Precision Twist Drill 015017 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 015017 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 0.3320 inches and a depth of cut of 4 inches, this bit handles deeper holes in a single pass without requiring pilot drilling in most applications. The overall length is 4.75 inches. HSS construction allows the bit to withstand the elevated temperatures and cutting forces generated when working ferrous metals, hardened plastics, and similar tough substrates. It is sold as a single unit and is well suited for use by machinists, pipefitters, electricians, and general mechanical contractors.

This jobber drill bit is appropriate for use in standard drill presses, hand-held electric drills, and magnetic base drills where a 0.3320-inch diameter hole is required. Typical applications include through-hole drilling in steel plate, pipe flanges, electrical enclosures, and structural steel members. The jobber-length design balances reach and rigidity, making it a practical choice for repetitive production drilling as well as one-off field work.

Key Features

• High-speed steel (HSS) construction resists heat buildup during hard-material drilling
• 0.3320-inch tip diameter suits a wide range of standard hole specifications
• 4-inch depth of cut allows single-pass drilling in thick stock
• 4.75-inch overall length provides a stable grip-to-cutting-zone ratio
• Jobber-series geometry balances flute length and shank rigidity for general-purpose use

Compatibility

Designed as an OEM-style jobber drill bit compatible with standard three-jaw drill chucks accepting straight-shank bits in the 0.3320-inch diameter range.

Installation Notes

Installation should be performed by a qualified machinist or tradesperson familiar with rotating cutting tools. Secure the bit fully in the chuck before operation and verify runout before beginning the cut. Always use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and reduce heat. Disconnect power to the drill press or de-energize the tool before changing bits.
