The relationship between constancy in bur geometry and cutting effectiveness was established by using enamel substitute and simulation technics. A maximum in cutting behavior with an F57 carbide friction grip bur was found at 200,000 rpm and was related to the cutting process. Generally, a linear dulling rate was observed with a pronounced reduction of cutting effectiveness.
