Abstract

A rotary material removing tool whose holder can be installed in and rotated by a milling or like machine. The front portion of the holder has a transverse slot flanked by two prongs and receiving a portion of a flat cutter which is held in the slot by one or more coupling screws in such a way that its rear surface is urged against the bottom surface in the slot. The coupling screw is received in a bore of one of the prongs and its head extends into a bore of the cutter. The peripheral surface of the head and/or the surface surrounding the corresponding portion of the bore in the cutter is conical, and the two surfaces cooperate to urge the rear surface of the cutter against the bottom surface in the slot when the screw is driven home. To this end, the axis of the bore which receives the shank of the screw is disposed between the axis of the bore in the cutter and the bottom surface in the slot.
