium oxide, are usually used on slow-speed bench grinders. Diamond wheels are used for sharpening very hard materials, such as cutting tools with carbide tips.

Q. Why are the guards and tool rests adjustable?

A: As you use your bench grinder, the grinding wheel wears away. If you don’t adjust the spark guards and eye shields, you could find yourself showered in tiny red-hot particles! Adjusting the tool rests helps maintain optimum performance. If the gap between the wheel and tool rest gets to big, you get excess vibration, and the wheel won’t cut as well as it should. There’s also the chance of the workpiece snagging on the wheel and getting pulled downward, which is very dangerous. The manufacturer’s instructions will tell you what the gap ought to be. Adjustments should be made regularly.

Q. I notice some people keep a jar of water by the grinder. Why?

A. Heat builds up rapidly in the metal you’re grinding, so cooling it occasionally lets you work longer. It’s also useful when sharpening cutting tools like chisels, which are heat-treated (tempered) when they’re made. If they get too hot, you could remove the temper, and they could go blunt very quickly. Dipping the tools in water reduces the chances of this happening.

The 10 Best Metal Bench Grinders to Smooth Out Your Welding Jobs in 2023

Look in any common everyday workshop, and you’ll notice that around 75% of all tools e particular trait, namely that they are either sharp or pointy, and their efficiency is usually based solely on this particular trait.

Since all tools tend to dull over time, it goes without saying that you will need some method of keeping them sharp and pointy as much as possible, and that’s where a good table grinder can come in handy.

What Is a Metal Bench Grinder?

For those of you that don’t know, a bench grinder (also known as a table grinder) is a type of grinding machine that uses an abrasive wheel made out of a wide variety of materials, and this grinding machine is designed to be a benchtop-type tool.

While most commonly used to sharpen metallic objects, these bench grinders can also be used as a means to smooth out any excess materials that appear when you cut metal, as well as the excess material that is most commonly associated with welding jobs, although the latter is best performed with handheld angle grinders.

The exact purpose of this machine changes based on the bond and the grade of the grinding wheel, and you can even change the grinding wheel entirely for a wire brush or a buffing wheelto turn the entire machine into a polishing device.

Whichever the purpose, bench grinders are a staple in any workshop, especially those that have to do with metalworking or machinery.

Where Can I Buy a Metal Bench Grinder?

When browsing for tools, we recommend that you always go to a real-life hardware store where you can see the product for yourself, since bench grinders are not exactly easy to judge based on pictures, videos, and reviews alone.

However, if you have no way of visiting an actual hardware store that sells bench grinders, then you’ll probably end up shopping for them online, and there’s no better place to start looking for a brand-new bench grinder than Amazon.

You see, if you do happen to be unpleased with the product, you always have the option of returning it, and Amazon has a very flexible return policy where you will get your money back in no time.

However, that’s very unlikely to happen thanks to Amazon’s user reviews system, where any potential customer can read what all other users think about the products. Not only that, but a lot of users even go an extra step and include pictures in their reviews and even short videos showcasing the product.

JET JBG-8B 8-Inch Bench Grinder

JET is a big name in the tool manufacturing industry, and one of their products, the JET JBG-8B 8-Inch Bench Grinder, made it on our list because of how good and feature-packed it is.

It too can hold 2 grinding wheels simultaneously, and the default package will provide you with a fine 60-grit grinding wheel, as well as a much coarser 36-grit wheel, both of which are 8-inches in size, making it yet another machine that is great for both fast material removal and finer grinding jobs as well.

Speaking of finer precision jobs, this grinder provides you with adjustable tool rests, so you don’t have to worry about making any mistakes or eating up too much of your workpiece because you weren’t holding it steady enough.

The wheels are powered by a 1 HP 115V motor that can spin them at up to 3450 RPM, and you don’t have to worry about the machine moving around because of the vibrations since it has a rubber foot that ensures proper grip to the surface you placed it on. Not only that, but you can even bolt it down if you’re concerned about the machine’s stability.

The overall build of the machine showcases that it’s made to last. For starters, it has totally enclosed pre-lubricated ball bearings, so the grinder won’t end up grinding itself. Secondly, it has cast iron wheel guards for added ruggedness, and the dust vents make it so that all debris is efficiently removed from the grinder, thus preventing any type of clogging.

so, the grinder has all the typical user-protection features you’d expect from a typical bench grinder, including one-piece spark guards and large eyes shields that are all easily adjustable.

Thanks to this durable build and the fact that it was constructed following strict production guidelines, this JET bench grinder meets all CSA safety standards, making them ideal for industrial workspaces.

If JET impressed you with their product, you should take a look at the product’s Комментарии и мнения владельцев section and see just how satisfied customers are with the product. Simply visit the JET JBG-8B 8-Inch Bench Grinder’s Amazon page and check out the Review section.

• Holds two grinding wheels at once

• Adjustable tool rests
• Can be bolted down
• 1 HP engine

JET JBG-6B 6-Inch Bench Grinder

The next bench grinder on our list is yet another JET grinder, and it’s similar to the previous model, only that the most notable difference is that this particular model holds 6-inch wheels instead of 8-inch wheels.

Other than that, the product is pretty much identical, since it too has a cast iron body, completely enclosed pre-lubricated ball bearings, dust vents, rubber mounts, etc.

It too is powered by the same 1 HP motor and can reach speeds of 3450 RPM, so the only real difference in the workflow is that you’ll finish the grinding job a bit slower with this model because of the smaller grinding wheel.

However, since this bench grinder only holds grinding wheels that are only 6 inches in diameter, it is also much more compact, and a lot lighter than the 8-inch model, standing it at just ‎18 x 10.5 x 8.5 inches, and weighing in half as much as the 8-inch model (just 32 pounds).

Because this product is built just like the previous one and is manufactured while following the same strict guidelines and electrical requirements, it too meets all CSA standards.

All in all, if JET bench grinders seem like your thing, but don’t have the space to hold the bulky 8-inch version, you can go ahead and get the JET JBG-6B 6-Inch Bench Grinder instead.

• Much smaller than the 8-inch model
• Much lighter than the 8-inch model
• Holds two grinding wheels at once
• Meets all CSA standards
• Adjustable tool rests

Table Grinder’s Buying Guide

After reading up on our 10 entries, you’ve probably noticed that we kept focusing on certain criteria over and over, and that is merely because bench grinders as a whole are very simple devices, and there are very few things that you need to look for to get something that suits your needs.

That being said, we went ahead and wrote down a small guide that will showcase what exactly you should be looking for when buying a new metal bench grinder, all so that you can make a better and more informed decision about your next big purchase.

Build

It goes without saying that quality should be your main concern when buying just about anything, especially a tool like a bench grinder. That being said, check out the materials that make up the bench grinder and make sure that they are as durable as possible.

Most bench grinders nowadays use cast iron to make up the bulk of the body, so naturally, these tools will be very durable. However, another neat way to figure out just how durable a bench grinder is would be to check out just how long the warranty is since that can be a tell-tell sign of good or bad craftsmanship.

For example, most generic bench grinders will have the standard 2-year warranty, but the top-quality ones can even come with a 5-year warranty.

Size of the Metal Bench Grinder

Not everyone has the same storage space at their disposal, and some of you may even have their workshop filled with all kinds of other tools, leaving very little bench space for a grinder.

Because of that, try to look for bench grinders that are as compact as possible. If you’re interested in a particular bench grinder, but the official description has no mentioning of the device’s actual size, one way to tell how big it is is to look at the grinding wheel.

This will not only be a clear indicator of the bench grinders’ width and length, but since most bench grinders share a standard design, it can also let you know just how tall the grinder is as well.

The Size of the Grinding Wheel

We talked about how the size of the grinding wheel is important in assessing the size of the bench grinder, but this particular feature is important for other reasons as well.

You see, depending on the side of the wheel, the bench grinder can be used for different jobs. For example, while very small wheels can be used to simply sharpen the typical kitchen knife, the larger wheels from bigger bench grinders can be used to smooth out excess steel for welding jobs.

Besides, a larger wheel means a larger grinding surface area, which means that you can sharpen or smoothen more in less time.

The Grinder’s Motor Power

Grinders are mechanical devices, and like all mechanical devices, it is driven by a motor.

Sure enough, old-fashion bench grinders can be powered manually using either handles or pedals, but since we’re living in the 21st century, we’ll consider that you are mostly interested in the ones powered by electric motors, since they don’t get tired, and they maintain the same work efficiency throughout their entire run.

Just like any other electrical tool, the power of the motor is a core aspect of its functionality, and more powerful motors are better since they allow you to grind through harder materials for longer periods, thus providing you with the most flexibility

The Grinder’s Motor Speed

The grinder’s motor speed goes hand in hand with the motor’s power, and it indicates just how many rotations-per-minute (RPM) the grinding wheel will perform once the bench grinder is turned on.

As such, some of the more powerful bench grinders can reach up to 3000 RPM, while the more budget-friendly grinders spin at around 2000 RPM.

Having more RPM means you will be able to grind harder materials much faster, therefore allowing you to get the job done more quickly.

Besides, most modern-day grinders have a way of adjusting the speed of the grinding wheel anyway, so a bench grinder with a maximum motor speed of 3000 RPM can spin at 2000 RPM, but the same thing cannot be said the other way around.

Besides, if you purposely slow down the grinder, you can go ahead and grind, smoothen or sharpen much softer materials with much greater precision.

Best Metal Bench Grinders: Closing Thoughts

As a metal worker, you may have realized by now the importance of a bench grinder, and how useful it can be to have one around the workshop. It doesn’t matter if you are planning to sharpen a knife or sand down a weld, a grinder is a must-have, and an electric-powered bench grinder is the best that you can possibly get.

As such, take your time reading the description of each of our suggested products, and then use what you learned in the second part of the article to determine which is the right bench grinder for you.

A bench grinder is probably not a tool you’ll use every day. However, if it’s available and set up correctly, you’ll be surprised how often it comes in handy for everything from sharpening tools to rounding over thread ends on a cutoff bolt. We’ve assembled these tips to help you get the most out of your grinder.

Keep a Container of Water Handy

Most chisels and other cutting tools are made of tempered steel. If the steel gets too hot and turns bluish black, it’s overheated and won’t hold an edge very long. To avoid ruining the edge of a tool by overheating, keep water nearby to cool the tool. A good technique is to move the tool once across the bench grinder for no more than a few seconds. Then dip it in the water. If the steel edge does overheat and turns color, grind the edge back to good steel and start over.

Grind Small Objects Safely

Hold small objects with locking pliers. This keeps your fingers a safe distance from the grinding wheel and protects them against burns from the hot metal. It also gives you better control over the grinding process.

Make Tool Sharpening Guides

Here’s a better way to hold tools securely while you’re grinding them—and take the guesswork out of creating the right bevel angle. It’s a short piece of 2×4 with an angled end and a 1-1/4-in. hole for a clamp. I made one for sharpening chisels and plane blades, and a few more with different angles for wood-turning tools. Large labels with the tool’s name tell you which blocks are for which tools. For a Delta grinder with a 6-in.-diameter wheel, a 5-1/2-in.-long piece of 2×4 aligns the tool to the wheel just right. For other bench grinders, you may need to adjust this length. Note: The angle you cut on the block is not the same as the tool’s bevel angle. But let’s skip the math. To determine the block angle, turn off the grinder and hold the tool’s bevel flush against the wheel. The angle of the tool shaft to the workbench is the angle to cut on the 2×4.

Consider a Low-Speed Grinder for Sharpening

Unless they’re variable speed, most bench grinders run at about 3,450 rpm. If you’re careful and keep the wheel dressed (more on that in another tip), these high-speed grinders work fine. But for sharpening garden and other tools, a low-speed grinder running at 1,750 rpm is a better choice. The lower speed reduces the chance you’ll overheat the edge of your tool. Another advantage of a low-speed grinder (100 to 150) is that this type typically includes friable white grinder wheels, which do a better job of sharpening than the gray grinder wheels usually included with high-speed grinders. See how to use an angle grinder.

Dress Wheels Frequently

Wheel dressing squares the face of the wheel, but more important, it exposes new grit for more efficient cutting. As a wheel is used, the spaces between the cutting grit can become clogged, and the grit itself dulled. A wheel in this condition can cause overheating and slows material removal. A wheel dresser like the one shown here (15 to 30) has a bar with diamond grit impregnated in it. Holding the bar against the spinning wheel cuts away the surface to expose new grit, squares the face of the wheel and rounds the wheel. To use a dressing tool like this, start the bench grinder and wait for it to reach full speed. Then press the diamond wheel dresser against the spinning wheel, holding it perpendicular to the face of the wheel. Be sure to wear a good-quality dust mask. The fine aluminum oxide dust is very bad for your lungs. Draw a pencil line on the wheel before you start to help you gauge when you’ve removed enough material from the wheel. Dress the wheel just until the pencil line disappears.

Watch for the Sparks to Come Over the Top

When you’re sharpening a chisel or other tool, you can tell when the edge is getting sharp by watching the sparks. When the edge is blunt, the sparks are deflected downward. But as the edge gets sharper, the sparks roll over the tool and cascade down the surface facing you. When you see this start to happen, be careful about grinding much more because a thin edge is very vulnerable to overheating.

Make an Angle Gauge

Chisels and other cutting tools work best if their edges are ground at the correct angle. You can search online to find the optimal angle for whatever tool you’re sharpening. Most wood chisels should be ground to about a 25-degree angle with a secondary micro-bevel angle of 30 degrees on the tip of the blade. An angle gauge allows you to set the tool rest at the desired angle. You can make an angle gauge from a thin piece of cardboard using an inexpensive protractor. 1. MARK THE ANGLE ON CARDBOARD Align the center mark on the protractor with the top edge of the cardboard. Then turn the protractor until the desired angle is also aligned with the top edge. Draw a line along the protractor to mark the angle. Don’t forget to label the angle. Cut along the line to create the gauge. 2. ADJUST THE TOOL REST Set the cardboard on the tool rest and adjust the angle of the tool rest until the wheel contacts the center of the angled portion of the cardboard gauge.

Upgrade the Tool Rest

Inexpensive bench grinders have tool rests that are finicky and difficult to adjust. If you do a lot of tool sharpening or simply want a bench grinder tool rest that’s easier to adjust, consider adding a stand-alone tool rest. There are several variations, some made for specific tasks like sharpening lathe turning tools. This Veritas model has two adjustments for positioning and aligning the tool rest, and levers for easy tightening. You can also buy an attachment that holds chisels or plane irons.

Make Your Grinder Portable

Even the most nicely organized home workshops don’t have enough bench space to devote a section to a bench grinder. A good solution is to mount your grinder to a board or small stand so you can clamp it to the bench when you need it, and store on the shelf when you don’t. The compartment on this grinder stand is a good spot to keep your dressing tool and safety glasses so they’re handy when you need them. For a fancier version, build a little drawer to fit the space under the grinder. The stand is built from two 12 x 16-in. pieces of 3/4-in. plywood separated by two 4 x 12-in. uprights. We used two 5/16-in. bolts with washers and nuts to attach the grinder, leaving enough space in front of the grinder to mount a stand-alone tool rest.

Easy-to-Clamp Mobile Base

Shazam! Fasten your bench-top tools to your workbench in seconds. Bolt 3/4-in. plywood bases on the tools and then glue and screw a wood strip along the front edge to fit into a woodworking vise. Crank this strip into a vise to lock the tool into place. If you don’t have a vise, drill a couple of clearance holes along the face of the wood strip on the base and drive screws through the strip into the edge of your workbench. Then just unscrew to remove the tool.

Set Up a Polishing Station

A bench grinder fitted with a wire wheel on one side and a cotton buffing wheel on the other side, or buffing wheels on both sides, makes a great cleaning and polishing tool. You’ll also need a set of polishing compound sticks (14). Polishing compound sticks are color coded to indicate the grit, from coarse to very fine. To use the polishing wheel, hold the stick against the buffing wheel as it spins to transfer some polishing compound to the wheel. Then hold the object lightly against the wheel and let the compound polish the surface.

Sharpen Your Lawn Mower Blade

Sharpening your lawn mower blade is easy with a bench grinder. Grind the tapered cutting edges with a grinder only if you see nicks in the blade. Follow the factory angle of the cutting edge. The grinder will remove nicks in the blade much faster than you can file them.

Not All Grinding Wheels are the Same

You can use two kinds of aluminum-oxide wheels to sharpen your chisels; one is blue-gray and the other white. We used the darker-color wheel, which is harder and will keep its shape longer. The drawback, however, is that it grinds hotter than the softer, white wheel. Too much heat will weaken the steel. The soft wheel will need more frequent shaping with a dressing tool, but you’ll be less likely to burn the edge of your chisel while grinding. For best results, use a 100-grit wheel to shape your chisel blades.

Know When to Replace a Wheel

Slide the wheel over your finger and tap the wheel in four places with a screwdriver handle. All taps should sound the same. If they don’t, scrap the wheel. It’s cracked.
