PCD cutting insert
MAPAL

With PCD the variety of different grades is far smaller than with PCBN, which makes selection easier. The grades differ mainly in their microstructure, in other words in the size of the diamond particles. MAPAL offers a carefully chosen selection of tried and tested grades which are best suited to high accuracy, efficient cutting.

In particular for materials producing long chips, such as aluminium wrought alloys with low Si content for example, MAPAL offers cutting edges with chipbreaker structures. Two different tried and tested structures are available as standard, with one structure specifically for controlled chip fracturing in precision machining and one for machining with greater cutting depths. The chips are compressed and broken without the structure being jammed and without build-up on the cutting edges.
