Abstract
A tool for chip removing machining includes a drill and a countersinker mounted thereto. The countersinker comprises two half-sections that are clamped to each other and to the drill. The drill includes helical flutes defining respective chip-removal channels. Each half-section includes a connection portion received in a respective flute of the drill. The connection portion has a shape generally corresponding to that of the chip flute, so as to be form-locked within the flute. Each connection portion includes a convex surface facing the flute, and a concave surface facing away from the convex portion. The convex surface can be pressed against the concave wall of the flute, whereby the concave surface forms a section of a wall of a respective chip-removal channel.
