Somma DAV-CIN-8-17 Indexable Cut-Off Inserts MIC Tin Grade

Somma DAV-CIN-8-17 Indexable Cut-Off Inserts MIC Tin Grade are 3/4-inch square, 8° cut-off micro-carbide inserts coated with titanium nitride (TiN) to deliver wear resistance and low friction in part-off and grooving operations. Part of the DAV-CIN family, these inserts feature four cutting edges and index within.001 inches for repeatable seating, maximizing edge life between changes in Somma cut-off tool holders. The MIC designation indicates micro-carbide construction, offering a fine-grain, hard edge that sustains cutting performance under demanding conditions. The TiN coating enhances wear and corrosion resistance, helping to extend tool life during repeated part-off cycles when used with compatible 3/4" square DAV-CIN holders. A chip-breaker variant is available (DAV-CIN-8-CB) for improved chip control and reduced long, stringy chips in tighter operations. This 8° geometry is designed to produce clean part-off surfaces and consistent chip formation, aligning with Somma’s standard cut-off insert specifications and ensuring compatibility with standard 3/4" square pocket tools in the DAV-CIN lineup.
