Iscar MM HT.625N31R187-2T10 IC908 Carbide Multi-Master Milling Head (2 Pcs)

This is a factory-new, 2-piece package of Iscar Multi-Master indexable solid carbide milling heads, part number MM HT.625N31R187-2T10 in grade IC908, Iscar item code 05604622. The Multi-Master system uses a proprietary threaded connection (the "MM" interface) to allow solid carbide cutting heads to be swapped onto steel or carbide shanks without disturbing the toolholder setup; the "HT" prefix designates a high-feed/high-torsion head geometry designed for helical interpolation, ramping, and slot milling in hardened and difficult materials. Decoding the part number: cutting diameter is 0.625 in (15.875 mm); "N31" denotes the Multi-Master thread size M31 (compatible with MM shanks accepting a 31 mm thread); "R187" encodes a corner radius of 0.187 in (approx. 4.76 mm); "2T10" indicates 2 effective flutes with 10° helix; grade IC908 is an ultra-fine-grain CVD-TiAlN-based PVD-coated carbide optimized for hardened steels and stainless/heat-resistant alloys, with ISO application ranges P15–P30, M20–M30, and K20–K30 as confirmed on the package label. The heads are manufactured in Israel and are packaged in Iscar's standard protective foam-insert plastic case.
