Walter-Titex - 16mm 140° 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.

Aluminum chromium nitride (AlCrN) has higher-heat resistance than AlTiN. It is commonly used for machining aircraft and aerospace materials, nickel alloys, stainless steel, titanium, cast iron and carbon steel.

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.
