Seco - 12.4mm 140° Spiral Flute Solid Carbide Screw Machine Drill Bit - TiAlN Finish, Right Hand Cut, 60mm Flute Length, 107mm OAL, Conical Point, Straight Shank, Through Coolant

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 Aluminum Nitride (TiAlN) has a higher hardness and oxidation temperature versus TiN and TiCN. As a result, it is particularly advantageous for higher speed operations in a variety of steel machining applications.

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.
