A guide to understanding router bits - Carbitool
A router bit works by spinning at high speeds to cut, shape, and trim materials like wood. It acts like a chisel or plane blade, with a cutting edge or flute that removes material as it is guided along a path. Different bits are designed for specific tasks, such as creating straight grooves (straight bit), decorative edges (chamfer or roundover bit), or trimming one piece flush with another (flush-trim bit).
