Precision Twist Drill 5997040 Wire 37 Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5997040 is a jobber-length twist drill bit sized to wire gauge 37 (0.1040 inches) with a 135-degree split-point tip and a high-speed steel construction. Finished with a bright uncoated surface, it measures 2.5 inches overall with a 1-7/16-inch flute length. The parabolic-style spiral flute and web-thinned tip reduce thrust and improve chip evacuation in a general-purpose drilling context. Manufactured to ANSI standards and designated as heavy-duty grade, this bit belongs to the QC21P series. Licensed HVAC technicians, pipefitters, electricians, and machinists use wire-gauge bits like this for precision pilot holes, sheet metal work, and conduit preparation.

This drill bit is rated for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The straight-cylindrical shank fits standard 3-jaw drill chucks without modification. It is well suited to light production and maintenance drilling where a small-diameter hole with consistent finish is required. The 14xD flute-to-diameter ratio supports moderate drilling depths up to 1-7/16 inches without coolant feed, keeping setup simple for field use.

Key Features

• Wire gauge 37 diameter: 0.1040 inches for precision small-bore drilling
• 135-degree point angle reduces walking and lowers thrust on entry
• Web-thinned, tapered-web construction improves chip flow and reduces heat buildup
• High-speed steel construction handles steel, stainless, cast iron, and non-ferrous metals
• Straight-cylindrical shank fits standard drill chucks without adapters
• Meets ANSI standards; QC21P series heavy-duty grade

Compatibility

Designed as a general-purpose replacement or stock bit for any drill press, hand drill, or CNC setup accepting a straight-cylindrical shank at 0.1040 inches diameter. No coolant-through requirement; compatible with standard dry or mist-assisted drilling operations.

Installation Notes

Install this bit into a properly sized 3-jaw chuck and tighten securely with a chuck key before operation. Ensure the workpiece is firmly clamped before drilling to prevent walking on entry. For stainless steel or titanium applications, use appropriate cutting fluid and moderate feed pressure to extend bit life. Inspect the cutting edges and point geometry before each use and replace the bit if chipping or excessive wear is observed.
