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).
