Precision Twist Drill 5998336 No 23 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5998336 is a wire gauge No 23 jobber length drill bit designed for general-purpose drilling in a wide range of ferrous and non-ferrous materials. Manufactured from high speed steel with a steam oxide coating, this bit measures 3.125 inches overall length with a 2-inch spiral flute and a straight-cylindrical shank diameter of 0.154 inches. The 118-degree standard point angle and web-thinned, tapered web construction support accurate starting and efficient chip evacuation. Licensed trades and experienced machinists reach for this style of bit when drilling at moderate depths in production or service environments.

This bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium in both shop and field applications. The regular spiral flute and right-hand cut make it compatible with standard drill press and handheld drill driver setups. It fits into the Series R10, R15, and R18 family, covering the 0.1500 to 0.2000 inch decimal inch size range. Typical use cases include sheet metal work, fabrication, and mechanical assembly where a No 23 wire gauge diameter is specified.

Installation Notes

Installation is performed by machinists, maintenance technicians, and trade professionals using a standard drill press or portable drill with a keyed or keyless chuck sized for a 0.154-inch shank. Secure the shank fully in the chuck before operation and confirm the workpiece is clamped or fixtured. Inspect the cutting edges for wear or chipping before each use, and replace the bit if the point is damaged to avoid workpiece damage or bit breakage.
