Precision Twist Drill 015013 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 015013 is a high-speed steel (HSS) jobber-series drill bit engineered for drilling into hard materials where heat resistance and edge durability are critical. With a tip diameter of 0.2950 inches and a depth of cut reaching 4 inches, this bit handles deeper bores without sacrificing concentricity. The full length measures 4.375 inches. HSS construction allows the cutting edge to retain hardness at elevated temperatures, making it suitable for ferrous metals, hardened plastics, and other tough substrates. Licensed tradespeople and shop machinists reach for jobber-length bits as the go-to general-purpose drilling tool across a wide range of materials and applications.

This jobber drill bit is appropriate for use in professional trade and industrial settings where consistent hole quality in hard surfaces is required. Typical applications include metalworking, mechanical fitting, HVAC bracket fabrication, electrical panel work, and general maintenance drilling on structural components. The 0.2950-inch diameter corresponds closely to a letter or number drill size, making it useful when a precise hole diameter is needed prior to tapping or reaming. Sold individually as a single unit, it fits standard drill chucks compatible with this shank diameter.

Key Features

• High-speed steel (HSS) construction retains cutting-edge hardness under high heat and pressure
• 0.2950-inch tip diameter for precise, repeatable hole sizing
• 4-inch depth of cut supports deeper bores in a single pass
• 4.375-inch overall length in the standard jobber-length format
• General-purpose geometry suitable for ferrous metals, hard plastics, and similar materials

Compatibility

Designed as a standard jobber-length HSS drill bit compatible with any drill press, hand drill, or driver chuck sized to accept a 0.2950-inch shank diameter.

Installation Notes

Installation of this bit should be performed by qualified tradespeople familiar with proper drilling technique for the target material. Secure the workpiece firmly before drilling and ensure the chuck is fully tightened before operating. Use appropriate cutting fluid when drilling ferrous metals to extend bit life and improve hole quality. Inspect the cutting edges for wear or chipping before each use and replace the bit if the edge shows signs of heat damage or dulling.
