Abstract: A method for manufacturing a cutting tool (10) with lubrication orifices of complex shapes, including the steps of: producing a polymer insert (20), overmoulding a body of the cutting tool (10) with the polymer insert (20) by injecting into a mould, removing the polymer insert (20), so as to form in the body of the cutting tool (10) lubrication orifices, the shape whereof is complementary with that of a part of the insert (20), machining the body of the cutting tool (10) on an active part thereof, and depositing an abrasive coating on a surface of the active part of the body of the cutting tool (10).

Abstract: The machining tool is used for grinding a workpiece in a machine tool. The tool includes at least a first machining portion having particles of a harder material than the material of the workpiece to be machined, the particles being arranged in a binder, and at least a second machining portion having particles of smaller diameter than the first machining portion, and of a harder material than the material of the workpiece to be machined, the particles of the second portion being arranged in an identical binder to that of the first portion or in a different binder.
