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.
Claims17
A tool for chip removing machining comprising a drill and a countersinker mounted thereto, the countersinker having at least one insert seat for receiving a cutting insert for chip removing machining, said drill defining an axis of rotation and provided with at least one chip flute extending in a generally axial direction of the drill to form a chip-removal channel, the countersinker including a connection portion received in the chip flute and configured with a form generally corresponding to that of the chip flute, wherein the connection portion is form-locked to the chip flute.
A countersinker adapted to be mounted on a drill for chip removing machining, the countersinker having at least one insert seat for receiving a cutting insert, the countersinker including a connection portion configured with a form generally corresponding to a flute of a drill to establish a form-locked connection with the drill, the countersinker comprising two sections adapted to be clamped together and to the drill.
