Buying Guide for a Cordless Angle Grinder

Disc Size

The disc is an important part of an angle grinder, and you should consider the size of the disc if you are buying it. The angle grinder has disc sizes available in many forms, ranging from the common 4 inches to the 9 inches in size. The size of the disc or the head of an angle grinder determines the size of the parts that it’s going to cut.

For common works, an angle grinder with less than 7 inches of disc size will be enough. For cutting a larger surface or large depth, you should opt for a larger disc in your grinder. Likewise, a pneumatic angle grinder works better for precision grinding jobs. You should also know that depending upon the motor power, the size of the disc in an angle grinder varies.

A typical angle grinder has a speed of anywhere between 5000 to 10000 revolutions per minute.
