Precision Twist Drill 5999080 Jobber Drill Bit 22 Hss

Product Description

The PRECISION TWIST DRILL 5999080 is a jobber-length drill bit in Number 22 wire size, measuring 0.1570 inches in diameter, 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 standard 118-degree split point, a spiral regular flute, and a straight-cylindrical shank. Overall length is 3.125 inches with a flute length of 2 inches. The tapered web and web-thinned geometry reduce walking and improve chip evacuation. This bit is sized and toleranced to ANSI standards and is suited for use in hand drills, drill presses, and CNC machines by machinists, maintenance technicians, and fabricators.

This jobber-length drill bit is intended for drilling through steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Its 13xD flute-to-diameter ratio and 2-inch maximum drilling depth make it well suited for through-hole and blind-hole work in sheet metal, structural steel, and machined components. The straight-cylindrical shank fits standard three-jaw chucks without adapters, making it a straightforward drop-in for most portable and benchtop drilling setups in industrial, commercial, and field maintenance applications.

Key Features

• Number 22 wire size, 0.1570-inch diameter for precise hole sizing
• 118-degree standard point angle with web-thinned, tapered web geometry for reduced entry force
• High-speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium
• Bright uncoated finish — suitable for general-purpose use and easy visual inspection of wear
• Right-hand cut, 2-flute spiral configuration for efficient chip removal
• ANSI-compliant tolerances, Series R10P-R15P-R18P

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard three-jaw drill chuck accepting a 0.1570-inch straight-cylindrical shank. Suitable for use in hand drills, drill presses, and CNC drilling operations across metalworking applications.

Installation Notes

Installation and use of this drill bit is performed by machinists, maintenance technicians, and fabricators using standard drill chucks. Secure the shank fully in the chuck and verify concentricity before starting. Use appropriate cutting fluid or coolant when drilling hard materials such as stainless steel, superalloys, or titanium to extend tool life. Allow the bit to cool before handling after extended use, and inspect the cutting edges for wear between uses.
