Precision Twist Drill 5997994 Wire 44 Jobber Drill Bit Hss

Product Description

The PRECISION TWIST DRILL 5997994 is a jobber-length drill bit in wire gauge size 44, equivalent to 0.086 inches in decimal diameter. Ground from high speed steel with a bright uncoated finish, it features a standard 118-degree split-point angle and a regular spiral flute with web thinning for improved chip evacuation and reduced thrust. The straight cylindrical shank seats in standard drill chucks without modification. This is a general-purpose bit suited for production and maintenance drilling in metal fabrication, mechanical, and industrial service environments. It conforms to ANSI standards and carries a 13xD flute-to-diameter ratio for consistent performance in short-hole applications.

This bit is designed for drilling steel, cast iron, non-ferrous metals, superalloys, and titanium in typical shop and field conditions. It fits the R10H-R18H series classification and is appropriate for use in benchtop drill presses, hand drills, and CNC drilling operations where a wire-size 44 diameter is required. Two flutes and a tapered web configuration support effective chip clearing in through-hole and blind-hole applications at standard cutting speeds for HSS tooling.

Compatibility

Designed as a general-purpose OEM-style jobber drill bit in wire size 44 for use with standard drill chucks in benchtop, handheld, and machine tool drilling applications on steel, cast iron, non-ferrous metals, superalloys, and titanium workpieces.

Installation Notes

Installation and use should be performed by machinists, maintenance technicians, or qualified tradespeople familiar with rotating cutting tools. Power down and disconnect all energy sources before changing bits in any powered drill or machining center. Secure the shank fully in the chuck and verify concentricity before applying cutting pressure. Do not exceed the recommended cutting speed for HSS tooling on the intended workpiece material.
