Precision Twist Drill 5998063 Jobber Drill Bit Wire 6

Product Description

The PRECISION TWIST DRILL 5998063 is a jobber-length drill bit sized to wire gauge 6, equivalent to 0.2040 inches in diameter. Built from high-speed steel with a bright uncoated finish, it is designed for general-purpose drilling in steel, cast iron, non-ferrous metals, and superalloys including titanium. The 118-degree standard point angle provides reliable self-centering on flat and curved surfaces. With an overall length of 3.75 inches and a 2.5-inch spiral flute, it offers a practical reach-to-diameter ratio suited for production and maintenance drilling tasks. Licensed HVAC techs, plumbers, electricians, and general tradespeople keep bits like this in rotation for sheet metal, conduit, and structural drilling work.

This bit fits standard drilling applications in both residential and light commercial settings. The straight cylindrical shank seats directly into three-jaw drill chucks on handheld drills, drill presses, and magnetic drills without requiring an adapter. It is well suited for drilling pilot holes, clearance holes, and through-holes in steel plate, angle iron, tubing, aluminum, and copper. The 2-flute spiral configuration clears chips efficiently during moderate-depth drilling passes.

Key Features

• Wire gauge 6 diameter: 0.2040 inches — precise sizing for standard clearance and tap-drill applications
• 118-degree standard point angle with web-thinned tip for reduced thrust and easier start
• High-speed steel construction handles steel, cast iron, non-ferrous metals, superalloys, and titanium
• Regular spiral, 2-flute design promotes efficient chip evacuation during drilling
• Straight cylindrical shank fits standard 3-jaw chuck without adapters
• ANSI-compliant jobber-length geometry — Series R10H-R18H

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard 3-jaw drill chuck accepting a 0.2040-inch straight cylindrical shank. Primary workpiece material codes P, K, N, and S indicate suitability for steel, cast iron, non-ferrous metals, and superalloys including titanium.

Installation Notes

Installation is performed by any trade professional or skilled technician using a corded or cordless drill or drill press. Secure the shank fully in the chuck and verify the bit runs true before drilling. Power down and de-energize any equipment being drilled into before starting work, in accordance with applicable OSHA lockout/tagout procedures. Use appropriate cutting fluid on hard metals to extend bit life and improve hole quality.
