MAPAL has now introduced its new OptiMill-3D series of solid carbide milling cutters for the tool and mould making industry. With extremely heat-resistant coatings and special carbide substrates, the tools are characterised by the dimensions and geometries specially adapted to mould making.

Suitable for machining from 45 to 66HRc, the OptiMill–3D-HF-Hardened is available with four or six cutting edges and has two variants for high feed milling on challenging materials. The four-flute tool is the primary choice for roughing and pre-finishing. With fewer cutting edges and a wider chip gullet, rapid and reliable removal of swarf is ensured.

For roughing and pre-finishing, the 6-flute series produces the best surface finishes and flatness, and with a PVD coating, the tool dissipates heat generation to ensure tool life is prolonged. Available from 6 to 16mm diameter the OptiMill-3D-HF-Hardened is complemented by the three and four flute OptiMill-3D-HF for softer material machining.
