Value Collection -20903-10 Mechanics Drill Bit 7/64 in

Product Description

The VALUE COLLECTION -20903-10 is a mechanics-length drill bit designed for general-purpose metal drilling in professional and trade shop environments. It measures 7/64 inch (0.1094 inch decimal) in diameter with a 2-3/8 inch overall length and a 1-5/16 inch flute length. The 135-degree split point geometry reduces walking on entry and requires no center punch on most workpieces. Constructed from high-speed steel with an oxide finish, this bit is built to handle repeated use in production or field drilling tasks. The straight-cylindrical shank seats securely in standard three-jaw chucks across corded drills and drill presses.

This mechanics drill bit is suited for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel stock. The shorter mechanics length provides added rigidity compared to jobber-length bits, making it well suited for close-quarters drilling and applications where bit deflection is a concern. Right-hand cut spiral flutes clear chips efficiently during through-hole and blind-hole operations. It is a practical choice for machinists, maintenance mechanics, and metal fabricators working on ferrous materials in both shop and field settings.

Key Features

• 135-degree split point reduces entry walking and eliminates the need for center-punching on most metal surfaces
• High-speed steel construction provides heat resistance and edge retention during metal drilling
• Oxide finish offers basic corrosion resistance and reduces friction during cutting
• Mechanics length (2-3/8 inches OAL) delivers added rigidity over standard jobber bits
• Web-thinned parallel web configuration reduces cutting thrust and improves chip evacuation
• Straight-cylindrical shank fits standard three-jaw chucks without modification

Compatibility

Designed for use with carbon steel, cast iron, high alloy steel, high tensile strength alloy, stainless steel, and general steel workpieces. Fits any standard three-jaw drill chuck accepting a straight-cylindrical shank at 7/64 inch diameter.

Installation Notes

Install and remove only with the drill or drill press fully powered off and unplugged, or the spindle locked. Secure the workpiece with a vise or clamp before drilling to prevent rotation. Apply cutting fluid when drilling stainless steel or high alloy steel to extend bit life and reduce heat buildup. Inspect the cutting edges for wear or chipping before each use and replace the bit if the split point is damaged.
