Sandvik Coromant - 7/32" 130° Spiral Flute Solid Carbide Screw Machine Drill Bit

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.

Uncoated tools do not feature supportive treatments on the cutting edge. They are are used at reduced speeds for general applications on non-ferrous metals.

Spiral flutes are constructed of a higher flute angle to remove chips easier.

Spiral flute reamers are used in blind and through-hole operations. They are used to bridge interrupted cuts.
