The wheel size or the grinding wheel size of any bench grinder is the simplest, yet the essential thing to consider before buying one. This is due to the reason that different bench grinders have various sizes that make them ideal and useful for different kinds of applications and usage.

Its diameter in inches gives the size of the grinding wheel. It includes options like 6 inch and 8-inch abrasive wheels, where the larger size is generally considered to be the better one. A larger wheel size allows you to grind larger objects and surfaces quite quickly.

Just like any other electrical power tool, the motor power of a bench grinder is mentioned in amps that include options like 2.1 amps or 4.1 amps. When compared with each other, the higher power rating of 4.1 amps offers better performance to the user for grinding.

Motor Speed

Another way to get an idea of the performance offered by a given bench grinder is to check its motor rotation speed. As you can expect from its name, the motor speed simply tells you the number of times the motor or the grinding wheel of a given bench grinder rotates every minute. This motor rotation speed rating is generally given in RPM or rounds per minute.

Usually, bench grinders come with a variable speed trigger that allows you to quickly and precisely change this motor speed as per your requirement.

Similarly, any bench grinder that comes with a single grinding wheel takes up less space in your workshop and may be a good fit for your welding bench or table.

Durability and Reliability

You should also check the durability and reliability of a bench grinder to ensure that it can easily last for a long time. The easiest way to check the strength of a given bench grinder is to look for its build quality. Any mill that uses cast iron for its base is usually highly stable and sturdy. You can also check the warranty duration offered by a given bench grinder.
