Value Collection 20904 Mechanics Drill Bit 1/8 in Hss

Product Description

The VALUE COLLECTION 20904 is a mechanics-length, high-speed steel twist drill bit designed for general-purpose hole drilling in metal and ferrous materials. It measures 1/8 inch (0.1250 inch decimal) in diameter with a 2-1/2 inch overall length and a 1-7/16 inch flute length. The 135-degree split point reduces walking on contact and lowers the thrust required to start a hole, making it well suited for hand-held and bench-drill work in production and service environments. The straight-cylindrical shank seats in standard three-jaw chucks without modification. An oxide finish provides a degree of surface hardness and lubricity for extended service life in repetitive drilling tasks.

This bit is intended for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloys, stainless steel, and general steel stock. The mechanics-length body — shorter than a jobber-length bit — gives added rigidity and reduced deflection when clearance is limited, such as in tight engine bays, panel work, or mechanical assemblies. It is a standard tool for HVAC technicians, pipefitters, electricians, and general mechanics who need reliable metal drilling performance in confined spaces.

Key Features

• 135-degree split point reduces drill walking and lowers feed pressure on hard metals
• Web-thinned geometry improves chip evacuation and reduces heat buildup
• High-speed steel construction maintains cutting edge integrity across carbon steel, cast iron, and stainless steel
• Mechanics length (2-1/2 inch OAL) provides added rigidity and suits confined-space applications
• Oxide coating adds surface lubricity and corrosion resistance for extended service life
• Straight-cylindrical shank fits standard three-jaw drill chucks without adapters

Compatibility

Designed as a general-purpose replacement or stocking drill bit for use with any standard three-jaw chuck accepting a straight-cylindrical shank. Rated for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloys, stainless steel, and general steel workpieces.

Installation Notes

Install this bit into a properly sized three-jaw chuck and tighten with a chuck key before operating. Always power down or de-energize any drill press before changing bits. Use appropriate cutting fluid or lubricant when drilling stainless steel or high-alloy materials to reduce heat and extend bit life. Eye protection is required during all drilling operations.
