REAMERS USER GUIDE

Front Angles and Cutting Geometries

4 standard lead angles are available: Carbide Grades

Lead L [mm] Use IC07 grade is the basic substrate for reaming inserts.
It is a very versatile submicron grade. IC07 features
Higher surface quality, lower cutting very high fracture toughness and wear resistance,
conditions (not recommended which is required for efficient high speed reaming.
for nonferrous materials) An uncoated IC07 can be used for machining
nonferrous (N type material group) applications.
A3 15˚ 3˚ L Two types of standard coatings are available:

Universal use, high speed cutting • IC907 – a TiAlN PVD coating for steel (P) and
conditions. Can be used on stainless steel (M) workpiece material groups
a wide range of materials
• IC507 - a TiCN+TiN PVD coating for cast iron (K)
B 1.3 L workpiece material group.
