Precision Twist Drill 5995486 Jobber Drill Bit 3/32 Hss

Product Description

The PRECISION TWIST DRILL 5995486 is a jobber-length twist drill bit designed for general-purpose drilling in metalworking and light industrial applications. Measuring 3/32 inch (0.0938 inch) in diameter with a 118-degree standard point angle, this bit is manufactured from high-speed steel (HSS) with a bright, uncoated finish. It features a left-hand cutting direction and a regular spiral flute, making it suitable for removal of broken fasteners and reverse-drilling operations where left-hand rotation is required. The overall length is 2.25 inches with a 1.25-inch flute length. Installation and use are appropriate for machinists, tool-and-die workers, and maintenance technicians.

This bit is rated for drilling in steel, cast iron, and similar ferrous and non-ferrous materials. The straight shank fits standard drill chucks without adapters. The Series L10 designation places it within PRECISION TWIST DRILL's general-purpose jobber-length line, built to ANSI standards. It is well suited for production drilling, maintenance repair operations, and shop environments where a left-hand cut bit is needed to back out stripped or broken studs and bolts.

Key Features

• Left-hand cutting direction for reverse-drill fastener extraction and broken-bolt removal
• 118-degree standard point angle with web-thinned, tapered web configuration for reduced thrust and easier starting
• HSS construction with bright uncoated finish suitable for steel and cast iron workpieces
• Regular spiral flute with 13xD flute-to-diameter ratio for efficient chip evacuation
• Straight shank at 0.0938 inch diameter fits standard drill chucks directly
• Meets ANSI specification standards; Series L10 general-purpose grade

Compatibility

Designed as an OEM-style general-purpose jobber-length drill bit compatible with standard drill chucks accepting a straight shank at 3/32 inch diameter. Primary workpiece materials include steel and cast iron.

Installation Notes

This bit is installed and used by machinists, maintenance technicians, and metalworking professionals. Secure the straight shank firmly in a drill chuck before operation and verify chuck key is removed prior to powering the drill. Because this is a left-hand cut bit, it requires a drill or driver capable of reverse rotation. Use appropriate cutting fluid or coolant for extended drilling in ferrous metals to preserve bit life and workpiece integrity.
