Solid Carbide Screw-Machine Length Drill Bits

Available3 products
Carbide screw-machine length drill bits provide excellent hardness, wear resistance, and heat resistance. They are harder than high-speed steel, cobalt, and powdered-metal drill bits and require a rigid setup such as a drill press. Screw-machine length drill bits are shorter than jobber length and maintenance length drill bits of the same size. Also called stub length drill bits, they provide more strength and rigidity and can drill straighter holes than longer drill bits. Their short length also allows them to access tight spaces where longer drill bits cannot fit.

Coolant-Through WXS-Coated Slow Spiral-Flute Solid Carbide Screw-Machine Length Drill Bits

Coolant-Through WXS-Coated Slow Spiral-Flute Solid Carbide Screw-Machine Length Drill Bits
The WXS coating on these drill bits protects them from wear and provides maximum heat resistance when drilling nickel-based alloys and hardened steels with a Rockwell hardness of more than 50 HRC. It is harder and has a higher oxidation temperature than a TiAlN coating. These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.
