Steel P Representative Grades /

Performance

Covers a range of machining applications from high speed to interrupted cutting and small product machining. AC810P ： In addition to FF-TiCN, which has excellent peel-off and wear resistance, this grade features a tough, thick Alumina coating enhanced by newly developed grain growth control technology, excellent wear resistance and long tool life in high-speed, high-feed cutting. AC8025P： Employs Absotech Platinum, a new CVD coating. This grade has excellent adhesion and chipping resistance thanks to a

smooth surface treatment and reduction in tensile stress within the coating layer to achieve a stable, and long tool life. AC830P ： In addition to FF-TiCN, which has excellent peel-off and wear resistance, this grade features a strengthened FF-Al O layer using new stress 2 3 control technology, and moreover provides excellent reliability and wear- resistance in heavy interrupted cutting to achieve long tool life.

AC1030U： Employs Absotech Bronze, a new PVD coating, and exclusive tough carbide substrate. This grade reduces

adhesion and microchipping with a high-quality cutting edge to achieve excellent machined surface quality.
