To be honest, this grinder is for a machine shop. The motor will be too fast to sharpen chisels and plane blades – you will burn the steel and loose hardness. Had one, gave it away and bought a variable speed 8” Delta and always use it on the slowest speed unless I am buffing something or grinding a lawnmower blade.

New Delta is like $30-40.
