Precision Twist Drill 5996947 3/8 Inch Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5996947 is a jobber-length drill bit designed for general-purpose drilling in a wide range of metallic and hard materials. Built from high-speed steel with a bright uncoated finish, it features a 135-degree split-point angle that reduces walking and requires no center punch on most surfaces. The parabolic spiral flute design promotes efficient chip evacuation, and the web-thinned tip reduces thrust during entry. At 5 inches overall length with a 3-5/8-inch flute length, this bit fits standard drill chucks and drill presses used daily in trade and fabrication work.

This drill bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It is appropriate for both shop and field use where a reliable general-purpose bit is needed. The straight cylindrical shank accepts standard three-jaw chucks without adapters. Machinists, maintenance technicians, pipefitters, and electricians commonly reach for this size and style when drilling through structural steel, pipe, conduit straps, and plate stock.

Key Features

Installation Notes

Install in a properly rated drill chuck and tighten securely before use. Power down and de-energize all equipment before changing bits. Use appropriate cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to extend bit life and maintain dimensional accuracy. Inspect the cutting edge before each use and replace bits showing chipping, wear, or burn marks.
