Abstract
The T-slot milling cutter disclosed employs an indexable insert having two alternative edge surfaces which serve alternatively as the rake face and rear abutting face of the insert which transfers the cutting force to the rear wall of the insert pocket of the cutter. The alternative edge surfaces comprise three facets, once central to the surface and the other two receding from the central facet at equal angles thereto. They serve primarily to wedge the insert into mating angular surfaces in the rear wall of the insert pocket to secure the insert against dislodgement when held in the pocket by the customary attaching screw and, by their obliquity to the cutting direction, improve the cutting action when serving as the rake face.
