Precision Twist Drill 5998072 Wire Gauge 62 Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5998072 is a jobber-length drill bit in wire gauge size 62, with a decimal diameter of 0.0380 inches. Ground from high-speed steel with a bright uncoated finish, it features a standard 118-degree split-point angle and a two-flute regular spiral configuration for efficient chip evacuation. Overall length is 1.5 inches, with a 5/8-inch flute length and a 7/8-inch straight-cylindrical shank. This is a general-purpose bit suited for production and maintenance drilling operations where consistent hole quality in a range of materials is required. Licensed machinists, millwrights, and maintenance technicians are the primary users.

This bit is rated for drilling steel, cast iron, non-ferrous metals, superalloys, and titanium under the ISO material codes P, K, N, and S. It is well suited for precision drilling in tight-tolerance applications where a small-diameter wire gauge bit is needed. The jobber-length format and straight-cylindrical shank allow use in standard drill chucks on benchtop drill presses, CNC machines, and hand-held power drills. The 16xD flute-to-diameter ratio supports controlled depth drilling without packing chips in deep bores. Series designation is R10H-R18H per the manufacturer.

Key Features

• Wire gauge size 62, decimal diameter 0.0380 inches for precise small-hole applications
• 118-degree standard point angle with web-thinned, tapered web for reduced thrust on entry
• High-speed steel construction with bright uncoated finish
• Two-flute regular spiral design promotes clean chip evacuation
• Straight-cylindrical shank fits standard drill chucks without special tooling
• Conforms to ANSI standards for jobber-length drill geometry

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck that accepts a 0.0380-inch straight-cylindrical shank, including benchtop drill presses, manual mills, and CNC drilling stations.

Installation Notes

Installation is performed by machinists, toolroom technicians, or maintenance mechanics. Secure the shank fully in the chuck and verify concentricity before drilling to prevent bit deflection at this small diameter. Use appropriate cutting fluid or lubricant when drilling steel or titanium to extend tool life and improve hole finish. Replace the bit at first signs of dulling, as small-diameter HSS bits are prone to breakage if run worn.
