SGS - 4mm 145° Spiral Flute Solid Carbide Screw Machine Drill Bit
Item #: 58994039
Brand: SGS
Model #: 68550
Features and Benefits
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.
Titanium carbonitride (TiCN) is harder and more wear resistant than TiN. It is commonly used on stainless steels, cast iron and aluminum alloys.
Spiral flutes are constructed of a higher flute angle to remove chips easier.
