Abstract
A tool such as a drill or end mill has a central portion formed of a relatively tough hard material connected to an outer peripheral portion formed of relatively wear resistant hard material, i.e., the outer peripheral portion is more brittle and wear resistant than the central portion. The chip flutes of the tool are disposed only in the outer peripheral portion and thus are formed entirely of relatively wear resistant hard material.
