Front Angles and Cutting Geometries

4 standard lead angles are available: Carbide Grades
Lead L [inch] Use IC07 grade is the basic substrate for reaming inserts.
Higher surface quality, lower cutting It is a very versatile submicron grade. IC07 features
conditions (not recommended very 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 .118 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
conditions. Can be used on iron (K) workpiece material group.
