Precision Twist Drill 5996579 Jobber Drill 10mm Hss

Product Description

The PRECISION TWIST DRILL 5996579 is a 10.00 mm diameter jobber-length drill bit designed for general-purpose drilling in a wide range of materials. Built from high speed steel (HSS) with a bright/uncoated finish, it features a 135-degree split-point geometry with web thinning to reduce thrust and improve centering on entry. The right-hand spiral flute with a regular helix clears chips efficiently throughout the cut. At 5.2362 inches overall length with a 3.4252-inch flute, this bit handles drilling depths up to 3.4252 inches in a standard drill chuck or machining center.

This jobber drill is suited for use in ferrous and non-ferrous metals including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. It carries the DIN 338 standard designation, making it appropriate for production shops, maintenance facilities, and tool rooms where a reliable, heavy-duty general-purpose drill is needed. The straight-cylindrical shank at 10.00 mm diameter fits standard drill chucks without an adapter. It is sold individually and is not coolant-through capable.

Key Features

• 10.00 mm diameter with 135-degree standard point for reduced walking and self-centering on entry
• High speed steel construction with bright/uncoated finish for use across a broad material range
• Web-thinned, tapered-web design lowers cutting thrust and improves chip flow
• Regular spiral, 2-flute configuration with a 9xD flute-to-diameter ratio for deep hole clearance
• Straight-cylindrical shank fits standard drill chucks with no reduction sleeve required
• Meets DIN 338 specification for heavy-duty general-purpose jobber drills

Compatibility

Designed as a general-purpose jobber drill for use in handheld drill drivers, drill presses, CNC machining centers, and lathes equipped with a chuck or collet accepting a 10.00 mm straight shank. Rated for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium per material codes P, M, K, N, and S.

Installation Notes

Installation is performed by machinists, toolmakers, and maintenance technicians. Secure the shank fully in the chuck and verify concentricity before beginning a cut. Apply appropriate cutting fluid or coolant at the workpiece surface to extend tool life, particularly when drilling stainless steel or superalloys. Do not exceed the drill's rated flute depth of 3.4252 inches in a single pass without retracting to clear chips.
