Precision Twist Drill 5998333 Jobber Drill Bit 22 Hss

Product Description

The PRECISION TWIST DRILL 5998333 is a jobber-length drill bit in wire size number 22 (0.1570 inches) designed for general-purpose drilling in a wide range of metallic workpieces. Manufactured from high speed steel with a steam oxide coating, this bit features a standard 118-degree split point, a two-flute spiral configuration, and a web-thinned, tapered web design that reduces thrust at entry. Overall length is 3.125 inches with a 2-inch flute length, making it suitable for through-hole and blind-hole drilling in production and maintenance environments. A licensed HVAC tech, machinist, or maintenance professional will find this bit suited to everyday metal drilling tasks.

This bit is built for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. The straight-cylindrical shank fits standard three-jaw drill chucks on hand drills, drill presses, and CNC machining centers. With a 13xD flute-to-diameter ratio and a maximum drilling depth of 2 inches, it handles typical jobber-depth applications in light manufacturing, field service, and trade work. The bit conforms to ANSI standards and is part of the R18 series, covering the 0.1500 to 0.2000 inch decimal inch range.

Key Features

• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Two-flute regular spiral design for efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks
• ANSI-conforming general-purpose grade suitable for steel, stainless, cast iron, non-ferrous metals, superalloys, and titanium

Compatibility

Designed as a general-purpose jobber-length drill bit for use in standard three-jaw drill chucks across hand drills, drill presses, and compatible CNC machining setups. Part of the R10-R15-R18 series covering the 0.1500 to 0.2000 inch decimal inch drill bit size range.

Installation Notes

Machinists and trade professionals should secure the straight-cylindrical shank firmly in a properly sized drill chuck before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Apply appropriate cutting fluid when drilling into stainless steel, superalloys, or titanium to extend tool life. Inspect the cutting edges and point for wear before each use, as a damaged point will affect hole quality and increase the risk of bit breakage.
