Value Collection 01220300 Jobber Drill Bit 15/32 in Hss

Product Description

The VALUE COLLECTION 01220300 is a left-hand, high-speed steel jobber drill bit designed for precision drilling in metal fabrication and machining applications. It measures 15/32 inches (0.4688 inches) in diameter with a 118-degree standard point angle and a bright, uncoated finish. The 5-3/4 inch overall length and 4-5/16 inch regular spiral flute provide solid chip evacuation during left-hand cutting operations. Web-thinned with a tapered web configuration, this bit reduces thrust requirements at entry. It is a general-purpose bit suited for production and maintenance drilling in steel and cast iron. Machinists and metalworking technicians are the primary installers and users.

This jobber drill bit is intended for use in left-hand cutting applications, which makes it particularly useful when extracting broken fasteners or when counter-rotation setups are required. It is a general-purpose grade bit suited for drilling into steel and cast iron in both production shop environments and field maintenance scenarios. The straight cylindrical shank seats directly into standard drill chucks and collets. It ships individually and is sold as a single unit.

Installation Notes

Installation and use should be performed by a qualified machinist or metalworking technician familiar with drill press, lathe, or hand-drill operation. Always secure the workpiece firmly and confirm the machine spindle rotation matches the left-hand cutting direction of this bit before operating. Inspect the cutting edges for wear or damage before each use, and replace the bit if chipping or dullness is observed. Follow applicable shop safety standards and wear appropriate eye and hand protection during all drilling operations.
