ABSTRACT:
A roughing cutter has a generally cylindrical shank with a plurality of lands and angular flutes separating the lands. A plurality of straight-crested cutting teeth are formed on the lands with radial relief. Each tooth has a straight cutting edge generally perpendicular to the radial direction. The orientation of the cutting edge permits it to be in parallel relationship to a surface of a workpiece while in cutting engagement. This results in a smoother finish than would otherwise be possible. The teeth of the roughing cutter may be cut by an axially advancing milling cutter with a sloping cutting edge.
