Precision Twist Drill 5996988 Jobber Drill Bit 24 Hss

Product Description

The PRECISION TWIST DRILL 5996988 is a jobber-length drill bit designed for general-purpose drilling in metal and hard materials. It is a wire gauge size 24 bit with a decimal diameter of 0.152 inches, manufactured from high speed steel with a bright uncoated finish. The 135-degree split-point tip reduces walking on entry and requires less feed pressure than a conventional 118-degree point. A parabolic spiral flute with web thinning improves chip evacuation and reduces heat buildup at depth. Licensed trades and machinists use this bit for production and maintenance drilling in ferrous and non-ferrous workpieces.

This bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It fits standard drilling applications on drill presses, CNC machines, and handheld power drills. The straight cylindrical shank seats in any standard three-jaw chuck. With a flute-to-diameter ratio of 13xD and a maximum drilling depth of 2 inches, it handles through-holes and blind holes in production environments. It is part of the QC21P series, which is rated for heavy-duty general-purpose work to ANSI standards.

Installation Notes

Installation and use should be performed by machinists, tool and die workers, or qualified tradespeople familiar with metal drilling operations. Secure the shank fully in the chuck and verify runout before drilling. Always wear appropriate eye protection and secure the workpiece before drilling. Do not exceed the recommended maximum drilling depth of 2 inches for this bit length.
