Precision Twist Drill 015019 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 015019 is a high-speed steel (HSS) jobber-series drill bit engineered for drilling into hard materials where heat resistance and edge retention are critical. With a tip diameter of 0.3480 inches and a depth of cut reaching 4 inches, this bit handles deep-hole applications that shorter general-purpose bits cannot reach. The overall length is 4-7/8 inches. HSS construction allows the cutting edge to maintain hardness at elevated temperatures generated during aggressive drilling, making it a reliable choice for metal fabrication, mechanical contracting, and trade service work.

This jobber-series bit is suited for use in ferrous and non-ferrous metals, including steel, cast iron, aluminum, and similar hard substrates. It fits standard drill chucks accepting its shank diameter and is appropriate for corded drills, drill presses, and mag-base drills commonly used in mechanical and electrical trade applications. The 4-inch depth of cut makes it practical for through-hole work in thick plate, structural steel, and heavy-gauge materials encountered in HVAC, plumbing, and electrical rough-in work.

Key Features

• High-speed steel (HSS) construction resists heat buildup during hard-material drilling
• 0.3480 inch tip diameter for precise, consistent hole sizing
• 4 inch depth of cut accommodates through-hole work in thick stock
• 4-7/8 inch overall length provides reach without sacrificing rigidity
• Jobber-series geometry balances cutting speed and chip clearance

Compatibility

Designed as a standard HSS jobber-series drill bit for use in any drill press or handheld drill with a chuck accepting a 0.3480 inch shank diameter.

Installation Notes

Secure the workpiece firmly before drilling to prevent movement and bit deflection. Use cutting fluid or cutting oil when drilling ferrous metals to extend bit life and reduce heat. Inspect the cutting edges before each use and replace the bit if chipping or dulling is present. Follow applicable safety standards for rotating tool operation, including eye protection and secure workholding.
