SGS - #21 145° Solid Carbide Jobber Drill
Item #: 33207820
Brand: SGS
Model #: 51569
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 with a higher flute angle to remove chips more easily.
