Precision Twist Drill 015023 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 015023 is a high-speed steel (HSS) jobber-series drill bit designed for drilling into hard materials where heat resistance and edge retention are critical. With a tip diameter of 0.3860 inches and a depth of cut of 4 inches, this bit handles deeper bores without sacrificing concentricity or straightness. The HSS construction allows the cutting edge to maintain hardness at elevated temperatures generated during aggressive drilling in ferrous and non-ferrous metals, making it a reliable choice for production and maintenance drilling applications.

This jobber-length drill bit is suited for general-purpose drilling across metalworking, mechanical contracting, and industrial maintenance environments. The jobber-series length provides a practical balance between rigidity and reach, making it appropriate for use in standard drill presses, hand drills, and CNC equipment. It is typically installed by machinists, pipefitters, and HVAC or electrical tradespeople who require consistent hole sizing in metal substrates during fabrication or field installation work.

Key Features

• High-speed steel (HSS) construction resists heat buildup during hard-surface drilling
• 0.3860 inch tip diameter for precise, repeatable hole sizing
• 4 inch depth of cut supports deeper bore applications in a single pass
• Jobber-series length balances reach and rigidity for versatile use
• Compatible with standard drill chucks on hand drills, drill presses, and CNC spindles

Compatibility

Designed as a general-purpose HSS jobber-length drill bit suitable for use with standard three-jaw drill chucks across a range of hand-held and stationary drilling equipment.

Installation Notes

Secure the bit firmly in the chuck and verify concentricity before beginning drilling operations. Always wear appropriate eye protection and ensure the workpiece is properly clamped before applying feed pressure. Reduce feed rate and use appropriate cutting fluid when drilling hardened or thick metal stock to extend bit life and prevent premature edge failure. Inspect the cutting edges for wear or chipping before each use.
