The input of pneumatic angle grinders is presented in terms of CFM (cubic feet per minute) and there is typically a corresponding pressure in pounds per square inch (PSI). Speed of the Wheels and Discs Woodcutting discs typically feature a toothed, circular blade. You will notice the tips are often tungsten carbide.
