Precision Twist Drill 015010 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 015010 is a high-speed steel (HSS) jobber-series drill bit built for cutting through hard materials in demanding trade and industrial applications. With a tip diameter of 0.2770 inches and a depth of cut reaching 4 inches, this bit handles deeper bores without sacrificing cutting integrity. The HSS construction resists heat buildup and maintains edge hardness under the sustained friction and force generated when drilling through ferrous metals, hardened plastics, and similar tough substrates. It weighs 0.6 pounds and ships in single-pack quantity. Licensed tradespeople and industrial mechanics rely on this series for consistent, repeatable performance across a wide range of drilling tasks.

This jobber drill bit is suited for use in metal fabrication shops, mechanical rooms, and job-site conditions where hard-material drilling is routine. It fits standard drill chucks and drill presses that accept its shank diameter. Plumbers, pipefitters, electricians, and HVAC technicians commonly use jobber-length bits like this one when boring through structural members, equipment frames, and sheet metal assemblies. The 4-inch depth of cut accommodates through-boring in thicker stock where shorter bits fall short.

Key Features

• HSS construction resists heat and maintains cutting-edge hardness under high-friction conditions
• 0.2770 inch tip diameter for precise, consistent bore sizing
• 4 inch depth of cut handles deeper through-bores in thick stock
• 4-1/8 inch overall length fits standard jobber-length drill chucks and drill presses
• Single-pack unit — minimum order quantity of 1

Compatibility

Designed as a standard jobber-length HSS drill bit compatible with any drill press, hand drill, or magnetic drill unit accepting a matching chuck size for the 0.2770 inch shank diameter.

Installation Notes

This bit is installed and operated by machinists, pipefitters, electricians, and other licensed tradespeople using standard drill presses or portable power drills. Always secure the workpiece before drilling and use appropriate cutting fluid when boring through ferrous metals to extend bit life and reduce heat. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed. Follow applicable shop safety standards and PPE requirements when operating rotary cutting tools.
