Cleveland C11687 Jobber Drill Bit No. 33 0.1130 in Hss

Product Description

The CLEVELAND C11687 is a jobber-length drill bit sized to wire gauge No. 33, with a decimal diameter of 0.1130 inches. Built from high-speed steel (HSS) with a bright, uncoated finish, it features a 135-degree split point that reduces walking on entry and lowers the thrust needed to start a hole. The right-hand spiral flute design evacuates chips efficiently during through-hole drilling. Overall length is 2.625 inches with a 1.5-inch flute length, making it suitable for standard-depth drilling applications in production and maintenance environments. This bit meets NAS 907 Type B standards and carries a heavy-duty grade rating.

The C11687 is designed primarily for drilling aluminum and other non-ferrous materials, though its HSS construction handles a range of common workpiece materials encountered in light fabrication, maintenance, and repair work. The straight-cylindrical shank seats in standard three-jaw drill chucks found on drill presses, hand drills, and CNC drilling setups. Its compact jobber length suits benchtop drill presses and portable hand tools alike. The web-thinned, tapered web construction reduces cutting resistance and improves hole quality in thin-wall and soft-metal applications.

Installation Notes

Install in a drill press or hand drill with an appropriately sized three-jaw chuck and tighten securely before operation. Disconnect or de-energize the drill before changing bits. Use appropriate cutting fluid or lubrication when drilling metals to extend bit life and maintain hole tolerance. Always wear eye protection and secure the workpiece before drilling.
