Please try to choose an operation indoor environment and wear protective guards and goggles.
Never exceed the recommended maximum permitted rotational speed for safety reasons.
In order to have a good stock removal rate, quality of surface, and thermal loading on the workpiece, the best performance would be with a recommended cutting speed of 15-20m/s.
Don't push and increase the pressure during the processing to achieve a finner surface looking, but try to switch to different grit flap wheels.
The clamping length between shank and grinders should be more than 15mm.
Never exceed the maximum safe speed when the shank is extra long. Try to consult your sales to check the safety rotating speed before use.
