Precision Twist Drill 5999160 Drill Bit Wire 26 Hss

Product Description

The PRECISION TWIST DRILL 5999160 is a jobber-length drill bit sized to wire gauge 26, with a decimal diameter of 0.1470 inches. It is machined from high-speed steel (HSS) with a bright, uncoated finish and features a standard 118-degree split-point tip with a web-thinned, tapered web design. The spiral flute geometry promotes chip evacuation during through-hole and blind-hole drilling operations. Overall length is 3 inches, with a 1-7/8-inch flute length and a straight-cylindrical shank. This bit is sold individually and is suited for professional machinists, maintenance technicians, and trade contractors requiring consistent, repeatable hole sizing.

This drill bit is designed for general-purpose drilling in a wide range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its compact jobber-length profile makes it appropriate for benchtop drill presses, hand-held electric drills, and CNC drilling operations where controlled depth and straight entry are required. The right-hand spiral cut and 13xD flute-to-diameter ratio support efficient chip removal across these material types. It conforms to ANSI standards and is part of the R10P-R15P-R18P series.

Key Features

• Wire gauge size 26 with a decimal diameter of 0.1470 inches for precise hole sizing
• High-speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium
• 118-degree standard point angle with web-thinned, tapered web for reduced entry force
• Bright uncoated finish suitable for general-purpose shop use without additional surface treatment
• Right-hand spiral flute with 13xD ratio for reliable chip evacuation up to 1-7/8 inches maximum drilling depth
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard three-jaw drill chucks accepting a 0.1470-inch straight-cylindrical shank. Conforms to ANSI specification and fits drill presses, hand drills, and CNC machines configured for straight-shank tooling in this diameter range.

Installation Notes

Installation is performed by machinists or trade technicians using a standard keyed or keyless drill chuck. Secure the shank fully in the chuck and verify concentricity before commencing drilling. Always wear appropriate eye protection and secure the workpiece before operation. Follow applicable shop safety standards and machine manufacturer guidelines for feed rate and RPM selection based on workpiece material.
