Solid Carbide Screw-Machine Length Drill Bits
Available11 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.
Flute Length
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.

Coolant-Through WXL-Coated Spiral-Flute Solid Carbide Screw-Machine Length Drill Bits
The WXL coating on these drill bits protects them from wear and is designed for drilling nonferrous metals and steels with a Rockwell hardness of up to 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.

Metric Bright Finish Spiral-Flute Solid Carbide Screw-Machine Length Drill Bits
These drill bits come in standard sizes expressed in millimeters. 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.

TiN-Coated Spiral-Flute Solid Carbide Screw-Machine Length Drill Bits
The TiN coating on these drill bits protects them from wear and heat when drilling steel, stainless steel, and aluminum. The bits' spiral flutes evacuate chips as the bits drill into a workpiece.

Coolant-Through WD1-Coated Spiral-Flute Solid Carbide Screw-Machine Length Drill Bits
The WD1 coating on these drill bits is harder than TiAlN and EgiAs coatings, has excellent heat resistance, and protects the tool from wear when drilling into steel, stainless steel, hardened steel, and cast iron. 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.
