Value Collection -20911-10 Mechanics Drill Bit 15/64 in

Product Description

The VALUE COLLECTION -20911-10 is a mechanics-length twist drill bit designed for general-purpose hole drilling in metal and ferrous materials. Built from high-speed steel with an oxide finish, it measures 15/64 inch (0.2344 inch) in diameter and features a 135-degree split point that reduces walking on contact and requires no center punch on most surfaces. The straight-cylindrical shank seats securely in standard three-jaw drill chucks. At 3-3/8 inches overall length with a 2-1/16 inch flute length, this is a compact mechanics-length bit suited for work in tighter clearances than jobber-length equivalents.

This bit is appropriate for production drilling, maintenance, and repair work across metal fabrication, mechanical assembly, and general machine shop applications. It is rated for use in carbon steel, cast iron, high alloy steel, high tensile strength alloys, stainless steel, and general steel. The regular spiral flute and parallel web configuration make it a reliable choice for repetitive drilling tasks where consistent chip evacuation and hole quality matter. It is sold individually but carries a minimum order quantity of 10 units.

Key Features

• 135-degree split point reduces drill walk and allows entry without a center punch on most metals
• High-speed steel construction provides heat resistance during continuous metal drilling
• Oxide coating finish adds surface protection and reduces friction at the cutting edge
• Mechanics length (3-3/8 inches OAL) offers better rigidity and access in confined spaces compared to jobber-length bits
• Web-thinned parallel web reduces thrust required at the cutting tip
• Right-hand cut with regular spiral flutes for efficient chip removal

Compatibility

Designed for drilling carbon steel, cast iron, high alloy steel, high tensile strength alloys, stainless steel, and general steel workpieces using standard drill chucks that accept straight-cylindrical shanks.

Installation Notes

Install in a standard keyed or keyless three-jaw drill chuck and ensure the shank is fully seated before tightening. Secure the workpiece firmly before drilling and apply appropriate cutting fluid when working with stainless steel or high alloy materials to extend tool life and improve hole finish. Wear appropriate eye protection and follow shop safety practices when operating drilling equipment.
