Abstract: A rotary cutting tool includes a cutter of generally cylindrical shape disposed about a central longitudinal axis. The cutter has a first end having an active fluted portion and an opposite second end, the second end having a male threaded portion disposed thereabout. The cutting tool further includes a shank of generally cylindrical shape disposed about the central longitudinal axis, the shank having a recessed female threaded portion formed in a first end. The male threaded portion includes a number of threads disposed at a first pitch and the female threaded portion includes a number of threads disposed at a second pitch different than the first pitch. The cutter and the shank are selectively coupled via threaded engagement of the male threaded portion and the female threaded portion.

Abstract: A rotary cutting tool including a cutter member having an axial forward end and an axial rearward end. A cutting region is at the axial forward end of the cutter member, and a male threaded portion is adjacent the axial rearward end of the cutter member. A shank member has an axial forward end and a shank bore opening at the axial forward end. The shank bore has an axial shank bore length. The shank bore contains a female threaded portion and an axial rearward shank bore portion axially rearward of the female threaded portion. The axial rearward shank bore portion has a terminal end. When the male threaded portion of the cutter member fully engages the female threaded portion of the shank member, the axial rearward end of the cutter member being spaced a first distance axially forward of the terminal end of the axial rearward shank bore portion.
