Also, define where you need the grinder (home, garage, or workshop) and the length of time necessary.
From the reviews above, there are distinct bench grinders for separate needs. If you require a grinder for lighter tasks like sharpening, then you go for a grinder with a lower RPM. However, a bench grinder with a higher RPM is what one requires for buffering. If you want your grinder to serve multiple purposes, you ought to get one that offers variable speeds.
Define Your Budget
Review your budget for purchasing a bench grinder. This will enable you to narrow down your choices and as well give you the right items to focus on.
Also, defining your budget helps you to understand the kind of job you need your equipment to perform. You’ll further determine whether you need a more powerful bench grinder and/or one that does/does not have variable speed.
Some good quality bench grinders available for a lower price including the WEN 4276 2.1-Amp 6-Inch Bench Grinder with Flexible Work Light and the DEWALT Bench Grinder, 6-Inch (DW756). Other lesser-known brands may also offer quality bench grinders on a lower budget.
The need for protection in your workroom is imperative and indisputable. Always ensure that any bench grinder you choose has safety tools. If you recall, we emphasized the need for safety, and all the bench grinders recommended have safety eye shields and other safety tools.
On your side, always ensure you put on your safety gear before commencing any work on your bench grinder.
The wheels are among the essential parts of the bench grinder. Before you decide on any bench grinder, understand the type of wheel it offers. We highly suggest that you get a grinder that offers more than one wheel option.
Wheel options could be a coarse, fine, or medium wheel, and they carry along with either vitrified aluminum oxide (for grinding steel) or silicon carbide (for cast iron and nonferrous materials).
Identifying your needs, as stated above, also helps in choosing a wheel option.
Another aspect to look out for before purchase is the overall speed of the bench grinder. The higher the rate, the sooner you get your work is done, which is precisely what you need to get more job done.
We advise going for a bench grinder with at least 3000 to 3600 revolutions per minute. There are also variable speed choices that you to alternate between high and low power.
To properly get the work done, you need to observe all the angles of your work. A work light provides you with enough light to do your job even when it is dark.
It is, therefore, imperative that a workbench comes with a work light. Note that some work lights are adjustable and may be connected directly over the center of the bench grinder, while others may be built into it or located over the wheels. Some grinders also possess more than one light attached, and this makes it easier for you to see what you’re doing from all angles of the grinder.
Bench grinders come in different sizes and shapes. While making a buying decision, consider the enormity of the work, you would require your grinder to perform. Your choice of size wheels will be informed by it. You could opt for a more giant-size wheel or a smaller one; it all depends on your preference.
Before you venture out to the equipment market, first understand your need for a bench grinder and choose one that guarantees your safety and as well gets the work done efficiently and effectively.
With this in mind, we highly approve of the Dewalt brands. They are known for their durability and high performance. Also, their products come with a three-year warranty, which is considered fair. Nonetheless, we consider the Wen 4276 6-Inch Bench Grinder to be the best product on this list.
