Bench grinders are remarkable pieces of equipment that help the consumer keep their tools and lawnmower blades nice and sharp. Of course, sharpening tools aren’t the only thing that the bench grinder is capable of doing. It’s also capable of grinding, cutting, removing rust, buffing pieces of metal, and even polishing metal pieces. That makes it a versatile tool for any home or professional workshop, and the primary reason why we wanted to review some of the best bench grinders available. And that’s precisely what we did. We reviewed three models that we thought provided exceptional quality and then paired it with a handy guide on what the consumer should look for when purchasing a new grinder.

Dewalt 8-Inch DW758 Grinder

 Editor’s Choice 

We’ve selected this bench grinder from Dewalt for a number of reasons. The first reason we selected this product was that it was designed and manufactured by Dewalt, a company that knows a thing or two about manufacturing high-quality tools. The second reason we’ve selected this model is that it delivers the power, reliability, and durability that people need for grinding or polishing metal or for sharpening tools. It’s a product that features a 3/4-HP induction motor that provides plenty of power for grinding applications and runs at 3,600 RPM that makes material removal quick and almost effortless.

This product also has a cast iron base and durable metal housing that ensures that this product is durable and will last the user a long time. It features aluminum tool rests that have been machines precisely for the delicate precision a person needs while they’re doing position work. And because this model has rear exhaust ports in the wheel guards, it’s capable of operating more smoothly than models that have to be regularly cleaned out.

This 8-inch grinder has 12.5-inches between the wheels that allow the consumer to grind larger objects and/or to grind longer than they would be able to with other bench grinders. This model also comes with 36 and 60-grit wheels, eye shields, spark deflectors, and operating instructions. This should be everything a person needs to get this grinder up and running so they can get their work done. And it’s for all of these reasons that we’ve selected this model as our favorite model of all of the bench grinders we’ve selected. Sure, it does cost more than the other two grinders we’ve reviewed, but it is a quality model that will do the work it needs to do and remain in operation for a long time. In the case of this grinder, the consumer gets what they pay for.

PROS:

  • This grinder’s motor runs at 3,400 RPMs.
  • It has a 3/4-HP induction motor.
  • Has rear exhaust ports that make it smoother to run.
CONS:

  • This grinder costs a little more than some other models.

WEN 4280 8-Inch Variable Speed Grinder With Work Light

 Also Recommended 

Another bench grinder that caught our attention was the WEN 4280 grinder. This is a 5-Amp grinder with an arbor size of 5/8-inch and a model that’s designed to handle a variety of DIY and industrial jobs. The first thing that we’d like to discuss this grinder is both one of its greatest positives and also one of its greatest drawbacks. This product features a variable speed motor that’s designed to work from 2,000 RPM to 3,400 RPM. This feature makes this machine very versatile but unfortunately, it doesn’t always work as well as we would’ve liked for one reason and one reason only.

If this grinder isn’t at its full 3,400 RPMs under load, then it can slow down or stall a bit. This only happens when a little bit more pressure is applied and while the unit isn’t a full-speed, but it is something to think about. Of course, the slower speed is mainly designed for more precision jobs while the higher speed is intended for material removal purposes, so it’s a slight problem that we can overlook.

One thing that we really liked about this grinder was how it was built. It was built with a sturdy cast iron base that had mounting holes that can be used to protect the unit from walking or wobbling. It also comes with a flexible work light that allows the consumer to keep their work illuminated at all times—a feature that should help with productivity. This machine also came with 80-grit and 36-grit grinding wheels so the consumer can use this machine right away. All of which makes this 16.5×10.5×16-inch machine the one that’s worth being mentioned and one that consumers might want to look at.

PROS:

  • This is a reasonably priced bench grinder.
  • It has a variable speed from 2000 to 3,600 RPMs.
  • It comes with a work light.
CONS:

  • The grinder can falter when not operating at full-speed.

Delta Power Tools Variable Speed Grinder

 Also Consider 

The last bench grinder we would like to review is this 6-inch model from Delta Power. Although this model features 6-inch wheels instead of 8-inch wheels, we still think that it’s a great model for DIY enthusiasts to use in their home workshops. This model is perfect for grinding, sharpening tools, and polishing metals. We just don’t feel that it’s large enough or powerful enough for industrial applications. Now that we’ve said that, let’s look at some of the features found on this machine that we think consumers will appreciate.

This model has an assembled height of 11-inches, a depth of 11-inches, and a width of 14.5-inches. It has two 6-inch wheels with a 1/2-inch shaft diameter and features a 2.5-Amp induction motor that provides a pretty good amount of power. It also features a variable speed that allows it to be run from 2,000 to 3,4000 RPMs. Speed can be easily selected using the dial that’s located on this unit’s front panel. This is also where the on/off switch for this unit. An on/off switch that has a safety feature that can be set so that the unit can’t be started.

This bench grinder also features a handy work light that helps to illuminate the projects the user happens to be working on. This product also comes with 36-grit and 60-grit wheels that are capable of handling a wide assortment of different jobs. This machine also has a 6-foot cord. It’s also worth mentioning that this machine also comes with four rubber feet to prevent the machine from “walking,” two safety-shields, and fully-adjustable tool rests. All of these features, as well as the ones we haven’t discussed, make this bench grinder one that some people are going to want to add to their garage or home workshop. It’s an inexpensive model that seems perfect for a variety of DIY jobs.

PROS:

  • This product comes with a handy work light.
  • This product has a variable speed of 2,000 to 3,400 RPMs.
  • This grinder has a powerful 5-Amp motor.
CONS:

  • It’s only a 6-inch bench grinder.

The Ultimate Guide To Bench Grinders

After familiarizing yourself with some of the best bench grinders we’ve reviewed, you might still have questions about these machines. Don’t worry, that’s completely normal. Not everyone is familiar with all of the features or even the benefits of using these machines. And that’s why we’ve decided to do a deep dive into the subject and talk about these machines in a little more depth. So, if you’ve wanted to learn a little more about these machines, then come along with us as we discuss them. 

The Top Uses For Bench Grinders

Many people look at bench grinders and then wonder what they could possibly use these machines for in their daily life. However, once a person begins to realize all of the things that can be done with these grinders, they quickly begin to realize that maybe they should buy one. Some people even go as far as to wonder how they have ever gotten along without one of them for so long. Now, let’s look at some of the things that bench grinders can do, shall we?

  • Sharpening metal objects
  • Sharpening tools
  • Buffing or polishing metal

A Bench Grinder Buying Guide

We will now turn our attention to some of the things that consumers should think about when purchasing a new bench grinder. These grinders come in a variety of different sizes and with a variety of different features, so it can sometimes feel difficult to choose one that suits you the best. Hopefully, this guide will help change that by helping you focus on the features that matter and ignore the rest. 

Choose A Bench Grinder Type

The first step to choosing the best bench grinder for your needs is to decide on whether you need a 6-inch or an 8-inch model. In common parlance, 6-inch models are often known as regular speed grinders and 8-inch models are considered professional models. Let’s examine each of these two types individually and find out where they shine.

6-Inch Grinders

These grinders generally have speeds under 3,600 RPMs, so they’re powerful enough to handle the needs of most people working at home. Most of these models are also quiet and are easy to use by DIY enthusiasts. 

8-Inch Grinders

These grinders have speeds above 3,400 RPMs and are large enough for professional use. These models are designed for people who need to do extensive work, so they’re not ideal for home use but work great for people who need to use a buffing wheel or some other professional application. 

Take A Look At The Base

The next thing that the consumer should consider is the base of the unit. Quality grinders are made with iron bases that provide a good foundation for the machine. Some of them also can be mounted to a workbench to prevent the machine from vibrating and to add additional stability to the machine. 

Consider The Speed Of The Motor

Another thing that the consumer is going to want to think about is the power of the motor. Bench grinder motors come in sizes from 2.5-Amps to 5-Amps. The higher the amperage on the motor the more horsepower the motor is going to have. This translates directly into more power. For DIY models, 2.5-Amps is more than sufficient, but for professional grinders, 5-Amp motors are the standard. 

Think About Variable Speed

When it comes to these types of grinders, some models have variable speed control and others do not. Variable speed control allows the consumer to slow down or speed up the grinding wheels as necessary. Models that don’t have variable speed control are either all the way off or all the way on. What you need the grinder for will determine if you need variable speed control. If you’re just removing excess material from metal or sharpening tools, you won’t need variable speed control, but if you’re doing some more precise like shaping material, then you might want to think about it. 

Additional Features To Think About

The above features are the ones that most people are going to want to think about when they’re choosing a new bench grinder, but there are additional features but there are a few additional features that we would like to talk about. The following feature extends the usefulness of bench grinders or gives the consumer the necessary tools to begin using their grinder immediately. 

  • Safety-shields
  • Rubberized feet to dampen vibrations
  • A work light
  • Wheels of different grits included
