Abstract
A machining tool (1) includes a band-shaped tooth supporting body (2) and a plurality of teeth (3) each having a tooth tip (4) being covered with cutting particles (5) to form a plurality of geometrically undefined cutting portions. The tooth tip (4) is furthermore covered with buffer particles (6) of a different material than the cutting particles (5). The buffer particles (6) are located between the cutting particles (5).
Claims8
A method for producing a cutting tool comprising the steps of:
- coating a portion of a tooth tip of a tooth with cutting particles to form a plurality of geometrically undefined cutting edges;
- coating a portion of the tooth tip of the tooth with buffer particles having a circular cross-sectional shape and being made of a different material than the cutting particles in such a way that the buffer particles are located between cutting particles;
- and
- removing the buffer particles so that free spaces are defined between the cutting particles.
