Abstract
A rotary cutting tool for processing a metal workpiece includes an elongated solid body composed of cemented carbide containing cobalt. The body has cutting edge means at its forward end and an axis of rotation therethrough. The body has a surface of which cobalt content is greater than that of the remainder of the body. Part of the surface of the body is ground to remove the cobalt-rich surface therefrom.
