Precision Twist Drill 5998248 Jobber Drill Bit 13/32 in

Product Description

The PRECISION TWIST DRILL 5998248 is a jobber-length drill bit designed for general-purpose drilling in metal fabrication, maintenance, and industrial applications. It measures 13/32 inches (0.4063 inches) in diameter with a 5.25-inch overall length. The bit is manufactured from high-speed steel with a bright uncoated finish and features a standard 118-degree point angle. A right-hand spiral flute with web-thinned, tapered web geometry promotes efficient chip evacuation and reduces walking at entry. Licensed trade professionals and industrial machinists are the primary users of this bit in production and field service settings.

This drill bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium in both shop and field environments. The straight cylindrical shank fits standard three-jaw drill chucks across a wide range of hand drills, drill presses, and magnetic base drills. With a flute length of 3.875 inches and a maximum drilling depth of 3.875 inches, it handles typical through-hole and deep-hole operations in structural and fabricated components. The Series R10P designation places it within PRECISION TWIST DRILL general-purpose jobber geometry conforming to ANSI standards.
