Abstract

A drill tip screw (3) for fastening of a drill tip (2) to an exchangeable head drill support body (1) has a general extension in an axial direction (10). The drill tip screw comprises a screw head (12) at a first axial end (11) of the drill tip screw and an outer threading (18) at a second axial end (19) of the drill tip screw. The second axial end is opposite to the first axial end. The drill tip screw further comprises a center portion (15), wherein the center portion is rotationally symmetric. The drill tip screw further comprises a first tapered portion (14) having its widest end (21) connected in one piece to the center portion. The first tapered portion is rotationally symmetric. An axial cross-section of the first tapered portion presents a concave surface shape.
