Cleveland C73416 5/16 Inch Hss Jobber Drill Bit

Product Description

The CLEVELAND C73416 is a jobber-length twist drill bit designed for precise hole-making in metal fabrication, mechanical assembly, and general trade work. Built from high-speed steel with a bright uncoated finish, this bit measures 5/16 inch (0.3125 inch) in diameter and 4.5 inches overall length. The 118-degree split point reduces walking at the start of a cut and lowers thrust requirements compared to a conventional point. The tapered web with web thinning further improves chip evacuation and cutting efficiency. Rated as heavy duty and conforming to NAS 907 Type A standards, this bit suits demanding production and field applications alike.

The C73416 is suited for drilling aluminum and similar non-ferrous materials, though its high-speed steel construction handles mild steel and other common workpiece materials in typical trade settings. The straight-cylindrical shank accepts standard three-jaw drill chucks on corded or cordless tools. Its regular spiral flute and right-hand cut make it a straightforward drop-in for jobber-length applications in HVAC, plumbing, electrical rough-in, and light fabrication work where a 5/16-inch bore is required.

Installation Notes

Install this bit into a properly rated drill chuck and tighten with a chuck key before operation. Secure the workpiece firmly before drilling to prevent movement. Follow applicable OSHA and shop safety guidelines including eye protection when drilling metal. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is visible.
