Abstract
A tool provided with a head tapering stepwise toward a front side. Each step of the head has a cylindrical area for calibrating a pipe end and, joining it, a conical area for deburring the pipe end. Each step of the head corresponds to a usual pipe size. When the head is pushed into a pipe end to be processed, the pipe end is first calibrated and subsequently deburred in one operation. The pipe end is centered in relation to the longitudinal axis of the head due to the calibration at the cylindrical area, which guarantees accurate deburring at the conical area. Each conical area has a plurality of cutting edges, which are formed by chip grooves. The tool is especially suitable for preparing pressed connections on composite pipes.
