Solid Carbide Screw-Machine Length Drill Bits
Available5 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 EgiAs-Coated Spiral-Flute Solid Carbide Screw-Machine Length Drill Bits
The EgiAs coating on these drill bits resists oxidation at high temperatures and provides excellent hardness and heat resistance. The coating protects the bits from wear in high-speed drilling applications with steel, cast iron, and hardened steel with a Rockwell hardness of 35 to 50 HRC. 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.

AlTiN-Coated Spiral-Flute Solid Carbide Screw-Machine Length Drill Bits
The AlTiN coating on these drill bits protects them from wear when drilling hard and abrasive materials and is more resistant to high heat than a TiAlN coating. These drill bits do not have coolant holes, so a separate hose is required to bring coolant to the bits' tip if it is needed. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece.

Letter-Size Bright Finish Spiral-Flute Solid Carbide Screw-Machine Length Drill Bits
These drill bits come in standard letter sizes. The letter size for each bit indicates its compatibility with other tools that have the same letter size. Spiral-flute drill bits evacuate chips as the bits drill into a workpiece. The bright finish on these drill bits is not affected when the bits' cutting edges are resharpened.
