Precision Twist Drill 015024 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 015024 is a high-speed steel (HSS) jobber-series drill bit engineered for drilling into hard materials in demanding trade applications. With a tip diameter of 0.3970 inches and a depth of cut reaching 4 inches, this bit delivers the reach needed for through-hole work in thick stock. The overall length of 5.125 inches fits standard three-jaw chucks on corded and cordless drill presses and hand drills alike. HSS construction resists heat buildup and edge wear, making this bit a reliable choice for machinists, electricians, plumbers, and HVAC technicians who drill through metal, hardened plastics, and similar substrates regularly.

This jobber drill bit is suited for light industrial and commercial trade use where consistent hole geometry and bit longevity matter. Typical applications include drilling pilot holes, clearance holes, and through holes in ferrous and non-ferrous metals, structural components, and mechanical assemblies. It is well matched for use in shop environments, fabrication work, and field service situations where a general-purpose HSS bit of this diameter range is called for.

Key Features

• High-speed steel construction for heat and wear resistance in hard-material drilling
• 0.3970 inch tip diameter for precise, consistent hole sizing
• 4 inch depth of cut accommodates thick workpieces and deep through-hole applications
• 5.125 inch overall length fits standard drill chucks without adapters
• Jobber-series geometry provides a balance of rigidity and chip clearance

Compatibility

Designed as a general-purpose HSS jobber drill bit compatible with standard three-jaw drill chucks on bench-top drill presses, magnetic drills, and handheld power drills that accept straight-shank bits in this diameter range.

Installation Notes

This bit is installed by a machinist, electrician, plumber, or general trade technician using a drill press or handheld drill with a compatible chuck. Secure the workpiece before drilling and use appropriate cutting fluid when drilling through ferrous metals to extend bit life and maintain hole quality. Inspect the cutting edges before each use and replace the bit if chipping or dullness is detected. Follow applicable shop safety practices including eye and hand protection.
