Precision Twist Drill 5996585 Jobber Drill Bit 11mm Hss

Product Description

The PRECISION TWIST DRILL 5996585 is an 11 mm high speed steel jobber length drill bit designed for general-purpose drilling across a wide range of materials. Built to DIN 338 standards, it features a 135-degree split point for fast penetration and reduced walking on hard surfaces. The bright uncoated HSS construction delivers reliable performance in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. A parabolic spiral flute with web thinning promotes efficient chip evacuation, reducing heat buildup during drilling. This bit is a fit for production shops, maintenance crews, and trade professionals who need a dependable metric drill bit in the 0.4331-inch decimal equivalent range.

The 5996585 is suited for general drilling applications in both shop and field environments. Its straight cylindrical shank seats securely in standard drill chucks, making it compatible with bench drills, magnetic drills, and handheld drill drivers. The right-hand cut and regular spiral geometry are appropriate for drilling through steel plate, structural members, piping, and fabricated components. The QC21PM series is rated as heavy duty and follows DIN 338 geometry, making it a practical choice for HVAC fabricators, pipefitters, ironworkers, and maintenance technicians who regularly work with ferrous and non-ferrous metals.

Installation Notes

Install and remove drill bits only with the drill fully powered down and the chuck key removed from the chuck. Secure the shank fully into the chuck jaws and tighten evenly before drilling. Use appropriate cutting fluid or coolant for steel and stainless steel applications to extend bit life and reduce heat buildup. Follow applicable shop safety practices and any site-specific PPE requirements when operating drilling equipment.
