ABSTRACT:
A shaping-and-cutting broach comprising cutting and gauging teeth and a shaping element located before the cutting teeth, said shaping element provided with projections on its surface which contacts the machined surface. Owing to said projections each cutting tooth has a continuous cutting edge and this, in turn, increases the strength of the tool as a whole and reduces the cost of its manufacture and operation.
