Dapra’s DMK25 insert substrate features a micro-grain structure with medium cobalt content, providing very good edge strength and wear resistance while maintaining outstanding toughness, the company says. This grade was formulated for applications involving tool steels, austenitic stainless steels and most high-temperature alloys. It is available in the manufacturer’s proprietary D (dished) and N (neutral) Rhino-Carb CNC-pressed insert geometries. It is available in the following coatings: DMK25-GLH (premium AlTiN), DMK257 (basic AlTiN), DMK25-HP (premium AlCrN) and DMK253 (TiCN).
