10 Best Bench Grinders of 2021 Compared & Reviewed

Best Bench Grinder

A bench grinder is a benchtop tool, mostly electric-powered, which rotates abrasive wheels at very high speed to sharpen your dull tools.

This type of grinder is especially recommended for its ability to handle a wide range of tools that specialized grinders can’t. You can sharpen tools, deburr them, remove rust from tools, shape, and even clean different objects.

You can get a 6-inch or 8-inch grinder depending on the projects you require it for. For home and DIY projects, a 6-inch grinder is enough. Professionals may prefer 8-inch ones for their industrial application.

To learn what grinder to get for your grinding needs and budget, dive into our top 10 bench grinder reviews and buying guide.

What To Check Before Buying Best Bench Grinder?

How to Buy the Best Bench Grinder

1. 6-inch or 8-inch Bench Grinder

Bench grinders tend to fall within two major categories: 6-inch, and 8-inch grinders. 6-inch wheel grinders tend to have regular speeds while 8-inch wheel ones can have low speeds.

6-inch bench grinders have their motors rotating at regular speeds. They may have motors producing power in the 2-4-ampere range, with RPM levels of around 3,400-3,600.

These grinders produce enough power to execute the most basic grinding, especially for home improvement tasks.

8-inch grinders, on the other hand, are designed for professional use. Heavy-duty grinding tasks, for instance, on an industrial scale, are best served by an 8-inch grinder.

Due to the increased size over 6-inch grinders, 8-inch ones tend to require fewer wheel changes. You will be doing less maintenance if you own such a grinder.

2. Types of wheel

Choosing the right kind of wheel for your grinder will make your work easier. The most common types of wheels include:

Straight: They are ideal for surface grinding. These wheels are the most common in bench grinders and are ideal for sharpening chisels. They also come in multiple sizes.

Cylinder: They are also known as hollow wheels. They work best with vertical or horizontal bench grinders. It’s worth noting that cylinder wheel grinder can sometimes prove to be large and heavy.

Tapered: This type of wheel is ideal for grinding gear teeth or threads. They are specialized wheels designed for use on specialized grinding tasks.

3. Speed

From the models we reviewed, bench grinders can have either constant speed or variable speed motors. You may notice that constant-speed grinders are the most common.

If you are a home or DIY users, a constant-speed drill is ideal for you because it is straightforward to the user and fixed speed will be ideal for all your domestic grinding needs.

Any grinder running a constant speed of at least 3000 RPM is more than enough for you.

Since professionals and commercial workshops may require grinders for different tasks, they are best served by variable-speed grinders.

For example, you may own a grinder with a speed of 2,000 – 3,450 RPM. You can use the lower speeds to polishing and buffing metals, while the higher speeds can be used for sharpening.

4. Weight

Weight is an important consideration when buying your bench grinders. As our reviews showed, some models we consider lightweight weigh less than 20 pounds while the heavier ones can weigh over 30 pounds.

Generally, heavier bench grinders tend to have more features than lighter ones. For example, 8-inch grinders have larger grinding wheels than 6-inch ones. Hence, an 8-inch grinder may be heavier, but the extra weight is justified by superior features.

A grinder’s weight may have an impact on its stability, and vibration-redaction capabilities. Heavier grinders tend to be more stable than lighter ones during operation. However, the lighter grinders may be easier to transport than heavier ones.

5. Extra Features

There are many extra features that come with bench grinders to add value to these tools or enhance their capacity for safe operations.

We recommend getting a grinder that prioritizes user safety with features such as adjustable spark guards for preventing sparks from meeting your body, and adjustable eye shields for preventing metal shavings from entering the eyes.

Dust vents are also important extra features, which can help channel metallic dust away from you and the grinder.

Other useful features we identified, which can transform your experience when using the tool, are the mounting hole on the device’s base. These holes are very useful when you want to mount the grinder on a bench or any other surface especially if you’re a professional who has a workshop.

Finally, for stability, rubber feet are useful features to have on your grinder for they help reduce vibration during operation.

6. Budget

There are bench grinder models available for both budget, and premium buyers. The good news is that you can get high-quality grinders for both categories of pricing.

Heavy-duty and professional grinders may be more costly because of their industrial build quality and extra features such as large grinding wheels. However, such high prices tend to be justified by the high performance of such tools.

Low-budget bench grinders also tend to be of excellent quality, especially for domestic and DIY projects. Hence, if you’re into home improvement and related projects, you can still own a decent grinder without paying a premium for it.
