Value Collection 81430050 5/64 in Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 81430050 is a high speed steel jobber-length drill bit designed for precision drilling in ferrous and ferrous-adjacent materials. Built to heavy-duty grade standards, it features a 135-degree split point that self-centers on contact, reducing the need for a center punch and minimizing walking on smooth surfaces. The parabolic flute geometry promotes efficient chip evacuation during deep-hole drilling passes. At 5/64 inch (0.0781 inch decimal) in diameter and 2 inches overall length, this bit is suited for tight-tolerance work in steel and cast iron. Licensed tradespeople and machinists reach for this size for pilot holes, tap preparation, and detail drilling in structural and mechanical assemblies.

This jobber drill bit is intended for use on steel and cast iron workpieces in both production and maintenance-repair-operations (MRO) environments. The straight cylindrical shank seats directly into standard drill chucks without an adapter, making it compatible with bench drills, drill presses, and hand-held power tools commonly found in HVAC, plumbing, electrical, and general fabrication shops. The bright uncoated finish keeps cost low for high-turnover tooling applications where bits are consumed at volume.

Key Features

• 135-degree split point self-centers and reduces thrust force on entry
• Parabolic flute design accelerates chip removal in deep or interrupted cuts
• High speed steel construction handles the heat generated in steel and cast iron drilling
• Web-thinned, tapered web configuration reduces cutting resistance
• Bright uncoated finish — no coating buildup to affect tolerance on small-diameter work
• Straight cylindrical shank fits standard 3-jaw drill chucks without adapters

Compatibility

Designed as a direct-fit replacement jobber drill bit for standard straight-shank drill chucks; primary workpiece materials listed by the manufacturer are steel and cast iron.

Installation Notes

A licensed machinist or qualified tradesperson should select drill speed appropriate to the workpiece material and bit diameter — small-diameter HSS bits are prone to breakage at excessive feed rates. Secure the workpiece firmly before drilling and use cutting fluid when drilling steel to extend bit life and improve hole finish. Inspect the cutting edges before each use; a chipped or dull split point will deflect under load and can snap the bit at this diameter.
