Recommended Carbide Grades
Insert Grades AC805P / AC810P / AC820P / AC830P
Selection
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 T he 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.
AC820PIn 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.
AC830PIn addition to FF-TiCN, which has excellent peel-off and wear resistance, this grade features a
strengthened FF-Al2O3 layer using new stress control technology, and moreover provides excellent
reliability and wear- resistance in heavy interrupted cutting to achieve long tool life.
