Precision Twist Drill 5996962 Jobber Drill Bit Wire 13

Product Description

The PRECISION TWIST DRILL 5996962 is a jobber-length drill bit in wire gauge size 13, measuring 0.1850 inches in diameter. Built from high-speed steel with a bright uncoated finish, it features a 135-degree split point and a parabolic spiral flute design that promotes chip evacuation and reduces thrust during drilling. The straight-cylindrical shank seats securely in standard drill chucks. At 3.5 inches overall length with a 2.3125-inch flute length, this bit handles general-purpose drilling in a wide range of metallic materials. It is sold individually and suited for use by machinists, maintenance technicians, and metalworking tradespeople.

This drill bit is designed for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It performs well in production and maintenance applications where consistent hole size and clean entry are required at wire gauge tolerances. The QC21P series designation indicates a heavy-duty, general-purpose tool built to ANSI standards. Typical applications include precision hole placement in fabrication, repair work, and light manufacturing environments where a 0.1850-inch diameter hole is specified.

Key Features

• Wire gauge size 13 with 0.1850-inch decimal diameter for precise hole sizing
• 135-degree split point reduces walking and lowers drilling thrust
• High-speed steel construction with web-thinned, tapered web for improved chip clearance
• Parabolic spiral flute geometry supports efficient chip removal in deep-hole drilling up to 2.3125 inches
• Straight-cylindrical shank compatible with standard 3-jaw and keyless drill chucks
• Bright uncoated finish suitable for use with or without cutting fluid

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard drill presses, hand drills, and CNC drilling applications requiring a wire gauge size 13 or 0.1850-inch diameter bit built to ANSI specifications.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press, hand drill, or CNC machine with an appropriately sized chuck. Secure the shank fully in the chuck before operation and verify chuck key removal before powering the spindle. Apply cutting fluid when drilling stainless steel, superalloys, or titanium to extend tool life and improve hole quality. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.
