A bench grinder can be used for many different tasks, but all of these involve the use of a grinding wheel to sharpen, remove rust or perform maintenance on various tools.

Best Bench Grinders For Locksmith Business

Naturally, the quality of a bench grinder is essential for the sharpening to be as good as possible. This makes finding the best bench grinder a crucial task for anyone who works with razor-sharp tools which need to be at their very best most of the time.

The quality of a bench grinder is heavily correlated to the quality of the grinding wheel that it works with. The most common types of bench grinders operate with 6 or 8-inch wheels (Source).

Although these devices seem to be nothing more than a simple motor with a couple of spindles, good quality bench grinders don’t go unnoticed, professionally speaking.

There’s also a major difference between finding a great bench grinder and finding the best bench grinder to suit your needs.

Best Bench Grinders 2019

1. DEWALT DW756 6-Inch Bench Grinder – Best Overall

The brand is definitely the first thing that catches the eye when looking at this product for the first time. Dewalt is a great tool manufacturer.


As a consequence of this, whoever purchases this product is almost guaranteed to have high expectations and demand top-notch performances from their bench grinder.

We’ll be as direct as we can with what we’re going to say: this is one of the best bench grinders that you can find. If quality isn’t enough to convince you, let us make things better: the product is also very affordable – since Dewalt manufactures it in China, the device is considerably cheaper than other products of similar quality being sold in American stores.

To be clear, the DW756 is affordable when it comes to high-end bench grinders. You might find other cheaper options, but their quality is very likely noticeable when compared to a device such as this one.

The grinder comes with a very strong and durable iron cast base, which almost guarantees a long lifespan for the product. This bench grinder’s motor leaves nothing to be desired either – it’s resistant, powerful and incredibly durable.

Another great benefit offered by the DW756 that shouldn’t go unnoticed is its ease of use. This bench grinder can be used by both amateurs and pros alike, although assembling the tool might prove to be a bit more difficult if you haven’t done anything like it in the past. Nevertheless, once the assembly process is out of the way you’ll be set with a tool guaranteed to last for a long time.

If there’s one thing that we’re iffy about, it has to be the design. Although the model looks very nice on its own, sharpening certain tools like mower blades could be troublesome as a consequence of the shape of the bench grinder.


  • Incredible value for money
  • Can be easily used by veterans and amateurs alike
  • High-quality built tool and grinding wheels
  • Can withstand a lot of use without any issue
  • Very powerful device capable of working with the most difficult tools

2. JET 577102 JBG-8A 8-Inch Bench Grinder – Best 8-Inch Bench Grinder

JET’s 577102 model is easily one of the fastest bench grinders that you can get for a relatively moderate price.


It can easily sharpen or remove rust from tools incredibly quickly – it has a powerful motor with 1 horsepower.

Speaking of which, the motor comes into full speed in nothing more than a couple of seconds. This bench grinder is not only fast when it comes to the speed in which it improves and sharpens equipment, though. The device can be used to its maximum effective a few seconds after being turned on.

Paying attention to small details is very important when you’re shopping for a new bench grinder, and we’d like you to take a look at the small spark protectors placed above the grinding wheels in this product. These small transparent screens are usually included with most bench grinders, but these ones are very conveniently placed and can be moved to suit your needs. Its size is very user-friendly, too.

One major issue that some bench grinders tend to have is that the motor slows down when you place a tool against its grinding wheels. Thankfully, the 577102 keeps going at the same speed, as if you weren’t even using. The grinder also doesn’t vibrate – this helps you work well with it without losing the grip of whatever tool you’re sharpening or cleaning.

Another thing to be noted from this grinder is the quality of each of its parts. They are well manufactured and none of them feel like cheap pieces put there to save the manufacturer some money. It works and feels like a very reliable tool. All you need to do is buy the tool, mount it and everything’s just ready to go.


  • One of the most powerful bench grinders that you can get online
  • Doesn’t get slowed down easily
  • Can grind heavy tools without inconveniences arising
  • Stays steady when in use, avoiding uncomfortable vibrations
  • Very sturdily built


  • Some people might find the guarding a bit poor
  • There were some shipping issues where the product arrived damaged. They seem to be resolved, though

3. WEN 4276 2.1-Amp 6-Inch Bench Grinder with Flexible Work Light – Best on Budget

Alright, you’ve probably arrived at the most versatile bench grinder review of this list. The 4276 has a bunch of different features, and most of them can be easily adjusted to better suit the needs of the user.


For example, the tool rest and the protective eye guards can be moved around a lot and they can be adjusted without any issues.

The main selling point of this bench grinder is its price, though. A good bench grinder often goes for a pretty important sum of money, but this one offers great quality at one of the most affordable prices on the market. If you’re looking for a cheaper option that won’t break down after just a few uses, you might want to take a more in-depth look at this product.

Its base is also very strong and made to be used for heavy duty work. The bench grinder also comes with a working light attached on top of it. This does wonders for those who need to use the grinder in a not-so-bright area. Precision is crucial in this type of work, and the light helps you attain a better level of illumination.

This grinder takes a bit longer to power up than others, but it still gets to full speed in less than 10 seconds, so this isn’t much of an issue. Setting up the device is a pretty straightforward process as well – you should be done in a few minutes, even after attaching additional features such as the spark protectors.


  • Includes a light, which facilitates work and improves precision
  • One of the best budget bench grinders that you can find
  • Made to be used as a heavy-duty tool
  • Has a solid base
  • Works pretty quickly


  • It isn’t as powerful as other bench grinders
  • Takes an above average amount of time to properly power up

4. Porter-Cable PCB575BG 8″ Variable Speed Grinder with Work Lamp – Best Variable Speed

The powerful PCB575BG is a variable speed bench grinder which can be easily adjusted. Depending on what you’re doing with the grinder, you can change the speed at which the device operates so it performs its task better.


For example, if you want to sharpen a tool, you might want to use a different speed than you’d use if you were removing rust or buffing it.

This grinder also includes a lamp, just like the 4276. The light itself is very powerful, but the lamp’s stick isn’t as sturdy. This causes the light to flop around when the grinder is set to full speed. If you’re buying the product strictly for the fact that it comes with a light, you might want to consider the 4276 instead – some people might even opt to remove the light from the PCB given the issues that it has.

The bench grinder comes with a very powerful motor which very much suits a product with variable speeds. The motor is packed inside a strong build, which looks good and feels good when using it. Contrary to what many might think, the motor doesn’t make much noise at all. It’s actually a very quiet tool, ideal for those who hate noisy equipment.

Vibration is also a huge plus when purchasing this product, in the sense that it’s very rare for the product to vibrate at all. It’s very solid and doesn’t move on its own when in use.


  • Adjustable power and lockable power switch
  • The product is sturdy and should last for a long time
  • The grinding wheels are fully and easily changeable
  • Well-designed spark protectors
  • Doesn’t make a lot of noise


  • The light is essentially useless
  • The tool rests aren’t well-designed. They can feel small depending on the tool that you’re sharpening

5. SKIL 3380-01 6-Inch Bench Grinder – Best 6-Inch Grinder

This 6-inch bench grinder comes with a very good set of features that make it an overall good option to consider, even if you’re new to grinding or know very little of the craft.


This bench grinder isn’t as expensive as others are, but still manages to hold its own when compared to other expensive products that you can find online.

The amount of noise that this product makes can be easily compared to the PCB. The device works very quietly when considering its powerful motor. Another important feature is that it comes with rubber at the bottom – if you don’t have any type of workbench in which to place the device, it still manages to stay still in one place when using it thanks to the way that it’s designed.

Keep in mind that you might still want to bolt it somewhere with screws if you intend to use this device for heavy-duty activities. The rubber is good and makes the product feel sturdier, but heavy equipment might still make it move if not properly screwed down. If you’re going to use this device simply for sharpening small tools, you’ll be glad to know it can sit on most tops without any issues.

After you unpack it, the device can be easily mounted and doesn’t require a long setup before it’s ready to use.


  • Comes almost entirely assembled
  • Good enough to be used in regular countertops if you’re not going to sharpen heavy-duty equipment
  • Doesn’t vibrate too much
  • It’s not really expensive but still manages to give high-end options a run for their money
  • Comes with clear instructions
  • Although the engine isn’t adjustable, it is very powerful


  • Tool rests are too narrow
  • Although this bench grinder does its job, you might find more powerful options in a similar price range

What to Consider Before Purchasing a Bench Grinder

Bench grinders are made for very specific purposes, but each one has different features that might work better for some tasks.

For example, if you intend to use a grinder for heavy equipment, you might want to consider a product with wide tool rests.

Or, if you want to use your grinder on a day-to-day basis, you might want to get yourself a bench grinder with variable speed and good durability.

In any case, we’re going to let you know which are the most important features that a bench grinder has, so you can better select a product adjusted to your own needs.

Power & Performance

Naturally the most important aspects of a bench grinder, power and performance are the two features responsible of making or breaking a top-quality bench grinder.

A well manufactured grinder should be able to perform regardless of the type of tool used with it. Power and performance are correlated with one another – both features need to be present in a quality grinder.

Tool rest quality

Those small supports placed alongside each grinding wheel are actually incredibly important.

A proper tool rest should have the capacity to support most types of equipment while also having enough resistance to withstand heavy-duty work.

If you want to use your bench grinder to work with big tools, you’ll need to find a device with wide enough tool rests.

Grinding wheel quality

All of the products that we reviewed today come with very good grinding wheels. These wheels are usually easy to change and people tend to buy new ones from time to time.

In any case, it is important that those wheels that come with the bench grinder offer good enough quality so the product can be used as soon as possible.


If the product is manufactured using solid components and strong materials, durability shouldn’t be an issue at all.

Some of the bench grinders that we’ve reviewed today might have a couple of flaws, but all of them are incredibly durable and shouldn’t break down even after years of use.

Revolutions per minute (RPM)

We’re telling you about the importance of RPM in case you’re thinking about getting some new grinding wheels to replace those included with your new bench grinder.

Wheels have a set RPM capacity which can be found in their labels – this capacity should never be exceeded by the bench grinder or it can cause the wheels to blow up.

Our Final Take

We’ve come a long way since we first started talking about bench grinders.

By now you probably already now how important it is to fully understand what you intend to do with your bench grinder as well as all of its features before.

Don’t worry, buying one of these tools isn’t really that difficult – just take everything that we told you into account and you should be all set.

We know everyone has their own needs and not every single bench grinder on this list might suit you, but we’ve shown you the best options that you have in each grinding category.
