Precision Twist Drill 5999701 Taper Length Drill Bit

Product Description

The PRECISION TWIST DRILL 5999701 is a taper length high speed steel drill bit designed for general purpose drilling across a wide range of materials. With a 0.1800 inch diameter (Wire Size 15), a 118-degree standard point angle, and a web-thinned tapered web configuration, this bit is built for consistent entry and reduced thrust in production and maintenance drilling. The bright/uncoated finish keeps the tool ready to use straight from the package. A right-hand spiral flute evacuates chips efficiently during through-hole and deep drilling operations. Licensed HVAC, plumbing, and electrical trades rely on drill bits like this for panel knockouts, bracket fabrication, and general metalwork.

This Series R52 taper length bit suits applications where extra flute length is needed beyond a standard jobber drill. The 3.375 inch flute length and 5.75 inch overall length give technicians reach into deeper setups without requiring an extended-length bit. The straight shank seats in standard three-jaw chucks. Material compatibility includes 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.

Installation Notes

Install in a properly sized chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Apply appropriate cutting fluid when drilling hardened steel or stainless steel to extend tool life and manage heat. Follow standard shop safety practices including eye protection and secure guarding of rotating equipment.
