Solid Carbide Screw-Machine Length Drill Bits
Available27 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.

TiAlN-Coated Helical-Flute Solid Carbide Screw-Machine Length Drill Bits
Helical-flute drill bits create smaller chips and evacuate them more quickly than standard spiral-flute drill bits. These drill bits have a TiAlN coating that withstands high temperatures and protects the bits from wear during high-speed, dry machining applications with difficult-to-machine ferrous metals. The bits do not have coolant holes, so a separate hose is required to bring coolant to the bits' tip if it is needed.

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 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.

Coolant-Through TiAlN-Coated Helical-Flute Solid Carbide Screw-Machine Length Drill Bits
Helical-flute drill bits create smaller chips and evacuate them more quickly than standard spiral-flute drill bits. These drill bits have a TiAlN coating that withstands high temperatures and protects the bits from wear during high-speed, dry machining applications with difficult-to-machine ferrous metals. Coolant-through drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling.

Coolant-Through AlCrN-Coated Helical-Flute Solid Carbide Screw-Machine Length Drill Bits
Helical-flute drill bits create smaller chips and evacuate them more quickly than standard spiral-flute drill bits. The AlCrN coating on these drill bits protects them from wear during dry, high-speed machining applications. It is harder, resists cracking and oxidization better, and performs better in high-feed applications than a TiAlN coating. It also resists high heat better than an AlTiN coating. These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling.
