Abstract: The present invention provides a cutting head of a reamer. At least two wiping pads extend rearwardly from a cutting head forward end. At least one cutting section comprises a cutting edge that extends from the cutting head forward end to the peripheral surface. The cutting edge is formed at the intersection of a rake surface and a relief surface. The rake surface is generally tangentially directed and faces a direction of rotation. A deflecting surface is formed adjacent the rake surface and generally transverse thereto. The deflecting surface extends from a rake surface first end in a direction away from the cutting edge. The deflecting surface makes an acute axial angle with respect to the axis of rotation. A rear end of the deflecting surface joins the peripheral surface adjacent the cutting section and distal the rear end of the cutting head.

Abstract: A rotary cutting tool comprises a cutting head which is axially secured to a forward end of a shank by a locking screw. At least one radially extending locking wing of the locking screw is located in at least one radial recess of the cutting head or at least one radially extending passage is formed between the locking screw and the cutting head.

Abstract: A cutting tool has a cutting head which is removably secured to an adaptor of a tool holder. Upon replacement of the cutting head the adaptor remains fixed in the tool holder. In addition to the adaptor, the cutting tool includes a shank in which the adaptor may be retained, and a retaining element configured to form a sub-assembly with the adaptor without being threadingly engaged thereto. The retaining element is positioned and configured to limit rotation of the adaptor about a longitudinal axis of the tool.
