Precision Twist Drill 5997016 Wire 32 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5997016 is a high speed steel jobber-length drill bit sized to wire gauge 32 (0.1160 inches decimal). It features a 135-degree split point with web thinning, which reduces walking on entry and lowers thrust requirements compared to a standard 118-degree point. The bright uncoated finish suits general-purpose drilling in steel, aluminum, and other non-ferrous materials. With an overall length of 2.75 inches and a 1.625-inch flute length, this bit fits standard drill chucks on benchtop drill presses and handheld power tools. It is part of the QC21P series and conforms to ANSI standards. Machinists, maintenance technicians, and metalworking tradespeople are the primary users.

This drill bit is suited for production and maintenance drilling in ferrous and non-ferrous metals including steel and aluminum. The 14xD flute-to-diameter ratio and regular spiral flute geometry provide good chip evacuation in through-hole and blind-hole applications at wire-gauge diameters. Typical applications include pilot holes, clearance holes, and light sheet metal work where a small-diameter, general-purpose bit is required. The straight cylindrical shank accepts standard Jacobs-style chucks without any adapter.

Key Features

• Wire gauge size 32 (0.1160 inches) with matching straight shank diameter of 0.1160 inches
• 135-degree split point with web thinning reduces walking and improves centering on entry
• High speed steel construction for general-purpose drilling in steel, aluminum, and non-ferrous materials
• Bright uncoated finish suitable for use with cutting fluids or dry
• Regular spiral, 2-flute design promotes efficient chip removal
• ANSI-compliant QC21P series geometry for consistent dimensional accuracy

Compatibility

Designed as a general-purpose jobber drill bit compatible with any standard drill chuck accepting a 0.1160-inch straight cylindrical shank. Rated for use in steel, aluminum, and non-ferrous workpiece materials per ANSI standards.

Installation Notes

A licensed machinist or qualified maintenance technician should secure the shank fully in a properly sized drill chuck before use. Ensure the workpiece is clamped or fixtured to prevent rotation at small-diameter drill sizes. Apply an appropriate cutting fluid when drilling ferrous metals to extend tool life. Inspect the cutting edges for wear before each use, as small-diameter bits are susceptible to breakage if run at incorrect speeds or feeds.
