Abstract

A titanium-nitride coated carbide cutting tool is formed with complex angularly intersecting surfaces which form cutting edges having a generally trapezoidal configuration. The tool creates fine thread-like grooves in a circumferential wall of a tube which may be employed as a heat pipe. The generally trapezoidal resulting groove increases groove surface area that in turn increases working fluid wicking action.
