Abstract
In order to allow high-precision machining of the inner surface of a pipe using little machining time, the draw broach has a cutting part having a plurality of cutters extending in the axial draw direction. The cutting part is divided into a main part and an insertion part tapering conically in the draw direction. The insertion part in turn is divided into a front region, viewed in the draw direction, forming a pre-cutting stage, and a rear region, wherein the conicity of the pre-cutting stage is less than that of the rear region.
