Precision Twist Drill 5996262 Jobber Drill Bit 27/64

Product Description

The PRECISION TWIST DRILL 5996262 is a jobber-length drill bit designed for general-purpose drilling in metal and hard materials. Manufactured from M2 high speed steel with a purple/bronze coating, it measures 27/64 inch (0.4219 inches) in diameter and 5.375 inches in overall length. The 135-degree split-point tip reduces walking and breakthrough burrs compared to standard 118-degree points. Web thinning further reduces thrust and improves chip clearance. This bit is suited for use in production shops, maintenance facilities, and field service applications by machinists, pipefitters, and industrial tradespeople.

The 5996262 is built for drilling into steel, stainless steel, cast iron, superalloys, and titanium — material grades P, M, K, and S. The 9xD flute-to-diameter ratio provides adequate chip evacuation for through-hole drilling at typical jobber depths. The straight cylindrical shank fits standard three-jaw drill chucks across corded and cordless drill platforms. With a maximum drilling depth of 3.9375 inches, it covers the majority of jobber-length through-hole applications in structural, mechanical, and process piping work.

Compatibility

Designed for use in standard three-jaw drill chucks accepting a 27/64-inch (0.4219-inch) straight cylindrical shank. Suitable for drilling steel, stainless steel, cast iron, superalloys, and titanium in general-purpose applications.

Installation Notes

Secure the shank firmly in a properly sized drill chuck before operation and confirm there is no runout. Always power down or de-energize the drill press or hand drill before changing bits. Use appropriate cutting fluid or coolant when drilling stainless steel, cast iron, or titanium to manage heat buildup and extend tool life. Wear appropriate eye protection and follow applicable shop safety standards during all drilling operations.
