The Best Die Grinder, According to 9,000 Customer Reviews

Welcome to the Thomas guide to the best die grinders 2023. Thomas has been connecting North American industrial buyers and suppliers for more than 120 years. When you purchase products through our independent recommendations, we may earn an affiliate commission.

Grinders are multifunctional electric or battery-powered items of equipment used on a wide range of building materials. General grinders are used for sawing, cutting, sanding, and brushing, due to the sheer force they exert on the material. Die grinders, on the other hand, obtain their cutting strength through high speed, rather than physical force.

Despite their horsepower rating of ⅓ or less, these tools can work at such fast speeds that they can accomplish detailed work, for which they are famous. Whereas most grinders are traditionally used for metalworking, die grinders have a variety of other DIY applications, including jewelry making, crafts, and any other hobby where a small-scale cutting or grinding tool is necessary.

On a professional level, if you are a car mechanic, welder, or body shop technician, you will also benefit from having a die grinder in your arsenal for detailing work. The buyer’s guide provided below aims to aid you in selecting the finest die grinder for your specific needs.

Here is a list of the best die grinders, followed by a buying guide to help you select the best die grinders.

Best Overall Die Grinder—DeWALT DCG426B

The DeWALT DCG426B is a 20-volt electric die grinder that produces 500 MWO and can handle grinding discs up to 33 mm in diameter. The brushless motor is powered by the same batteries and charger as any other 20V MAX tool from the brand. The lack of a power cord and its lightweight design make it convenient to carry and use for extended periods of time.

A powerful led light is positioned on the nose of the tool to improve visibility, the motor is shielded from debris by a mesh cover and, because of the dual-position convenient paddle switch, the handle may be gripped in a number of ways.

One satisfied customer wrote, “Ditching a cord, having an LED light, and adjustable speed? Holy smokes. Genius. The variable speed is extremely nice when you just have some light touch-ups in a tight spot. You don’t have to worry about grabbing and bouncing around all over the place.” They also commented that the battery life lasts all day on a 5AH for regular use.

Dimensions: 17 x 10 x 5 inches

Weight: 3.36 lbs

Best Cordless Die Grinder—Dremel 8220-2/28

The Dremel 8220-2/28 set is a 30-piece kit, which includes the cordless die rotary tool, a 565 multi-purpose cutting kit attachment, an A550 shield attachment, 28 Dremel accessories, two 2.0 Ah, 12-volt lithium-ion batteries, a charger, a plastic storage case, and an accessory case. The patented EZ Twist Nose Cap makes accessory changes fast and easy without the need for a wrench, and this unit is compatible with the whole range of accessories from Dremel.

You won’t have to worry about it running out of power as you would with some other cordless die grinders because the battery reaches a full charge in just 60 minutes, and a second battery comes included in the set. Variable speed control (5,000-35,000 RPM) is operated from the easy-to-use ergonomic switch located on the side of the product.

Even professionals were impressed by this cordless die grinder, and one wrote, “This thing is powerful. Runs for a long time on battery charge.” Another happy customer added, “It seems to be quite sturdy with a strong, reliable motor.”

Dimensions: 4 x 13.75 x 9.28 inches

Weight: 2.1 lbs

Best Pneumatic Die Grinder—Chicago Pneumatic CP875 Angle Die Grinder

Although the attached air hose may not allow for portability, the Chicago Pneumatic CP875 sports a compact, solid aluminum housing and a built-in air regulator, which, along with its compact size, can handle most tough jobs in limited spaces. These pneumatic power tools are considered heavy-duty die grinders and are mainly used for rough cutting (not to be confused with cutoff tools).

Mirroring our sentiments exactly, one happy customer wrote of this tool, “This little die grinder has some serious cajones; far more than you would expect for the size.” Unlike other models, i.e., corded electric die grinders or battery-powered cordless die grinders, pneumatic tools achieve speed control with a twist throttle for precise cutting. The series also has a kit that comes with 13 grinding wheels’ accessories and a carrying case.

As one of the many happy customers summed up, “This particular Chicago Pneumatic grinder has been my go-to for years. My last one lasted me five years before it finally gave out, and that was with HEAVY usage, oiled daily, and greased at least once a month.” They also commended it for being lightweight (“compared to the ones my coworkers use”), compact (“small enough to where it fits comfortably in my small hands”) and quiet.

Dimensions: ‎4.2 x 7.5 x 2.6 inches

Weight: 1.1 lbs

Best Compact Die Grinder with Compressed Air—Ingersoll Rand 3107G

The Ingersoll Rand 3107G Edge Series is small and lightweight, weighing in at only one pound. It features a ball-bearing construction and is pretty sturdy, compact, and lightweight, allowing you to operate it anywhere with ease. It comes in straight and right-angle options, as well.

It runs on compressed air and has a ⅓ horsepower engine, a ¼.inch collet, a rear exhaust, and a self-locking throttle. Despite its small size, it has a high RPM of 27,000 that will blast through even the toughest jobs.

The curved grip provides better comfort and control, and the ergonomic design allows for superior torque precision, as well as increased productivity and safety, allowing you to use it all day without concern. Many customers commented on this tool’s high power, and compact design, and one wrote that it’s also “very convenient and perfect for sharpening a lawn mower blade.”

Dimensions: 9.5 x 6.25 x 1.75 inches

Weight: 1 lb

Best Right Angle Die Grinder—AIRCAT 6255

If you’re searching for a comfortable angle die grinder for those hard-to-reach spots, the Aircat 6255 has an angled head and ergonomic design that is made for working in difficult-to-reach areas. This tool is described as having good internal mechanics and has a 0.5 horsepower motor, and a free speed of 20,000 RPM.

This angle grinder features a unique silent technology that reduces vibration and noise levels (below 82dB) without lowering the working torque, making it ideal for working in a home environment. The AirCAT angle die grinder also has a feather trigger and a rear exhaust port design that safely directs air away from the user.

One customer, a novice, wrote that this angle grinder “is easy to handle. The trigger is the best of these types I’ve used with no false activations.” Another buyer, a professional mechanic with over 10 years of experience, agreed and wrote, “I love this Aircat angle die grinder… It is actually very easy to control your speed variety… The tool quality is built perfect; when you look at it, you know it’s not cheaply made.”

Dimensions: 7.1 x 3.1 x 1.5 inches

Weight: 1.19 lbs

Best Extended Die Grinder—Berkling Tools BT 6321-7

Anyone looking for a professional tool for tight spaces and difficult-to-reach areas will appreciate the size and convenience of the Berkling BT 6321-7. This product line also offers 7- or 12-inch extensions, as well as a straight and right-angle grinder, so you can choose the one that best suits your needs. Its pneumatic 0.5 horsepower motor makes it perfect for difficult applications like porting, weld grinding, and edge smoothing.

For grip comfort and cool air insulation, this power tool incorporates a strong composite rubber over-molded lightweight aluminum casing. The Berkling die grinder is designed for high-speed grinding and also has an air regulator on the handle for convenient access and adjustment of the motor speed.

Customers agree that this is a powerful die grinder, good for detailing and heavy-duty work. “l successfully ground a rounded nut on a catalytic converter and the tool served the purpose,” wrote one auto mechanic. “I like the weight of it. It’s not too heavy for extended use, and it’s good at getting into places a normal length die grinder won’t reach.”

Dimensions: 13.4 inches (L)

Weight: 2.87 lbs

Best Die Grinder for Tight Spaces—Astro ‎APT-218

The Astro APT-218 is an ⅛-inch pencil die grinder designed for heavy-duty work in confined spaces. Unlike most die grinders, its size (5.2 x 14.5 x 19.7 inches) allows it to fit into practically any space, without sacrificing its power, as it revolves at 56,000RPM.

Its powerful motor can handle cleaning dies, rotors, and brake pads, so you can use it both for heavy-duty work and finishing touches, thanks to its precision bearings. As with most pneumatic die grinders, simply twist the throttle mechanism for speed variety and smooth operation.

One customer who works in aviation praised these “professional” and “spectacular” grinders, and described, “They spool up, have torque, and will shear ⅛ cutters if you let them get away from you.” Another professional wrote that “it is much, much thinner than a Dremel… You hold it like a pencil, rather than a Maglite, which makes it a great tool… Also, it’s air-powered so you can slow your roll by adding a little pressure and let up when you’re ready to get on with it.”

Dimensions: 5.2 x 14.5 x 19.7 inches

Weight: 0.8 lbs

Best Heavy Duty Die Grinder—Makita GD0800C

The corded electric Makita GD0800C boasts a 6.6 AMP motor that can easily provide up to 28,000 RPM. The SJS technology in this straight die grinder is a mechanical brake that avoids harm to both the tool and the user by allowing the drive shaft to slide if the front grinding wheel is stopped by force.

This high-speed tool has a variable speed control dial that allows you to tailor the pace to the work at hand, ranging from 7,000 RPM to full speed. Soft start also reduces start-up reaction time, resulting in smoother starts and longer gear life. It also includes directional air-flow vents that divert the tool’s air output away from your face.

“In addition to its raw power, I also find the rigidity of the tool helps make even fine cuts more controllable,” wrote one happy customer, who also pointed out that it has a “multi-position removable side handle which adds greatly to the ease of controlling this workhorse.”

Dimensions: 5.43 x 17.91 x 3.66 inches

Weight: 3.5 lbs

Best Die Grinder Kit—Ingersoll Rand 307BK

The Ingersoll Rand 307BK die grinding set includes the 307B straight air die grinder, two wrenches, a 6mm collet, 10 abrasive stones in various shapes and sizes, and a plastic case to keep it all in. The die grinder has a maximum speed of 28,000 RPM and 0.3 horsepower, which, despite its small size, allows it to be used for deburring, polishing, porting, smoothing edges, and weld grinding.

makita, gd0600, corded, grinder

This straight die grinder also has a narrow profile and, as the grinding head is in line with the tool body, it allows for reach through spaces where angle die grinders may not fit. You can also apply greater pressure on these tools and have more control over detailed work as it can exert up to 90 PSI.

It weighs a little more than the other die grinder from the same brand on this list, however, it’s still a lightweight tool. Many customers left rave reviews stating that they have been left satisfied with their purchase—especially considering the low price—as everything they needed could be found in this compact package.

Dimensions: 5 x 2 x 2 inches

Weight: 2.1 lbs

Best Budget Die Grinder—WORKPRO Air Die Grinder

For the budget-savvy novice or professional, WorkPro Air die grinder offers great value for money. This unit comes in both straight and right-angle die grinder options. These pneumatic models also feature two collets (¼ and ⅛ inches) and it also has a latch connected to the trigger mechanism that acts as a safety lock.

This budget option rotates at a maximum speed of 25,000 RPM, allowing for precise cutting, grinding, shaping, as well as sanding, and can withstand a maximum operating pressure of 90 PSI. It is lightweight yet sturdy and its ergonomic shape makes it perfect for extended one-handed use. The rear exhaust design produces less noise and keeps the exhaust out of your face.

Many pros using the tool left five-star reviews, and one customer, a professional who uses it daily, explained that even though “it is not as refined as some higher-priced brands, it is likely one of the best you can find in this price range.”

Dimensions: 17 x 10 x 5 inches

Weight: 0.73 lbs

The Best Die Grinders—Summary

To sum things up, if you are looking for an overall powerful die grinder that is portable and has many unique features, try the DeWALT DCG426B (US149.99, Amazon). On the other hand, if you prefer using tools with an air compressor, the Ingersoll Rand 307BK (US69, Amazon) 16-item kit is a stellar option.

For a more heavy-duty die grinder, the Makita GD0800C (US246.47, Amazon) boasts a powerful 6.6 AMP motor and can deliver up to 28,000 RPM (though it’s not intended for use with a cut-off wheel or as a cutoff tool).

Choosing the Best Die Grinder—Buying Guide

There are a few essential factors to consider before purchasing a die grinder that can meet your demands. It’s also worth noting that no matter how powerful a die grinder is, it is not advisable to use it with accessories for cut-off wheels or as a cutoff tool.

Die Grinder Considerations

These power tools are pretty straightforward, with a few options to pick from, and the end result is mostly determined by the type of tip used on the die grinder. Important factors to consider are the size, motor power, power source, and whether a straight or right-angle die grinder is more suitable for your needs.


The appropriate size to purchase depends on the type of job at hand. Smaller ones are best for auto technicians since larger versions will likely not fit between the exhaust pipe and the car’s floor. The size of the tool may not be as important for welders, and generally grind components that are put flat on a workstation.

Motor Power

The power you require, like the size, is determined by the project. The motor power directly regulates the speed of the grinding wheels. Generally, the more powerful the tool, the harder it is to slow down while applying pressure. Auto mechanics who use a die grinder with accessories, such as a fibrous cutoff wheel, to cut bolts and grind off gaskets may get by with a less powerful model, but professional welders should opt for high-speed and more powerful models.

Straight vs. Right Angle Die Grinders

Angle grinders should not be confused with angled die grinders. Die grinders, whether right-angle or straight, are smaller and lighter than angle larger grinders, making them ideal for on-the-go use. But both kinds are essentially useful for the same purpose. Straight grinders might be more comfortable to work with on components that are above head, such as grinding an exhaust; while angled die grinders can fit easily into tighter spaces.

Power Source

Battery-powered cordless models are becoming popular, particularly among contractors working on remote job sites. The batteries on these units will need to be replaced often if you use the power tool for long periods. The battery pack also makes these cordless tools slightly bulkier and heavier than air-powered models.

If you own a high-quality air compressor, however, a pneumatic grinder may be the ideal option for you as you won’t have to worry about pneumatic ones running out of power. Corded electric models are also available and could be handy in a workshop, but they do have the limitation of a cord which could be an issue if working remotely.

The Best Electric Die Grinders for Heavy Duty Use 2021

Disclaimer: None of our reviews are sponsored. We earn a commission when you purchase items through our links.

Not everyone wants to carry an air compressor for their die grinder. Electric die grinders resolve that headache by making them more portable. Don’t be fooled though, just because they’re electric doesn’t mean they can’t be heavy duty.

We’ve put together this list of some of the top models around – designed specifically for heavy duty work.

Quick Picks

Here’s 3 products we picked out that thought you would be interested in depending on your budget.

The GE710 Plus from Metabo is our high end pick because it’s high quality functional build from the German manufacturer. Designed for those who need a serious heavy duty tool.

The DCG426B Cordless from DeWALT is a top seller in it’s class. Part of the 20V Max range with variable speed makes it a favourite amongst users. Backed by strong reviews by happy users.

The GD0601 from Makita might be our budget pick, however, it’s certainly not a budget product. There are cheaper models around but we think it’s worth spending the little extra to get something proven.

The Best Electric Grinder with Reviews 2021

Here’s a list of the best die grinders we found:

Metabo GE710 Heavy Duty Electric Die Grinder

  • Electronic safety shutdown of the motor if the tool jams
  • Thermal overload protection
  • Auto-stop carbon brushes
  • Hardened and ground collet chuck for precise concentricity of tools in use
  • Collet bore of the collet chuck 1/4 “
  • Variable speed: 10000 to 30500 RPM


  • Solid German construction
  • Advance safety elements built-in to prevent accidents
  • Flexibility in the types of projects and materials you can use it for
  • Easy to use in hard-to-reach areas
  • Ideal for industrial use


The Metabo GE710 Plus is our choice as the best pick for many reasons, and not the least of those reasons is the versatility solid construction of this tool.

With a variable speed motor and a selector that allows you to easily adjust the speed to fit the task at hand, this grinder will perform well on most jobs and materials.

Featuring a long spindle, the GE710 plus prevents you from bending and twisting to work at an awkward angle. The built-in safety features give you very good protection against accidents, including automatic protection against burning out the motor with extended use.

The low weight of this model makes handling a breeze during a job, and when combined with the wide range of power choices and excellent control, the Metabo GE710 was an easy choice as our Best Pick.

It doesn’t matter if you are experienced or wet around the ears, this electric die grinder will exceed your expectations.

DeWALT DCG426B Cordless Die Grinder

  • Uses battery
  • Maximum speed of 25,000 RPM
  • 20-volt motor
  • Collet uses 1/4-inch bits
  • Weighs 3.95 pounds


  • LED lights to illuminate work area
  • Variable speed
  • Brushless motor
  • Part of the 20V Max range


  • Battery power comes with the need to recharge
  • A larger grinder than some other options
  • Not the best for longer jobs


Another entry on our list from venerable toolmaker DeWALT, this grinder offers several advantages over other choices.

The most noticeable is, of course, the fact that it’s cordless. This eliminates the question of power, allowing this grinder to do its job from anywhere.

While this is an advantage, it can also be a disadvantage if the battery isn’t charged. However, DeWALT kept this in mind and designed a tool that has a very long battery life on each charge.

Most users give this grinder high marks, but this is not a tool designed or suitable for every job. Smaller jobs are where the DCG426B shines. Those who are looking for the right tool for larger or longer jobs would be better served looking elsewhere.

Overall, this is a quality grinder that can handle most tasks and offers excellent movement. If you need a cordless tool, this is the one to get.

Makita GD0601 Electric Die Grinder

  • Uses AC and DC power
  • Maximum speed of 25,000 RPM
  • 3.5-amp motor
  • Collet uses 1/4-inch bits
  • Weighs 3.6 pounds


  • A lower-power motor than many competitors’ models
  • Smaller size may be harder to use for those with larger hands
  • Warranty is only one year


Many people have good things to say about this grinder, but in our opinion, there wasn’t quite enough to get it over the hump to be chosen as one of our best picks.

The ability to power the GD0601 with either AC or DC electricity is very welcome and allows you to use this tool anywhere you need it.

At 3.5 amps, the motor on the GD0601 comes in below the power of other grinders, and well below the 6.4 amps of the Metabo GE710.

Make no mistake, this is still an excellent grinder. The Makita GD0601 packs a lot of power into its small size and is used happily by professionals everywhere.

Even though it’s not the Best Pick, this grinder is still a solid choice for an entry-level craftsman.

Makita GD0800C Heavy Duty Grinder

  • Uses AC power
  • Maximum speed of 25,000 RPM
  • 6.6-amp motor
  • Collet uses ¼-inch bits
  • Weighs 3.5 pounds


  • One of the most powerful motors available in a grinder
  • Includes built-in safety measures
  • Special double neck design helps with precision handling


  • Variable speed of motor not settable by user
  • Power of motor causes Rapid heating of grinder at times
  • Warranty is only one year


The second Makita grinder on our list comes in as the lowest of the two for several reasons.

While the GD0800C does have a variable-speed motor, the speed is controlled internally by the grinder itself, using the variation to provide a smooth power-up experience.

Once it’s up to speed, the 25,000 RPMs from this grinder will handle most smaller jobs with ease. However, some users have reported that this grinder can quickly heat up during use.

That said, the grinder can be forgiving to novice users who would otherwise damage it. The safety features keep you from destroying the motor and gears.

We can’t say this will be a great tool for everyone, but anyone looking for variable speed should find that this does the trick.

DeWALT DWE4887 Electric Die Grinder

  • Paddle switch for easy gripping
  • 25,000 RPM motor
  • 4.2-amp motor
  • Collet uses ¼-inch bits
  • Weighs 4.7 pounds


  • Works with either AC or DC power
  • Great power for the size and price
  • Built for accuracy


  • Not variable speed
  • A bit heavier than other options
  • Size of the tool makes it more difficult to use in tight areas


Coming into our testing process with many glowing reviews, the DeWALT DWE4887 certainly lives up to its reputation.

With a large amount of power compared to many other grinders in its class, the DWE4887 is capable of grinding through almost any material.

In fact, the sheer power this grinder puts in your hands was one of the main reasons it comes in as our Best Value. You won’t find a more powerful grinder at this price point.

Another feature that many users like is the fact that the collet and the collet nut are all one piece with the DWE4887. This aspect makes it faster and easier to change your fitting.

With the ability to run from regular household outlets, generator, or welding machine, the DWE4887 goes where you need it to with no hassles.

For anyone who is trying to find the perfect blend of affordability and power, this grinder comes out on top.

Is it worth buying a more expensive electric die grinder?

While you may be tempted to opt for a less expensive option when purchasing a new electric grinder, you need to keep in mind that the phrase “You get what you pay for” often applies with grinders.

While there are some quality options at lower price points, these tools will many times be of lower quality and have a shorter lifespan than a more expensive model.

This is not a hard and fast rule, however, as some expensive grinders don’t have the specs or performance to make them worth the purchase price.

Admittedly, your budget plays a part in your decision of electric grinder. However, saving a few dollars at the time of purchase might not make up for later costs like repair or replacement of a less expensive model.

Read all the reviews you can of the various models you’re interested in and take their recommendations into account when making your decision. Benefiting from the experience of others can help you avoid a “good deal” that turns into a costly misjudgment.

Buyer’s Guide

As you can see, there is a wide variety of features available on electric grinders, but just because they exist doesn’t mean they’re important to the work you want to do.

Let’s look at some of the more common features available and break down who might find each of those features useful.


While most people first look at the maximum RPMs of an electric grinder, there are a few things to remember before using this to guide your buying decision.

The RPM rating listed for a grinder is a “no-load” speed. This means that this is the maximum output the motor will produce while the grinder is spinning freely.

Torque is what determines the RPMs of a grinder while it’s in use. The higher the torque, the faster it will spin and the more power you’ll have when cutting, grinding or buffing.

Motor Protection

When the motor dies, your grinder is dead as well. Several things shorten the lifespan of your grinder’s motor, and some newer models have protections built into their design to help protect the internal components from these hazards.

Dust and heat from grinding can destroy the fan blades inside your grinder over time. This is a definite problem, as using a grinder for any length of time can produce an excessive amount of heat inside the tool.

makita, gd0600, corded, grinder

There are different safeguards being offered by tool manufacturers, including automatic shutoff circuitry to stop your grinder before the heat can cause lasting damage to the motor.

Also, there are new designs that offer varying degrees of protection to the motor from the dust and debris that is created while using your grinder.

Safety Features

The heat and debris generated from using an electric grinder present another potential problem, but not to the tool. These things can cause serious issues for the user if left unchecked, especially heat.

Of course, almost all grinders come with a wheel guard as part of their design. If the adjustment of this safety feature is awkward or difficult, some people decide to just leave it alone or remove it completely and hope for the best.

As you can imagine, “hope for the best” is not a good safety plan. When you’re looking into various safety features of grinders, look for wheel guards that can be adjusted without the use of additional tools.

We already covered the motor overheating in the last section, but this also plays a role in staying safe. Be sure your grinder will shut off in emergencies to prevent burns from overheating.

Consider what you will use the grinder for and look for safety features that fit this style of work.


Think about the scope of the projects you have in mind. How you plan on using the grinder should dictate the size of the tool you choose.

It can be tempting to buy the bigger, more powerful grinder that can tackle industrial tasks. However, when it comes to jobs at home or in your workshop, you may find that it is quite limiting.

For tricky angles or small areas, getting a compact, cordless grinder may do the trick. While these may offer less power, you will have more control over the project.

How is it powered?

This sounds like a simple question to answer, but there are several different types of power sources that electric grinders are designed to run on.

AC powered grinders can be plugged into any common household outlet, which would be handy for a DIY type of person. DC powered grinders can run from a direct hookup to a generator or welding machine, making them useful on site for professionals.

There are also now models on the market that can be powered by both, which gives these the versatility to be used almost anywhere.

If you want complete versatility, then cordless grinders powered by a battery could be your best choice.

Be sure to make sure the grinder you want to purchase has power requirements that will allow you to get the best use from your tool.


How powerful should the grinder I purchase be?

It depends. This may sound like a “cop-out” answer, but the truth is that not everyone needs the most powerful grinder available on the market. There are many different motor power levels for sale to fit various needs.

If you’re mainly going to use your grinder for smaller jobs, a less powerful, lightweight tool might be exactly what you need.

If the work you’re going to do with your grinder involves small spaces or harder-to-reach areas, you’ll want to look for grinders that are easy to manipulate.

Do I need variable speed control?

An electric grinder that features variable speed control to adjust the RPMs of the motor is useful when it comes to tackling different tasks and materials.

If you plan to use your grinder for just one type of job, then variable speed control may be of little use to you.

If you’re looking for flexibility in what you can do, then yes, variable speed control is a good option.

Is there a standard size for fittings? Do I need to make sure everything’s compatible?

Most people use 1/4-inch, or sometimes 1/8-inch, fittings, but there are those that are sized in millimeters instead of inches. This leads to a problem for some.

If the electric grinder you’re looking at purchasing is listed as using 1/4-inch fittings, you should be in good shape as far as easily finding what you need.

If your potential grinder uses any other size, it might be best to see how easy it will be to find fittings that are useable.

Will any grinder be able to do the job I need to do?

A: The short answer is no. The power of the motor and the RPMs it produces plays a large part in determining what materials an electric grinder can effectively tackle. Also, there are other features that can make a grinder a great fit or a bad idea for some jobs.

If you need an electric grinder to work in small spaces, a larger unit is going to make that more challenging than it must be. Likewise, there are some jobs that need more pure power than anything else. A smaller, more agile grinder might not cut it.

Again, your choice of grinder is best determined by the jobs you need to do.
