Precision Twist Drill 5995515 7/32 in Hss Drill Bit

Product Description

The PRECISION TWIST DRILL 5995515 is a jobber-length drill bit ground to a 118-degree standard point angle from high-speed steel (HSS) with a bright, uncoated finish. It cuts in the left-hand direction, making it well suited for extracting broken fasteners and reverse-thread applications where a right-hand bit would drive the fastener deeper. The straight shank measures 7/32 inch (0.2188 inch) in diameter and seats directly into standard drill chucks. With an overall length of 3.75 inches and a flute length of 2.5 inches, this Series L10 bit handles general-purpose drilling through steel and cast iron in a compact, easy-to-control package.

This bit is intended for drilling steel, cast iron, and similar ferrous materials in trade and industrial settings. Its left-hand cutting direction is especially useful for machinists, maintenance mechanics, and HVAC or electrical tradespeople who need to back out broken bolts or studs without a screw extractor. The regular spiral flute and tapered web with web-thinning geometry support consistent chip evacuation. It is sold individually and conforms to ANSI jobber-length standards, fitting into any standard 3/8-inch or larger drill chuck.

Key Features

• Left-hand cut removes broken fasteners and reverse-threaded hardware without driving them deeper
• 118-degree standard point angle suits general-purpose drilling in steel and cast iron
• HSS construction with bright uncoated finish for use in a wide range of ferrous materials
• Web-thinned tapered web reduces thrust and improves chip flow at the cutting tip
• Straight shank fits standard drill chucks with no adapter required
• ANSI-compliant jobber-length dimensions for consistent fitment in common tool holders

Compatibility

Designed as a general-purpose jobber-length drill bit suitable for use in standard drill chucks accepting a 7/32-inch straight shank. Primary workpiece materials are steel and cast iron per ANSI material codes P, M, K, N, and S.

Installation Notes

Install the straight shank fully into the drill chuck and tighten securely before use. De-energize and lock out any powered equipment before using this bit for fastener extraction. When drilling into cast iron or hardened steel, use cutting fluid and controlled feed pressure to extend bit life and prevent tip overheating. Left-hand bits require a drill or driver set to reverse rotation to function correctly.
