USER GUIDE Front Angles and Cutting Geometries 4 standard lead angles are available: REAMERS Lead L [mm] Use 15˚ 3˚ L Higher surface quality, lower cutting conditions A 3 (not recommended for nonferrous materials) L B 1.3 30˚ 3˚ Universal use, high speed cutting conditions Can be used on a wide range of materials L 75˚ C 0.55 Suitable for aluminum and brass, high cutting speed 30˚ L 3˚ D (1) 0.6 When needed for blind hole - lower feed (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 Carbide Grades Two types of standard coatings are available: IC07 grade is the basic substrate for the reaming • IC907 – a TiAlN PVD coating for steel (P) and inserts. It is a very versatile submicron grade. stainless steel (M) workpiece material groups IC07 features very high fracture toughness and • IC507 - a TiCN+TiN PVD coating for cast iron (K) wear resistance, which is required for efficient workpiece material group high speed reaming. An uncoated IC07 can be used for machining The following grades can be provided on request: nonferrous (N type material group) applications. • PCD grade for machining aluminum • PCBN grade for machining cast iron • IC30N (cermet) for machining steel 696 696 ISCAR ISCAR
