Precision Twist Drill 5995520 Drill Bit Set 15 Pc Hss

Product Description

The PRECISION TWIST DRILL 5995520 is a 15-piece jobber length drill bit set made from high speed steel with a bright, uncoated finish. The set covers a size range of 1/16 inch through 1/2 inch in 1/32-inch step increments, giving trades a broad selection in a single organized metal case. The 118-degree standard point angle suits general-purpose drilling in metal, plastic, and similar materials. Each bit features a straight shank for compatibility with standard three-jaw chucks. The Series L10 designation indicates conformance to ANSI jobber length standards, so bit geometry is consistent and predictable across the set.

This set is suited to metalworking and multipurpose drilling applications in commercial and light industrial settings. It is appropriate for HVAC technicians, plumbers, electricians, and other trade professionals who need a reliable selection of fractional sizes for sheet metal work, conduit mounting, structural drilling, and general fab tasks. The metal storage case keeps bits organized and protected during transport and repeated jobsite use. Left-hand cutting direction makes this set specifically useful for extracting broken fasteners and studs when used with a reverse-capable drill.

Key Features

• 15-piece fractional set from 1/16 inch to 1/2 inch in 1/32-inch increments
• High speed steel construction for durability in metalworking applications
• 118-degree standard point angle for general-purpose entry and chip clearance
• Left-hand cutting direction suited for broken fastener and stud extraction
• Straight shank fits standard three-jaw drill chucks
• Metal storage case included for organized transport and jobsite use
• Meets ANSI specification for jobber length geometry

Compatibility

Designed for use with standard three-jaw chucks on corded or cordless drills and drill presses. Straight shank fits common 3/8-inch and 1/2-inch chuck sizes. Left-hand cutting direction requires a reverse-capable drill for fastener extraction use.

Installation Notes

Install and remove bits only after the drill is powered off and the chuck is fully secured. Left-hand bits should be run in reverse at low speed when used for broken fastener extraction — confirm the drill is set to reverse before applying pressure. Inspect each bit for chipping or wear before use, and store in the provided case to protect cutting edges between jobs.
