Walter-Titex - 6.8mm 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.

Tinal is extremely wear resistant coating when used at high temperatures and speeds in a wide range of high strength applications. It is commonly used on steel, cast iron and non-ferrous metal. Tinal is a proprietary coating exclusive to Walter Titex.

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.
