Dec 15, 2000 Usually vitrified wheels are used at speeds less than 6,500 surface feet per minute. At higher speeds, the vitrified bond may break. Organic bond wheels are generally the choice between 6,500 and 9,500 surface feet per minute. Working at higher speeds usually requires specially designed wheels for high speed grinding.When it comes to sharpening chisels, as opposed to shaping, a metal edge, a low rpm grinder offers a lot of advantages. There are uses for high speed grinders too, but it’s very important to understand the applications and differences between each machine.
