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. 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 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 L The following grades can be provided on request: B 1.3 • PCD grade for machining aluminum 30˚ 3˚ • PCBN grade for machining cast iron • IC30N (cermet) for machining steel Suitable for aluminum and brass at high cutting speed L C 0.55 75˚ When needed for blind hole - lower feed 30˚ D(1) 0.6 3˚ L (1) On request 3 standard cutting angles are available: Angle [deg.] Use 0˚ 00 For cast iron applications 6˚ 06 General use 12˚ 12 For stainless steel and aluminum 338 ISCAR
