  • classical mechanics - Why do dental drills need such

    2020-10-26 · Dental enamel is a hard material so the drill needs to exert a large force on it in order to break it. The force is proportional to both the drill radius (r) and it angular frequency (omega, rpm), simply because the speed of the drill material at the interface is v=omega r. So you could go for large r and moderate omega as for concrete. However dental repair requires narrow holes.
