Precision Twist Drill 5999703 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5999703 is a taper length high speed steel drill bit designed for general-purpose drilling across a wide range of materials. It features a 0.1770-inch diameter with a 118-degree standard point angle and a bright, uncoated finish. The straight shank and right-hand spiral flute design deliver clean, consistent cuts in production and maintenance environments. The tapered web configuration with web thinning reduces thrust and improves chip evacuation. At 5.75 inches overall length with a 3.375-inch flute length, this bit provides extended reach compared to standard jobber-length bits while maintaining rigidity.

This drill bit is suited for metalworking and fabrication applications where extended flute length is needed to reach deeper holes or work through thicker stock. It performs in residential, commercial, and light industrial settings. Compatible material applications include alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, high strength bronze, magnesium, magnesium alloy, malleable iron, nickel, nickel alloy, reinforced plastic materials, and stainless steel. The Series R52 designation identifies it within the PRECISION TWIST DRILL taper length line, built to ANSI standards.

Installation Notes

Install in a keyed or keyless drill chuck rated for the shank diameter before applying power. Secure the workpiece before drilling to prevent movement. Use appropriate cutting fluid when drilling hardened steel or stainless steel to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and regrind or replace when dulling is evident.
