Coated Grades for Steel Turning AC8115P/AC8020P/AC8025P/AC8035P
█ AC8115P Cutting Performance High-speed Machining AC8115P
Amazing Wear Resistance Crystal Orientation Control Ultra-fine Alumina Layer
Crater damage is suppressed and tool life extended through improved alumina layer coating strength and higher carbide substrate plastic deformation resistance
█ AC8115P Cutting Performance (Conditions Same as Conventional) Wear resistance 1.5x through improved plastic deformation resistance
