Precision Twist Drill 015009 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 015009 is a high-speed steel (HSS) jobber-series drill bit designed for drilling into hard materials where heat resistance and cutting durability are required. It features a 0.272-inch tip diameter and a 4-inch depth of cut, with an overall length of 4.125 inches. The HSS construction allows the bit to maintain its cutting edge under the elevated temperatures generated when working hard metals and dense alloys. This bit is a standard trade-stock item used by machinists, pipefitters, electricians, and general contractors for precision hole-making in ferrous and non-ferrous materials.

The 015009 jobber drill bit is suited for general-purpose drilling applications in residential, commercial, and light industrial settings. Its jobber-length geometry provides a balance of reach and rigidity, making it appropriate for hand-held drill use as well as drill press operation. Typical applications include drilling pilot holes, clearance holes, and through-holes in steel, cast iron, aluminum, and similar hard-surface materials encountered during mechanical and electrical installations.

Key Features

• High-speed steel (HSS) construction resists heat buildup during hard-material drilling
• 0.272-inch tip diameter for precise, repeatable hole sizing
• 4-inch depth of cut accommodates standard jobber-length drilling tasks
• Overall length of 4.125 inches suits both handheld drills and drill presses
• Jobber-series geometry balances reach and lateral rigidity

Compatibility

Designed as a standard jobber-length HSS drill bit compatible with any 3-jaw or keyed chuck accepting a straight shank at the specified diameter.

Installation Notes

Installation of this drill bit should be performed by a qualified tradesperson familiar with rotary cutting tools and appropriate workholding methods. Secure the workpiece firmly before drilling and ensure the chuck is fully tightened before operation. Use appropriate cutting fluid or lubricant when drilling hard ferrous metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or dullness is observed.
