Abstract
A tool body having a longitudinal body axis has a central body recess recessed in a rear body surface thereof. The recess includes an inner recess surface, and a body recess peripheral surface extending between the inner recess surface and the rear body surface. An integral central pin extends rearwardly from the inner recess surface, and having an integral pin length measured along the longitudinal body axis from the inner recess surface to a rear pin surface thereof. In a circumferential direction about the longitudinal body axis, the body recess peripheral surface alternatingly increases and decreases in distance from the longitudinal body axis, thereby forming a plurality of angularly spaced apart longitudinal axis crests. A tool holder has a protrusion with complementary surfaces to engage the tool body. A fastening member, such as a lock nut, secures the tool body to the tool holder to form a cutting tool.
