Precision Twist Drill 5997715 Wire 45 Drill Bit Hss

Product Description

The PRECISION TWIST DRILL 5997715 is a jobber length drill bit sized to wire gauge 45 (0.0820 inches decimal), manufactured from high speed steel with a steam oxide coating. It features a 135-degree split-point tip geometry that reduces walking on contact and lowers thrust requirements compared to a standard 118-degree point. The two-flute, right-hand spiral design provides efficient chip evacuation during through-hole and blind-hole drilling. Overall length is 2.125 inches with a flute length of 1.125 inches, making it well-suited for confined drilling operations in light-gauge work. Licensed HVAC technicians, machinists, pipefitters, and electricians use bits in this size range for pilot holes, sheet metal, and precision through-holes in ferrous and non-ferrous materials.

This bit is rated for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its steam oxide finish improves lubricity and provides moderate corrosion resistance during storage and use. The straight cylindrical shank fits standard drill chucks across portable drills, drill presses, and CNC drilling equipment. The web-thinned, tapered web configuration reduces cutting resistance in harder workpiece materials. This is a general-purpose, heavy-duty rated bit appropriate for job-site and shop use where consistent hole quality in small-diameter applications is required.

Key Features

• Wire gauge 45 size (0.0820 inches) with matching straight cylindrical shank diameter of 0.0820 inches
• 135-degree split-point tip reduces bit walking and lowers entry thrust on hard materials
• Steam oxide coating improves surface lubricity and resists corrosion during storage
• Web-thinned tapered web reduces cutting resistance across a range of workpiece materials
• Two-flute regular spiral design evacuates chips efficiently in both ferrous and non-ferrous materials
• Meets ANSI standards and NAS 907 specification designation

Compatibility

Designed for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Fits any standard drill chuck accepting a 0.0820-inch straight cylindrical shank. Part of the Series R10B-R15B-R18B family.

Installation Notes

Secure the shank fully in the drill chuck before operation and verify chuck key is removed. Use cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to extend bit life and maintain hole quality. Do not force the bit at excessive feed rates in hard materials, as small-diameter bits are susceptible to breakage under lateral load. Drilling depth is limited to the maximum flute length of 1.125 inches for effective chip clearance.
