Precision Twist Drill 5996926 Jobber Drill 7.50mm Hss

Product Description

The PRECISION TWIST DRILL 5996926 is a 7.50 mm high-speed steel jobber 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 angle for fast penetration and reduced walking on initial contact. The web-thinned, tapered-web construction lowers thrust requirements, making it well suited for production drilling environments. At 4.2969 inches overall length with a 2.7188-inch flute length, this bit fits standard drill chucks and is appropriate for use in hand drills, drill presses, and CNC machining centers. Machinists, fabricators, and maintenance technicians are the primary installers.

This jobber drill is rated for use in steel, aluminum, and non-ferrous metals, corresponding to material codes P, M, K, N, and S. The regular spiral flute with a 9xD flute-to-diameter ratio provides efficient chip evacuation during through-hole and blind-hole drilling operations. The bright, uncoated finish makes it suitable for use with standard cutting fluids. It ships individually and is sold as a single unit.

• Meets DIN 338 specification for consistent dimensional accuracy

Compatibility

Designed as a general-purpose OEM-style jobber drill for use in standard straight-shank drill chucks across drill presses, hand drills, and CNC machining centers capable of accepting a 7.50 mm shank diameter. Rated for steel, aluminum, and non-ferrous workpiece materials per material codes P, M, K, N, and S.

Installation Notes

Installation and use should follow standard machinist practice. Ensure the drill press or machine spindle is powered down and the chuck is fully secured before beginning setup. Use appropriate cutting fluid or coolant for the workpiece material to maximize tool life. Do not exceed the recommended drilling depth of 2.7165 inches without retracting to clear chips.
