Precision Twist Drill 5996822 Jobber Drill Bit 9/16 in

Product Description

The PRECISION TWIST DRILL 5996822 is a 9/16 inch diameter jobber length drill bit designed for general-purpose drilling in metal and hard materials. Built from high speed steel with a bright uncoated finish, this bit features a 135-degree split point that reduces walking and starts on contact without a center punch. The parabolic flute profile improves chip evacuation in deeper holes. The overall length is 6.625 inches with a 4.8125 inch flute length, giving it a 9xD flute-to-diameter ratio suited to production and maintenance drilling alike. Licensed tradespeople and machinists working in fabrication, mechanical, or HVAC equipment service will find this a dependable everyday tool.

This bit is engineered for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits standard drill chucks with a 9/16 inch straight cylindrical shank and requires no special tooling to mount. Typical applications include field drilling for equipment mounting, structural steel fabrication, pipe and conduit work, and general metal removal tasks in both shop and on-site environments. The ANSI-standard geometry ensures consistent performance across common drill press and handheld drill setups.

Key Features

• 135-degree split point reduces bit walking and improves hole entry accuracy
• Parabolic spiral flute design promotes efficient chip evacuation from deep holes
• High speed steel construction handles steel, stainless steel, cast iron, and superalloys
• Web-thinned and tapered web configuration reduces thrust force during drilling
• 9/16 inch straight cylindrical shank fits standard drill chucks without adapters
• ANSI-compliant geometry for consistent fitment and dimensional accuracy

Compatibility

Designed as a general-purpose jobber length drill bit compatible with standard 3-jaw drill chucks and drill press spindles accepting a 9/16 inch straight cylindrical shank. Suitable for use across primary workpiece material codes P, M, K, N, and S as defined by ISO material classification.

Installation Notes

Installation and use should follow standard machine shop safety practices. Secure the shank firmly in a properly sized chuck before operation and verify chuck key is removed before powering the drill. Use appropriate cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to prevent work hardening and extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
