Precision Twist Drill 015025 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 015025 is a high-speed steel (HSS) jobber-series drill bit engineered for drilling into hard materials where heat resistance and durability are critical. With a tip diameter of 0.4040 inches and a depth of cut of 4 inches, this bit handles deep-hole drilling tasks that standard general-purpose bits cannot sustain. The overall length is 5.25 inches. HSS construction allows the cutting edge to retain hardness at elevated temperatures, making it suitable for production drilling, maintenance work, and fabrication applications where bit longevity matters.

This jobber drill bit is suited for use in metalworking, mechanical contracting, and maintenance trades where drilling into ferrous and non-ferrous hard surfaces is routine. It fits standard drill chucks and is compatible with both handheld and drill-press setups. Tradespeople performing structural or mechanical work who need consistent, repeatable hole geometry will find this bit appropriate for moderate to high-duty drilling cycles.

Key Features

• High-speed steel (HSS) construction resists heat buildup during hard-surface drilling
• 0.4040 inch tip diameter for precise, consistent hole sizing
• 4 inch depth of cut supports deep-hole drilling applications
• 5.25 inch overall length fits standard drill chucks
• Jobber-series geometry balances cutting speed with edge durability

Compatibility

Designed as a standard jobber-length HSS drill bit compatible with conventional drill chucks accepting the appropriate shank diameter for this bit size.

Installation Notes

Install this bit into a properly sized drill chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Use appropriate cutting fluid when drilling hard metals to extend bit life and reduce heat. Follow applicable shop safety practices, including eye protection and securing loose clothing, whenever operating rotary cutting tools.
