Perfect interplay

MAPAL presents the two new HP016 and HP018 cutting materials for reaming and fine boring high-alloyed and stainless steels, cast steel and hardened steel. Cutting material HP016 is suitable for all machining operations involving a slightly interrupted cut, while cutting material HP018 is used for a continuous cut. Both are based on a silicon-doped PVD coating on two different varieties of carbides with low cobalt content, making them extremely resistant to wear and offering great dimensional accuracy.

The PVD coating has a fine crystalline microstructure, combining high levels of hardness and ductility. The cutting material is thermally very stable and offers impressive high-temperature stability and coating adhesion. To create an optimum surface in through bores and blind bores, the PVD coating is deposited in the μm range. This ensures the cutting edges retain their sharpness.

The new cutting materials are used for market launch in the reamers in the MN series by MAPAL, among others. These tools represent the utmost accuracy and are now ideally suitable for use in hard reaming as well as reaming stainless steel thanks to the new cutting materials. They operate according to the MAPAL principle – with a cutting edge and a guide pad opposite. Depending on the application, they are made from carbide, cermet or PCD.
