Precision Twist Drill 5995523 Jobber Drill Bit 9/32 Hss

Product Description

The PRECISION TWIST DRILL 5995523 is a jobber-length, left-hand-cut drill bit designed for general-purpose drilling in steel, cast iron, and similar materials. Built from high-speed steel (HSS) with a bright, uncoated finish, it features a standard 118-degree point angle and a web-thinned, tapered-web tip for improved penetration and reduced thrust. The straight shank measures 9/32 inch in diameter, the overall length is 4.25 inches, and the flute length runs 2.9375 inches, supporting a maximum drilling depth of 2-15/16 inches. This bit is suited for machinists, maintenance technicians, and metalworking tradespeople who require a left-hand cutting direction for their application.

The 5995523 is intended for use in jobber-length drilling operations on steel and cast iron workpieces in both shop and field environments. The left-hand cutting direction makes it particularly useful for removing broken fasteners and extracting studs when paired with a reversible drill or left-hand drill press setup. The regular spiral flute and two-flute configuration promote efficient chip evacuation during drilling. It conforms to ANSI standards and carries a Series L10 designation, placing it within a consistent, catalog-indexed line for repeat procurement.

Key Features

• Meets ANSI standards; Series L10 for consistent catalog sourcing

Compatibility

Designed as an OEM-style general-purpose jobber-length drill bit for use with standard straight-shank drill chucks across bench drills, hand drills, and drill presses accepting a 9/32-inch shank diameter.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with metalworking equipment. Secure the straight shank firmly in a compatible drill chuck before operation and verify the drill is set to the correct rotational direction for left-hand cutting. Ensure the workpiece is properly clamped or fixtured to prevent movement during drilling. Follow applicable shop safety protocols and wear appropriate eye protection when operating any rotary cutting tool.
