WEN 4276 6-Inch Bench Grinder – Well-Designed and Lightweight Machine

WEN isn’t far from new in the business of developing power tools. Founded way back in 1951, the company has shown its ingenuity when it comes to conducting research relevant to creating modern tools. With pioneering contributions in the form of chainsaws, electric jigsaws, and even wet wheel sharpeners, WEN has consistently demonstrated its strength as a manufacturer.

Right off the bat, we liked the simple yet pleasing appearance of the WEN 4276 6-inch grinder. Our WEN 6-inch bench grinder review revealed quite a lot of things.

Sporting only black and orange, this WEN bench grinder evoked minimalism and quality performance. At only six inches, this bench grinder will easily fit in any workshop. Despite the relatively lightweight of 17.70 pounds, the package provides what you’ll generally need: a 60-grit wheel and a 36-grit wheel.

The former is usually used for sharpening chisels while the latter generally deals with common gardening tools. The WEN 4276 bench grinder does not offer an 80-grit or 100-grit wheel, but that’s fine since these wheels are barely used by most people.

One of the practical features we recommend is the eye guards.

We all know that sharpening tools and shaping metals can lead to nasty, unwarranted sparks, so this part of the bench grinder helps keep our vision safe. And speaking of vision, WEN was smart enough to add a work light. This means that we had an extra source of illumination to prevent inaccuracies when grinding tools.

The fact that the work light is flexible is another bonus. Additionally, the adjustable tool rest of the WEN 4276 6-inch bench grinder further improved our accuracy.

Another winning design choice from WEN is this bench grinder’s wheel guard. Unlike other bench grinders with wheel guards that are hard to remove, this one allows for quick wheel changes.

As for the warranty, WEN is gracious enough to provide a two-year warranty. Since the company is quite big, they have a pretty reliable customer hotline and even a national service network.

As soon as we used the WEN 4276 bench grinder, we realized how nice it was for this machine to include a 2.1 amp motor that wasn’t irritatingly loud.

Not only did it keep things relatively quiet for the operation but the amp motor also meant we didn’t have to wait long for startups. In fact, the grinding process was smooth from start to finish. With a power of 3450 RPM, we noticed that the WEN 4276 bench grinder had enough speed and consistency.

However, this quiet process is also caused by the fact that this bench grinder is not as formidable as the bigger machines. It’s great that it is lightweight and more portable than the other grinders, but these characters have prevented the WEN 4276 bench grinder from being a solid first choice for grinding.

This might not be great for heavy-duty use, but it’s still one of the best bench grinders for basic purposes.

Furthermore, getting rid of rust wasn’t much of a problem. WEN really did a swell job of picking only the most durable and reliable materials for manufacturing this bench grinder. The WEN 4276 bench grinder also complemented the relative quietness of the 2.1 amp motor with a cast iron base.

Essentially, the mounting holes of the base improve the stability of the machine during usage.

What We Liked

  • Beautiful design and relatively light
  • Grinding process is quiet, smooth, and precise
  • Wheel guard and tool rest are easy to adjust
  • Works great as a buffer

What We Didn’t Like

  • Not powerful enough for heavy duty use

DeWalt DW758 8-Inch Bench Grinder – Formidable and Loaded with Features

DeWalt has long been in the power tools industry and with the DW758 8-inch bench grinder, it seems that the company has once again proven why they deserve to be among the giants in the industry. In fact, there are no other 8-inch bench grinder reviews except for this.

With a plethora of features, this was clearly meant to be the best bench grinder of DeWalt, and they have a great color combination of black and yellow.

We like this color choice, as it looks professional and made for industrial applications. The DW758 bench grinder also has an aluminum tool rests to keep users in the right position. We didn’t feel like they were just there as a gimmick since these tool rests are actually precision-machined sections of the machine.

Similarly, the spark deflectors here are sizable enough to prevent us from panicking about sudden combustion.

As for the wheel guards of the DeWalt bench grinder, we commend the inclusion of rear exhaust ports. Not everyone will notice the benefits, but these ports keep the sharpening operation running smoothly.

In addition, the DeWalt 8-inch bench grinder has enough space between its wheels for two significant purposes: wheel size and duration.

Thanks to the 12-1/2-inch distance, you can switch the wheels for bigger variants with ease while also enabling more strenuous grinding operations. Still, we would’ve appreciated it if the DW758 bench grinder offered more than just the standard 36 grit wheel and 60 grit wheel.

If you ever have problems with this bench grinder, you can use the limited warranty that lasts for a whopping three years. Likewise, DeWalt offers one full year of free service and a 90-day money-back guarantee. The company is obviously confident you won’t return it, and we don’t blame them.

The DW758 machine is a legitimately impressive product in terms of design and quality of the materials alone.

The DW758 bench grinder does not aim to be quiet – it aims to be as powerful as possible. Then again, we also didn’t find the noise irritating; the vibrations weren’t always overbearing.

The only exception to the otherwise flawless process is once we’ve used the 36 grit wheel several times. Initially, it did a swell job, but it began to cause more noticeable vibrations. In turn, these vibrations affected the bearings of the DW758 machine. In other words, more friction was created and affected the otherwise smooth operations.

Once we noticed this, we sought a new grit wheel of the same size to prevent affecting the overall lifespan of the bench grinder. Thankfully, the 60 grit wheel didn’t have this problem. The DW758 has a rather premium price, so it shouldn’t hurt if DeWalt provided a much better 36 grit wheel.

After all, this grinder houses an impressive 4.2-amp motor. This machine boasts of a 3,600 RPM, and we truly felt its force as it effortlessly dealt with materials.

Furthermore, this will last you for quite some time.

The motor housing is incredibly tough and the cast iron base is as rugged as it can be. DeWalt definitely paid attention to this bench grinder’s durability. All in all, the DeWalt DW758 is a formidable bench grinder with a remarkable 3,600 RPM.

While the 36 grit wheel loses its flare after prolonged use, all the other parts of the machine are durable and reliable. From the spark deflectors to the precision-machined tool rests, this bench grinder delivers accuracy, safety, and sheer performance.

What We Liked

  • Aluminum tool rests are sizable and maintain accuracy
  • 4.2-amp motor and 3,600 RPM ensures powerful grinding operations
  • Rugged iron base and motor housing
  • Sharpening basic tools takes only minutes

What We Didn’t Like

  • 36 grit wheel not as durable as expected

TruePower 199 Mini Multi-Purpose Bench Grinder – Excellent Basic Functions

Unlike WEN and DeWalt, TruePower isn’t exactly a household name when it comes to power tools. Still, the release of the TruePower 199 bench grinder might just change that.

In terms of color, the TruePower 199 bench grinder is similar to DeWalt with its black and yellow combo. This bench grinder utilizes a 150W high-speed motor.

In particular, this motor is rated at 110 volts. This isn’t exactly impressive when compared to bigger bench grinders, but this is suitable enough for a small machine like it.

Thanks to its size, we had no trouble finding a place to use it; the workbench could readily accommodate the TruePower 199 bench grinder.

As for speed, it goes from 0 to 10,000 RPM. This amount might make you think it will do its job faster than the entire bench grinders included here, but its small size means that it cannot compete in terms of sheer force.

Then again, the TruePower 199 bench grinder is supposed to be for casual operations only. The package includes an instruction manual, collet wrench, hex wrench, a 31-inch flex shaft attachment, a 3-inch grinding wheel, and even a 3-inch fiber polishing wheel.

This machine is quite affordable, so it’s really nice that two wrenches and two wheels for different functions are part of the package. To elaborate, you will appreciate the inclusion of the collet wrench if you constantly have to tighten slotted colors in differently sized collet knobs.

On the other hand, a hex wrench is primarily created for driving bolts and screws that contain hexagonal sockets. Just like the other bench grinders, the TruePower 199 machine has a safety guard and a tool rest.

This is a basic and lightweight bench grinder, so we accepted the fact that this won’t compete with the DeWalt machine in terms of heavy-duty use.

One of the best things about this kind of bench grinder is how quiet the whole process was during our first attempts. The power is good for taking care of your usual tools and workpieces.

We highly advise you to utilize the attachment piece to keep your work as comfortable as possible. For those of us who had the tendency to stop sharpening workpieces several times, the lower speed settings were basically a godsend.

If you are not in a hurry and you want to be careful, you should use this bench grinder at a relatively slower speed.

Speaking of speed, we noticed that it was a bit slow at reaching the desired speed. We had to turn the knob almost halfway before the wheels started rotating as fast as we wanted.

Moreover, we had to adjust the speed knob carefully as it looked like it could be accidentally removed at any moment. Still, the grinding process is remarkable on its own, right once a decent speed is achieved.

In general, the TruePower 199 is an impressive, small bench grinder that casual users will appreciate.

What We Liked

  • Lightweight
  • Contains two wrenches and wheels
  • Grinding process is quiet and smooth
  • Reliable safety guard and tool rest

What We Didn’t Like

  • Speed knob not very durable
  • Reaching desired speed takes a bit of time

Sunex Tools 6-Inch Bench Grinder with Light – Formidable and All-Around Impressive

Our fourth entry is another six-inch bench grinder. This time, the machine is manufactured by Sunex, which has steadily grown its presence in the industry for four decades. With the Sunex Tools 6-inch Bench Grinder with Light, the brand has once again displayed its innovative flair as it aims to have the best bench grinder of 2021.

This Sunex Tools bench grinder has a largely red tone and a sturdy appearance. The shine of the central section is pretty nice. One of the things we immediately noticed is the relatively big work light. These days, an additional source of light does a lot more than people give it credit for.

As for the included wheels, the Sunex Tools 6-Inch bench grinder offers the usual 36 grit wheel and the 60 grit wheel. What we found admirable, however, is the quality of these grit wheels.

Furthermore, each of these wheels has a spark guard to protect you from sparks that could cause a fire. This machine also has an eye shield that you could adjust whenever you like. For those of us who want a bench grinder in a permanent area, this Sunex Tools grinder already has mounting holes.

It’s easy to mount the Sunex Tools bench grinder on any pedestal with little to no modifications needed whatsoever. There are also some nifty rubber feet for additional stability even when the sharpening process is leading to many vibrations. Thus, we didn’t find any inconveniences whenever we mounted this bench grinder on a stand or on a workbench.

Even the cast iron base is built for heavy-duty use. We don’t mind its rather substantial weight of 29.5 pounds. Not only are the materials excellent, but the features work together to maintain the quality.

The Sunex Tools 6-inch bench grinder has a formidable 3.5 amp motor and has a ½ HP motor for power. Likewise, the no-load speed of this machine is at 3450 RPM. This isn’t different from the others that are also worthy of being called the best bench grinder, but we noticed that there is something special about the Sunex Tools grinder.

Those of us who’ve been using grinders for most of their lives for their farm and ranch equipment admitted that using this one was a blast.

It doesn’t start quickly, but reaching the full speed only takes seconds. In addition, the wheel support’s slot on the right side allows you to sharpen drill bits.

One thing we didn’t particularly like is how it took some time to change wheels due to the small space for our fingers to move around in. Tinkering with the bolts and nuts wasn’t exactly ideal for those with huge hands. Other than that, the wire wheel is a triumph.

Throughout the operations, the motor has been generally quiet without losing its power. This might just be the best bench grinder for sharpening.

Grinding a couple of angle irons was pleasant as the Sunex Tools 6-inch bench grinder didn’t move around too much and disrupted its placement on the workbench. Moreover, this machine was more than capable of removing rust and sharpening mower blades and other home equipment.

It seemed like Sunex Tools covered all the bench grinder uses to please individuals who wanted to know what to look for in a bench grinder.

With this 6-inch bench grinder, Sunex Tools has definitely captured our attention. It’s incredibly durable and sturdy – complete with the features you would want from a bench grinder.

What We Liked

  • Extremely durable build
  • Flexible work light
  • Full speed is achieved within seconds
  • Great overall performance

What We Didn’t Like

  • Changing wheels might take time for some users

Palmgren 6-Inch Bench Grinder – Smooth Operation and Great Design

Our final pick for the best bench grinder is from Palmgren. Just like most of the entries here, the Palmgren grinder measures six inches. With many products similar to it, the Palmgren six-inch machine had to offer something different to rise from the competition.

The 27-pound Palmgren six-inch grinder primarily uses black, and we like it.

The look is simple, but this dark color allows users to locate the bright section at the center even more. In addition, this bench grinder was made through high-precision steel construction.

To complement the one-piece steel construction, Palmgren also utilized chrome-plated steel screws.

Moreover, the grinder promises to ease the setting of small angles with the standard gage block sets. The Palmgren bench grinder also paid extra attention to the eye shields as they are not only adjustable but also positioned using hurricane bolts.

Likewise, the tool rests are fairly sizable and are also adjustable. Aside from the thick cast aluminum wheel covers, the six-inch bench grinder also contains a rather slim motor casing.

The only minor gripes we have with this bench grinder are that the power switch doesn’t look durable and that the instruction manual wasn’t as helpful as expected.

The illustrations of the screws and the tool rest, for example, didn’t really resemble the actual machine. Other than that, the Palmgren grinder is wonderful in terms of the package and design. If you ever found the machine to be underperforming, you should be happy to know that there is a two-year warranty.

An advantage the Palmgren bench grinder has over others is its superb bearings. While other grinders are quite unbearable during operations, this machine offers a smooth and relatively quiet performance. Yes, there are still some vibrations, but they are kept to a minimum. Even when we’ve turned off the power, the wheel would still spin for a while because of the great bearings.

In relation to this, the speeds can be adjusted from 2000RPM to 3300 RPM. Of course, we also decided to test the maximum speed of 3450RPM by using the click. The switch from one speed to another is fairly quick, and the torque is decent regardless of the chosen speed.

With each burring and polishing we conducted, this bench grinder was stable. The wide base really helped, so much so that the machine wouldn’t move too much even if it wasn’t mounted.

Overall, there is a lot to be admired here. The only hiccups are the instruction manual and the flimsy power switch.

What We Liked

  • High-precision steel construction
  • Adjustable eye shields
  • Smooth operation
  • Great design enhances stability

What We Didn’t Like

  • Instruction manual needs improvement


All of these bench grinder reviews delighted us with their performance and design, but only one machine can stand at the top. However, before we identify the number one bench grinder, we would like to recommend the DeWalt DW758 8-inch bench grinder. If you are looking for the best 8” bench grinder, this is what you should get.

It’s powerful with a 3,600 RPM, and it does its job with precision.

However, we think that the Sunex Tools 6-inch bench grinder with light deserves the utmost recognition. Not only is it remarkably durable but it also has many things you’ll love, such as the adjustable work light and the drilling holes.

Most importantly, its performance is fantastic and full speed is attained within seconds. With that, we believe that the Sunex Tools 6-inch machine is the best bench grinder there is.

Now that you’ve read the best bench grinder, take the time to read about the best rotary tool. It is better to have options.
