HM90 APKT1003PDR IC908 Iscar 90° Shoulder Milling Insert For Steel & Stainless Steel

HM90 APKT1003PDR IC908 is a high-performance indexable milling insert designed for efficient 90-degree shoulder milling and face milling applications. As part of the Coromant HM90 milling system, this insert features the standard APKT1003PDR geometry combined with the advanced IC908 PVD-coated carbide grade, delivering excellent wear resistance, cutting stability, and consistent tool life in medium to high-speed milling operations.

This insert is ideal for shoulder milling, side milling, face milling, and cavity roughing to semi-finishing, offering low cutting forces, high metal removal rates, and reliable surface quality. It is widely used in industries such as general machining, automotive manufacturing, mold & die, and mechanical engineering.
