Cermet

The IGETALLOY micro-fine grained carbide series provides micro-fine grain structure at a world-class level to deliver superior performance in small drills and other tools. IGETALLOY micro-fine grained cemented carbides feature a WC structure between 0.2 and 1μm and are extremely strong and hard. They also provide excellent sharpness and superb surface quality on machined surfaces. These features provide excellent performance in a variety of applications from ø0.1mm PCB drills and endmill materials to thin-bladed slitters and precision moulds.
