Precision Twist Drill 010024 Hss Jobber Drill Bit 3/8 in

Product Description

The PRECISION TWIST DRILL 010024 is a high-speed steel (HSS) jobber-series drill bit engineered for drilling into hard surfaces under extreme heat and force conditions. With a 3/8-inch tip diameter, a 4-inch depth of cut, and a 5-inch overall length, this bit is built to maintain cutting geometry and edge integrity across repeated use in demanding applications. The HSS construction provides the toughness needed for production drilling environments where heat buildup and mechanical stress are constant factors. It is the go-to choice for machinists, maintenance technicians, and trade professionals who need reliable performance in a standard jobber format.

This drill bit is suited for use in metalworking, fabrication, and general maintenance applications where a 3/8-inch hole is required in steel, cast iron, and other hard materials. The jobber-length format makes it compatible with standard drill presses, hand drills, and magnetic-base drills commonly found on job sites and in machine shops. It is sold as an individual unit, making it practical for targeted replacement or single-task use without committing to a full set.

Key Features

• HSS construction withstands elevated cutting temperatures and mechanical stress
• 3/8-inch tip diameter for standard-size hole production
• 4-inch depth of cut accommodates common stock thicknesses
• 5-inch overall length fits standard three-jaw chucks and drill press setups
• Jobber-series format for broad compatibility with handheld and bench-mounted drilling equipment

Compatibility

Designed as an OEM-style jobber drill bit suitable for use in standard 3/8-inch or larger keyed and keyless drill chucks on portable drills, drill presses, and magnetic-base drilling machines.

Installation Notes

Installation and use should be performed by a qualified machinist or skilled tradesperson familiar with drilling operations. Ensure the drill bit is fully seated and secured in the chuck before operation, and confirm the workpiece is clamped or fixtured to prevent movement. Apply appropriate cutting fluid when drilling ferrous metals to manage heat and extend bit life. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.
