Precision Twist Drill 5999697 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5999697 is a taper length high speed steel drill bit designed for general-purpose drilling across a wide range of materials. Sized at 0.1820 inches in diameter (Wire Size #14), it features a 118-degree standard point angle and a spiral flute with a 6xD flute-to-diameter ratio, giving it extended reach beyond a jobber-length bit while maintaining accurate starts and clean chip evacuation. The bright, uncoated finish suits dry or lubricated cutting. Right-hand cut with a straight shank, this bit is a go-to for maintenance technicians, electricians, machinists, and plumbers who need reliable performance in tight or deep-hole applications.

This drill bit is suited for production and maintenance drilling in residential, commercial, and light industrial environments. The taper length configuration provides additional flute length compared to jobber bits, making it appropriate for deeper holes or setups where a standard-length bit falls short. It performs across a broad material range including carbon steel, stainless steel, aluminum, brass, bronze, copper, cast iron, malleable iron, nickel alloys, magnesium alloys, hardened steel, high strength bronze, cermet, graphite, and reinforced plastic materials. Series R52 designates its place within the Precision Twist Drill general-purpose catalog line.

Installation Notes

Install in a properly sized drill chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Apply appropriate cutting fluid when drilling ferrous metals or stainless steel to extend bit life and improve hole finish. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.
