Front Angles and Cutting Geometries

4 standard lead angles are available: Carbide Grades

LeadL [mm]Use IC07 grade is the basic substrate for reaming inserts.
Higher surface quality, lower cuttingIt is a very versatile submicron grade. IC07 features
conditions (not recommendedvery high fracture toughness and wear resistance,
for nonferrous materials)which is required for efficient high speed reaming.
An uncoated IC07 can be used for machining

A 3 15˚ 3˚ L nonferrous (N type material group) applications.

Two types of standard coatings are available:

  • IC907 – a TiAlN PVD coating for steel (P) and stainless steel (M) workpiece material groups

Universal use, high speed cutting IC507 - a TiCN+TiN PVD coating for cast iron (K) conditions. Can be used on workpiece material group. a wide range of materials The following grades can be provided on request: L

B 1.3 PCD grade for machining aluminum

30˚ 3˚ PCBN grade for machining cast iron

  • IC30N (cermet) for machining steel
