Kennametal 8.6mm 135° Spiral Flute Solid Carbide Screw Machine Drill Bit TiCN
Solid carbide provides better rigidity than high speed steel. It is extremely heat resistant and used for high-speed applications on cast iron, nonferrous materials, plastics and other tough-to-machine materials. Multilayer Titanium carbonitride (TiCN) is harder and more wear resistant than Titanium nitride (TiN). It is used on a variety of materials including stainless steel, cast iron and aluminum alloy. Spiral flutes are constructed of a higher flute angle to remove chips easier. Specs
