Precision Twist Drill 5998409 17/32 in Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5998409 is a jobber-length drill bit designed for general-purpose drilling in metal and hard materials. It features a 17/32 inch (0.5313 inch) diameter with a straight-cylindrical shank of the same diameter, a 118-degree standard point angle, and a bright uncoated finish. Made from high speed steel, it delivers reliable performance across a range of ferrous and non-ferrous materials. The two-flute, right-hand spiral configuration promotes efficient chip evacuation during through-hole and blind-hole drilling. Licensed tradespeople and industrial maintenance technicians rely on this bit for day-to-day metal fabrication and repair work.

This bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium in both shop and field environments. With an overall length of 6.625 inches and a flute length of 4.8125 inches, it fits standard drill chucks and magnetic drill presses used in HVAC, plumbing, electrical, and general mechanical work. The regular spiral and tapered web configuration with web thinning reduce thrust requirements when entering harder materials. It carries ANSI specification designation and belongs to the R10P-R15P-R18P series.

Installation Notes

Install in a properly sized drill chuck and tighten securely before use. Power down or de-energize any drill press or power tool before changing bits. Apply cutting fluid when drilling ferrous metals or hard materials to manage heat and extend bit life. Follow applicable shop safety standards and wear appropriate PPE including eye protection during all drilling operations.
