PVD Coated Inserts Speed Up Machining Stainless Steel


Due to PVD aluminum oxide coating and high temperature wear resistance, Tiger·tec Silver PVD inserts speed up some small steel (ISO-P) components in mass production, and for difficult ISO-M and ISO-S machining. The latter materials are poor thermal conductors, so the resistance leads to longer tool life, higher cutting speed capability. 

Three positive geometries are available:  FM4 for finishing operations, MM4 for universal use including both 7° and 11° positive rake, and RM4 for roughing operations.


  • PVD aluminum oxide coating
  • Surface smoothing on the rake face reduces friction, heat
  • Lower PVD layer thicknesses, very sharp cutting edges are maintained for a soft cutting action or low cutting forces
  • FM4: finishing operations
  • MM4: universal use including both 7° and 11° positive rake
  • RM4: roughing operations.
