What are the most important factors to consider when choosing the best angle grinder? Size, rpm, and motor are usually the main important things to consider. Most common angle grinders are at 4.5 inches in size, and they are intended for low to medium duty tasks. They are very easy to control and use at home or in shops. Large ones, which are usually at 7 inches in size, are for professionals who need to utilize both of their hands for operation and control.
