Precision Twist Drill 5998703 Jobber Drill Bit 19/32 in

Product Description

The PRECISION TWIST DRILL 5998703 is a jobber-length drill bit designed for general-purpose drilling in a wide range of ferrous and non-ferrous materials. It measures 19/32 inches (0.5938 inches) in diameter with an overall length of 7.125 inches and a flute length of 5.1875 inches. The bit is manufactured from high speed steel with a steam oxide coating that reduces friction and helps resist corrosion during use. The 118-degree standard point angle and web-thinned, tapered web configuration improve penetration and reduce the thrust required to start a hole. This is a straight-cylindrical shank bit suited for standard drill chucks used by machinists, maintenance technicians, and trade professionals.

This drill bit is rated for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium, covering ISO material codes P, M, K, N, and S. It fits production drilling, maintenance and repair operations, and general fabrication applications where a reliable, right-hand spiral-flute jobber bit is required. The Series R10 designation places it in PRECISION TWIST DRILL's standard general-purpose jobber line, built to ANSI specifications. Maximum drilling depth matches the flute length at 5.1875 inches.

Installation Notes

Install in a drill press, hand drill, or CNC spindle with a chuck rated for the 19/32 inch shank diameter. Secure the shank fully in the chuck before beginning operation and confirm the bit runs true with no visible runout. Apply appropriate cutting fluid when drilling stainless steel, superalloys, or titanium to extend tool life and improve hole finish. Follow applicable shop safety standards and wear appropriate eye protection during all drilling operations.
