The AC6030M insert incorporates Sumitomo's Absotech Platinum, a newly developed CVD boride-based titanium compound for the outer layer of its five stage, multi-layer coating structure. This higher strength, smooth coating helps to prevent insert chipping, giving a resistance more than double that achieved with conventional coatings, says the company.
AC6040M has the benefit of the Absotech Bronze TiAlSiN coating. This multi-layer PVD coating is said to exhibit excellent heat and oxidation resistance, together with higher adhesion strength and good resistance to peeling-off.
The inserts are available in negative square, triangular, 35° diamond and trigon, while the positive series cover 35°, 55° and 80° diamond, square and triangular types.
