Precision Twist Drill 5998360 Jobber Drill Bit Wire 3

Product Description

The PRECISION TWIST DRILL 5998360 is a jobber-length drill bit in wire gauge size 3 (0.2130 inches), designed for general-purpose drilling in metal and hard materials. Built from high speed steel with a steam oxide coating, it resists corrosion and reduces friction during cutting. The standard 118-degree split point and web-thinned tip promote accurate starting and reduce feed pressure. With an overall length of 3.75 inches and a spiral flute length of 2.5 inches, this bit suits a wide range of bench drill press and hand drill applications. Licensed HVAC techs, plumbers, electricians, and general trade professionals keep jobber-length HSS bits like this one on hand for everyday metal drilling tasks.

This bit is suited for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The straight cylindrical shank fits standard drill chucks without adapters. At 3.75 inches overall, it handles typical through-hole and blind-hole work in sheet metal, plate stock, brackets, and enclosures common to residential and light commercial trade work. It is a single-piece, individually packaged unit appropriate for toolbox stock or job-site use.

Installation Notes

Install and remove drill bits only with the drill unplugged or the power source locked out and tagged out per site safety procedures. Secure the workpiece firmly before drilling to prevent movement. Use cutting fluid or coolant when drilling stainless steel, superalloys, or titanium to manage heat buildup and extend bit life. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.
