IC1008 K20-K40 Recommended for general use on a wide range of applications and materials as steels, alloy steels, austenitic stainless steel and TiN S15-S30 high temperature alloys at moderate cutting speeds. TiAlN H20-H30 Base P15-P30 A tough submicron grain size substrate with PVD coating. M20-M30 Recommended for general use on a wide range of applications IC1010 K20-K40 and materials such as steels, alloy steels, austenitic stainless steel and high temperature alloys at moderate cutting speeds and low TiN S15-S30 to medium feeds. The grade features improved toughness and AITiN H20-H30 wear resistance which extends tool life. Base P30-P45 M25-M40 A tough substrate with PVD coating, suitable for machining IC1028 steel and stainless steel at low to medium cutting speeds and moderate to high feeds. The grade is recommended for TiN interrupted cuts and machining under unstable conditions. AlTiCrN Base P30-P45 M25-M40 A tough substrate with PVD coating, suitable for machining steel and stainless steel at low to medium cutting speeds and IC1030 moderate to high feeds. Recommended for interrupted cuts and machining under unstable conditions. The grade features TiN improved toughness and wear resistance which extends tool life. AITiN Base P30-P45 M25-M45 A tough substrate with MTCVD coating and a special SUMOTEC IC5400 post coating treatment.
