Value Collection 01165166 Letter E Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01165166 is a Letter E jobber-length drill bit machined from high speed steel (HSS) with a bright, uncoated finish. Sized at 0.2500 inch (1/4 inch) diameter, it features a standard 118-degree point angle and a regular spiral flute with a right-hand cutting direction. The bit measures 4 inches overall length with a 2.75-inch flute length, giving it the extended reach typical of jobber-length tooling. A tapered web configuration with web thinning reduces thrust requirements and improves chip evacuation. Licensed trades and machining professionals install this bit for general-purpose hole-making operations.

This drill bit is rated for use in aluminum and non-ferrous workpiece materials, making it a reliable choice for HVAC sheet metal, plumbing rough-in on copper or aluminum stock, electrical panel fabrication, and general light-industrial applications. The straight cylindrical shank measures 0.2500 inch in diameter, fitting standard three-jaw drill chucks and keyless chucks commonly found on corded and cordless drills and drill presses. The general-purpose HSS grade handles intermittent production runs and job-site use without specialized coating requirements.

Installation Notes

Installation of this bit should be performed by a qualified tradesperson or machinist familiar with rotating cutting tools. Secure the shank fully in the chuck and verify the bit runs true before beginning a cut. Always wear appropriate eye protection and ensure the workpiece is clamped or fixtured before drilling. No coolant-through capability is present; apply cutting fluid externally when drilling non-ferrous metals to extend bit life and improve finish quality.
