Precision Twist Drill 5999110 Wire 26 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5999110 is a jobber-length drill bit sized to wire gauge 26, equal to 0.1470 inches in diameter. It is ground from high speed steel with a steam oxide coating that reduces friction and extends service life in general-purpose drilling operations. The 135-degree split point starts on contact without a center punch, reducing walking on hard surfaces. With a 3-inch overall length and a 1.875-inch spiral flute, this bit fits standard drill chucks and is sized for production or maintenance drilling in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Licensed machinists, pipefitters, sheet metal workers, and maintenance mechanics are the primary users.

This bit is suited for drilling in ferrous and non-ferrous metals, hard materials, and superalloys in both shop and field environments. The regular spiral and tapered web configuration are optimized for general-purpose stock removal. The 2-flute design clears chips efficiently in through-hole and blind-hole applications. It conforms to ANSI standards and meets NAS 907 specification, making it appropriate for aerospace maintenance and industrial fabrication workflows where material traceability matters.

Key Features

• Wire size 26 (0.1470 inches) straight-cylindrical shank fits standard chucks without adapters
• 135-degree standard point reduces walking and improves bite on hard materials
• Steam oxide coating lowers friction and provides light corrosion resistance during storage
• Web-thinned, tapered web design reduces thrust force and extends cutting life
• Rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium
• Meets ANSI standard and NAS 907 specification for dimensional and material compliance

Compatibility

Designed as a general-purpose OEM-style jobber drill bit compatible with any standard drill chuck accepting a 0.1470-inch straight-cylindrical shank. Rated for use across material codes P, M, K, N, and S per the NAS 907 specification.

Installation Notes

Installation is performed by machinists, sheet metal workers, or maintenance mechanics using a standard keyed or keyless drill chuck. Secure the shank fully in the chuck before beginning any drilling operation and confirm the workpiece is clamped or fixtured. For best results in steel and hard materials, apply cutting fluid to reduce heat buildup and extend edge life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is visible.
