Top 7 Best Bench Grinders On The Market 2019 Reviews

If you believe that “Do it once, do it right” is the mantra of a true craftsman, then you are a candidate for a high-quality bench grinder.

We promise that once you add this versatile and precision tool to your workbench, you will forget the days of second rate results when tool sharpening, honing, cleaning, polishing, grinding down welds, removing paint, and lots of other tasks we need to get done.

What Are The Most Important Features In The Best Bench Grinders?

We will be looking at horsepower, vibration, wheel size, arbor size, grinding wheel composition, and other factors that will ultimately decide your overall satisfaction with this important tool.

Wheel Types

There are four types of wheels and brushes we can use on our bench grinder. And, all the models we will compare today will be delivered with two types of stone wheels.

On one side, will be a rough stone that is used for repair work, often “the first pass” when taking down the edges of old worn out tools, getting the dings out of lawnmower blades, grinding down welds, and other aggressive grinding tasks.

The second wheel is made of a much finer grinding material and is ideal for the “final finish” on projects and is “the final pass” to sharpen chisels, shape woodworking tools, and put a high-quality professional finish on projects.

While the best bench grinders we review will include two grinding wheels, none are delivered with a wire wheel for cleaning off rust and paint, or a soft cloth wheel used for polishing. Those are handy additions that many folks add to the “get it done” toolbox, and can really solve problems around the shop quickly.

Let’s Grind Away At The Facts And Get To The Finer Points…

(Sorry, we could not resist that one.)

Before we get started, think about this.

Most grinders have either a 6-inch or an 8-inch wheel, but, most people never stop to really think this through in terms of performance and results.

Let’s imagine a 6-inch wheel and an 8-inch wheel are glued together. Let’s put a piece of tape across both to keep track of RPM. That tape is flying by at the same time on both wheels, right? Are they going to grind material at the same rate? The short answer is “no.”

But Why?

The word of the day is “circumference.” Do you remember this one? The circumference is the distance around a circle. So let’s see what the difference is. The circumference of a 6-inch wheel is 18.84 inches. The circumference of an 8-inch wheel is 25.12 inches. In every revolution, the 8-inch wheel is 6.28 inches “longer!”

That is an extra foot of grinding surface for every two revolutions, so that big wheel is going to tear through the material much faster at the same RPM. Fair enough, but there are several trade-offs in that story.

It will take a lot more horsepower to turn a bigger wheel, which is more prone to exaggerate vibration if out of round or not balanced. Lastly, for folks using the bench grinder to sharpen chisels and hone woodworking tools, the extra “length” of the bigger wheels means higher heat buildup in less time.

Craftsmen who rely on super sharp tools know that once the tip of the tool is overheated, it reduces tool performance in a meaningful way.

So, don’t forget to pay attention to wheel size and RPM when you make your final buying decision!

One Last Thing!

These Grinders have powerful motors, and therefore, large motor casings. In some models, the casing gets in the way. In other words, if you put a straight edge across both wheels, it would also touch the motor casing.

This makes it very difficult to work on long items like lawn mower blades, machetes, sickles, scythes, and other cutting tools.

So. let’s look at what’s available and find the Best Bench Grinder…

Top 10 Best Bench Grinders For The Money 2019 Reviews


1 DEWALT DW756 6-Inch Bench Grinder

We just talked about the difference in performance in 6-inch versus 8-inch grinding wheels, so we want to start with this 6-inch Bench Grinder from Dewalt.

Dewalt is a very well-known brand, and most professional contractors agree that in many tool groups, they set quality standards. They are a leader in terms of warranty with their 3-year limited warranty, one year of free service, and most importantly, offer a 90-day money back guarantee.

This cast iron body is painted with the signature “Dewalt” bright yellow paint. (That paint also helps cover the rough casting that Chinese parts sometimes have.)

A large plastic horizontal on-off switch…

We would like to mention that Dewalt Bench Grinders feature a large plastic horizontal on-off switch. Traditionally, the switch on a bench grinder is a simple metal up and down toggle switch nested in a narrow guard.

Both are good, we were just interested in this design change and wonder which switch is most likely to turn on accidentally if it is bumped into.

This is an example where the motor casing gets in the way. In other words, if you put a straight edge across both wheels, it would also touch the motor casing. This makes it very difficult to work on long items like lawn mower blades, machetes, sickles, scythes, and other cutting tools.

Warranty – 3-year limited warranty, 1 year of free service, and most importantly, offers a 90-day money back guarantee.

2 JET 577102 JBG-8A 8-Inch Bench Grinder

The Jet Bench Grinder is a true “old school” quality tool. It is definitely a professional grade option for those who want this to be the last bench grinder they purchase.

It sits on a robust cast iron foundation, and features cast iron wheel guards and dust vents. And to ensure a quiet and smooth performance, the unit comes with rubber mounts. Of course, there are holes provided for permanent mounting, which is something most users elect to do.

The grinding wheels are driven by a 1 horsepower, 1 phase, 115-volt motor that is a beast you will not find slowing down, even in aggressive grinding applications.

The “secret sauce’ in this workhorse is the marriage of their enclosed pre-lubricated ball bearings spinning industrial quality grinding wheels. When you shut it off, they just keep spinning for a surprisingly long time!

This excellent tool receives very high reviews by both the DIY crowd and shop professionals.

3 RIKON Professional Power Tools 8” Slow Speed Bench Grinder, 80-805

We talked about wheel size and RPMs and the tradeoff we accept with either choice. Here we see an 8-inch slow speed grinder with 1-inch wide white aluminum oxide wheels. (8in – 60 grit and 120 grit)

A slow turning grinder is often the choice for craftsmen whose primary interest is tool shaping and sharpening. When tools are applied to fast turning wheels, they heat up very quickly, which may have a negative effect on the strength and durability of edges. So a slow turning wheel offers better control and reduces the chance of overheating the metal.

The tool rest on the left side has a special groove for fast and easy sharpening of drill bits.

This unit includes a nice diamond wheel dressing tool, to make your grinding wheels turn smoothly and with the correct face properties.

Our rating:4.3 out of 5 stars (4.3 / 5)

  • Great design.
  • Spark guards are on long arms and easy to adjust.
  • Compact.
Cons
  • Can not do aggressive shop work.

Dewalt is a very well-known brand, and many professional contractors agree that they set quality standards. They are also a leader in terms of warranty with a 3-year limited warranty, one year of free service, as well as, offering a 90-day money back guarantee.

This cast iron body, as usual, is painted with the signature “Dewalt” bright yellow paint.

As with the previous Dewalt grinder we reviewed, we would like to mention that Dewalt Bench Grinders feature a large plastic horizontal on-off switch. Traditionally, the switch on a bench grinder is a simple metal up and down toggle switch nested in a narrow guard. Both are good, we were just interested in this design change and wonder which switch is most likely to turn on accidentally if it is bumped into.

5 SKIL 3380-01 6-Inch Bench Grinder

The price and size of this 6-inch grinder should be the first clue that this is purely a DIY shop tool. It is limited to small jobs like sharpening and polishing scissors, knives, chisels, and lawn mower blades.

One of our pet peeves with all 6-inch bench grinders is the fact that the width of the motor is either equal to, or very close to the diameter of the grinding wheels. If you put a straight edge from wheel to wheel, there is a good chance you are hitting the motor.

This makes it a problem to work with longer items.

Low noise and vibration…

That being said, this bench grinder is a good fit for lots of people who do occasional small jobs. At only 20 pounds, it is very portable, and the rubber feet on the bottom help it stay in place and minimize noise and vibration.

We like the clever LED lights that are incorporated into the eye guards that other brands do not offer.

It is a very compact design, so does not need a lot of valuable workbench space.

It spins two grinding wheels at 3,450 RPM, but with even moderate pressure, will slow to a crawl, so once again think “smaller jobs.”

SKIL 3380-01 6-Inch Bench Grinder
Our rating:4.2 out of 5 stars (4.2 / 5)

Pros
  • Small, smooth and quiet.
  • Extremely portable.
  • LED lights incorporated into the eye guards.
  • Quick and easy to get up and running.
Cons
  • The Motor may deliver 3,450 RPM, but there is no torque to back that up. With moderate pressure, this is brought to a “grinding halt.”
  • LED lights incorporated in the eye shields are not adjustable.

6 WEN 4276 2.1-Amp 6-Inch Bench Grinder with Flexible Work Light

Like all 6-inch grinders, this unit is really a DIY solution, and has little value in a heavy duty pro shop. It is limited to small jobs like sharpening scissors, knives, chisels, and lawn mower blades.

That being said, this bench grinder is a good fit for lots of people who do small jobs. At only 16 pounds, it is very portable, and the rubber feet on the bottom help it stay in place and minimize noise and vibration.

We like the traditional gooseneck fully adjustable light, which makes this a real standout over other brands.

It is a very compact design, so does not need a lot of valuable workbench space.

The 1/3 HP – 2.1 Amp / 110 Volt motor spins at 3,450 RPM, but with even moderate pressure, will slow to a crawl, so once again think “smaller jobs.”

WEN 4276 2.1-Amp 6-Inch Bench Grinder with Flexible Work Light
Our rating:4.2 out of 5 stars (4.2 / 5)

Pros
  • User-friendly with that fully adjustable light.
  • Small, smooth, quiet and, vibration free.
  • Extremely portable.
  • Quick and easy to get this unit up and running.
Cons
  • A great light, but ships without a bulb.
  • No holes to allow bolting it down.
  • Uses a lot of plastic parts.
  • Cannot hold up to much pressure while grinding.
  • Not well suited to run for long periods.

7 POWERTEC BGSS801 Slow Speed Bench Grinder, 8″

This slow speed bench grinder design is best suited for sharpening projects. Like its peers in the slow speed bench grinding universe, it should not be counted on for really aggressive grinding projects that require fast turning high torque motors.

The ½ horsepower motor is quiet and turns the grinding wheels at a “cool” 1,725 RPM.

The white aluminum oxide wheels are 1 inch wide for easy sharpening performance.

The motor features a locking on/off switch to prohibit unauthorized use, which is especially nice around curious kids investigating your workshop.

POWERTEC BGSS801 Slow Speed Bench Grinder, 8
Our rating:4 out of 5 stars (4 / 5)

Pros
  • Slow speed grinders provide more control when shaping and sharpening tools.
  • 8-inch white aluminum oxide wheels generate less heat to prevent bluing and heat degradation on cutting tools.
  • Distinctive locking power switch that keeps unauthorized users, and curious kids, out of harm’s way.
  • Does not overheat quickly, and has less vibration.
Cons
  • The indented tool tray for drill bit grinding is higher on one side than the other, causing the working surface to be very small for other sharpening tasks.
  • The steel washers on the wheels are out of center in some cases, and sometimes a bit warped.
  • The 8-inch white aluminum oxide wheels are too soft and develop ruts easily. They are often out of true, resulting in meaningful vibration causing inconstant results.

So Many Choices Of The Best Bench Grinder, Where To Begin?

We have covered a lot of ground in this study of the best bench grinders and have discovered three basic classes:

  • 6-inch Bench Grinders.
  • Slow speed Bench Grinders.
  • All-purpose high-speed 8-inch industrial grade Bench Grinders.

We feel that whether you are a DIY weekend warrior, or a dedicated full time professional, you deserve a rugged all-purpose machine that will answer the call regardless of the task you throw at it.

The reality is that “yes” a slow speed grinder controls heat. But, do you know what else controls heat? A light touch and a pot full of water to dip the tool in.

And “yes” the little 6-inch grinder does not take up much room, and you can carry it around. Does that happen a lot, carrying your bench grinder around? You will not miss that little extra space a full-sized bench grinder takes, because will you will get so much more use out of it.

Lastly, the increased wheel size in an 8-inch model means the grinding wheels will last a significantly longer time without replacement.
