Precision Twist Drill 5996829 9/64 in Hss Jobber Drill

Product Description

The PRECISION TWIST DRILL 5996829 is a 9/64 inch high speed steel jobber-length drill bit designed for general-purpose drilling in metal, aluminum, and non-ferrous materials. It features a 135-degree split-point geometry with web thinning, which reduces walking on entry and lowers the thrust force needed to start a hole. The bright uncoated finish keeps the bit ready to use straight out of the package with no coating to chip or flake. With a 2-7/8 inch overall length and a regular spiral flute, this bit is a standard tool for machinists, HVAC technicians, electricians, and plumbers who need a reliable jobber drill for everyday hole-making tasks.

This drill bit is suited for drilling steel, aluminum, and other non-ferrous workpieces in both production and maintenance applications. The straight cylindrical shank accepts standard three-jaw drill chucks on benchtop drill presses, hand drills, and right-angle drills. The 1-3/4 inch flute length provides adequate chip clearance for through-holes in typical sheet metal, structural members, and piping brackets encountered in trade work. It conforms to ANSI standards and belongs to PRECISION TWIST DRILL Series QC21P.

Installation Notes

Install and remove drill bits only when the drill press or hand drill is fully powered off and the chuck has stopped rotating. Secure the shank firmly in the chuck using a chuck key before starting the tool. Use appropriate cutting fluid or lubrication when drilling steel to extend bit life and maintain hole quality. Wear eye protection and secure the workpiece before drilling.
