Router bits are mostly used for machining wood. However, due to their carbide cutting edges they are also very well suitable for working on other kinds of materials like plastics.
The router bits are available as different types for chamfering or bevelling, for milling slots, characters and concave or convex radii, and for surface milling. The Orange Tools TM are manufactured by CMT, an experienced specialist for woodworking tools. The paint serves also as non-stick coating to prevent that resins and impurities may accumulate at the cutting edge.
