Cutting Data

High P Grade Recommendation

A TiC/Al2O3 multilayer, CVD coated grade. Used for grooving and turning
IC5005
gray and nodular cast iron at medium to high cutting speeds.

Speed IC8150 A very hard substrate with a cobalt enriched layer, improved MTCVD TiCN and a thick alpha Al 2 O 3
CVD coating. Features excellent thermal stability, resistance to chipping and plastic deformation.
Recommended for high speed machining of steel at stable or slightly unstable conditions.

2
Excellent thermal stability and resistance to chipping and plastic deformation.
TP20 A hard substrate with a cobalt enriched layer, MTCVD TiCN and alpha Al O 3 CVD coating.
Recommended for high speed machining of steel at stable conditions.
A tough substrate with a cobalt enriched layer combined with improved MTCVD TiCN and a thick alpha
IC8250 Al O 3 CVD coating. Re׳commended for general use machining of steel in a wide range of conditions,
2
Low featuring high toughness and resistance to chipping and plastic deformation.
