Sumitomo’s AC8025P Grade for steel turning is designed to achieve high productivity and a long tool life. Featuring Sumitomo’s own Absotech Platinum CVD Coating, combined with a tough carbide substrate, the AC8025P is designed to provide cutting edge chipping resistance and adhesion resistance. The coating adhesion strength help control residual stress and provide more than twice the chipping resistance as compared with conventional coatings, while maintaining wear resistance, the company says.

A smooth surface treatment is said to improve adhesion resistance along the ridgeline of the cutting edge. When machining low-carbon steel, rolled steel and other materials prone to adhesion, where problems such as peeling or chipping of the coating layer at the cutting edge, deterioration of the surface finish and reduced tool life may occur, the AC8025P increases tool life. According to the company, excellent edge sharpness greatly reduces chattering.

The AC8025P grade is suitable for a variety of steel turning applications, including continuous cutting, light interrupted cutting and interrupted cutting.
