Value Collection 01370089 Cobalt Screw Machine Drill Bit

Product Description

The VALUE COLLECTION 01370089 is a cobalt screw machine length drill bit designed for high-speed drilling in tough materials including stainless steel, hardened alloys, and abrasion-resistant metals. The 1/8 inch diameter bit features a 135-degree split point that self-centers on contact, reducing the need for a center punch and minimizing walking on hard surfaces. At 1-7/8 inches overall length, the screw machine format provides added rigidity over jobber-length bits, making it well suited for precision work in confined areas or on drill presses. This is a heavy-duty grade bit intended for professional shop and field use by machinists, pipefitters, electricians, and HVAC technicians.

This bit is built for applications where standard high-speed steel bits fail prematurely. Screw machine length bits are commonly used in production drilling, sheet metal work, and mechanical assembly where short, rigid tooling reduces deflection and improves hole accuracy. The right-hand cutting direction is standard for conventional drill press and hand drill operation. The regular spiral flute design efficiently clears chips from the hole during drilling, and the straight shank fits standard three-jaw chucks without adapters.

Key Features

• Cobalt construction for extended tool life in hard and abrasive materials
• 135-degree split point self-centers and reduces thrust required to start the hole
• Screw machine length provides greater rigidity than jobber-length bits
• Right-hand cut, regular spiral flutes for efficient chip evacuation
• Straight shank compatible with standard drill chucks
• Heavy-duty grade rated for demanding production and maintenance environments

Compatibility

Designed as a standard screw machine length drill bit for use in any three-jaw chuck or drill press accepting a straight shank at 1/8 inch diameter.

Installation Notes

Installed and operated by machinists, maintenance technicians, and trade professionals using hand drills or drill presses. Secure the workpiece before drilling and verify chuck tightness before operation. Use appropriate cutting fluid when drilling hard metals to extend bit life and reduce heat buildup. Inspect the cutting edges for wear or chipping before each use and replace worn bits promptly to maintain hole quality.
