Mapal's new cutting material series for boring

Mapal has developed a CVD-coated cutting material series specially tailored to the demands of boring in all cast materials - GJL, GJV and GJS.

The new cutting materials HC720, HC725, HC730 and HC735 differ in the carbide substrate used in each case. All four impress with their extremely heat-resistant α-aluminium oxide coating with very good coating adhesion.

Cutting edges with the new coating offer the potential for a significant increase in the cutting speed during boring, even with dry machining.

Machining is easily possible with a cutting speed of 300 m/min, thus offering a considerable boost in productivity. At the same time, the cutting edges achieve significantly longer tool lives, as examples in practice show: when machining GJL25, the tool life was tripled compared with the PVD cutting material HP455 used to date.
