Grades

AC800P Series covers a wide range of machining applications from high speed to interrupted cutting. l All grades feature Super FF Coat, which has excellent wear and chipping resistance. l Versatile GE Type chipbreaker suited to high-feed applications. High efficiency, long tool life.

AC805P:The ultra-thick alumina coating achieves excellent wear resistance at high speed cutting above 300 m/min
under dry cutting conditions.
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.
AC820P:In addition to FF-TiCN, which has excellent peel-off and wear resistance, this grade features a high-

density structured FF-Al2O3 layer using new smooth surface treatment technology, and also employs coating thickness control technology to achieve excellent versatility, stability, and long tool life. AC8025P: Employs Absotech Platinum, a new CVD coating. This grade has excellent adhesion and chipping resistance thanks to the smooth surface treatment and reduction in tensile stress of the coating to

achieve a stable, 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 control technology, and moreover provides excellent 2 3 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.
