Precision Twist Drill 5997032 Drill Bit Wire 39 Hss

Product Description

The PRECISION TWIST DRILL 5997032 is a jobber-length drill bit designed for general-purpose drilling in metal and hard materials. Made from high speed steel with a bright uncoated finish, this bit features a 135-degree split point angle and a parabolic spiral flute for efficient chip evacuation. The straight cylindrical shank measures 0.0995 inches in diameter, matching the wire size 39 designation. A web-thinned, tapered web design reduces thrust at entry and improves centering on hard surfaces. This bit is installed by machinists, maintenance technicians, and trade professionals working with steel, stainless steel, cast iron, non-ferrous metal, superalloys, and titanium.

The 5997032 is suited for drilling operations in steel fabrication, HVAC bracket work, plumbing rough-in, electrical panel work, and general metal fabrication. With an overall length of 2.375 inches and a flute length of 1.375 inches, it fits standard drill chucks and drill presses used in light-duty to medium-duty production environments. Its ANSI-compliant construction makes it a reliable choice for shops and field technicians requiring consistent hole quality in wire-gauge applications.

Installation Notes

Install in a standard keyed or keyless chuck, ensuring the shank is fully seated before tightening. Always power down and de-energize or unplug the drill or drill press before changing bits. Use appropriate cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to extend bit life. Wear appropriate eye and hand protection per shop safety requirements.
