Abstract
A rotary cutting tool includes a rotary tool body, a blade clamp, a cutting insert, a clamp fastener, and an insert fastener, wherein the rotary tool body has an insert pocket to define a bottom positioning face, a first lateral positioning face and a second lateral positioning face. The cutting insert is affixed to the blade clamp via the insert fastener. The first lateral positioning face is orientated opposite to a side cutting edge of the cutting insert. The blade clamp is slid into the insert pocket in an axial direction of the rotary tool body, wherein the blade clamp is coupled by the first and second lateral positioning faces in an interference clamping manner and is retained at the rotary tool body by the clamp fastener. The present invention has the advantages of strong radial impact resistance, high positioning accuracy, high safety concern and long service life.
