Cleveland C11610 Jobber Drill Bit 13/64 in Hss

Product Description

The CLEVELAND C11610 is a jobber-length drill bit designed for precision drilling in high-speed steel (HSS) with a bright, uncoated finish. It measures 13/64 inch (0.2031 inch) in diameter with a 135-degree split-point tip that reduces walking and improves centering on contact. The overall length is 3-5/8 inches, and the flute length is 2-7/16 inches. This is a heavy-duty grade bit built to NAS 907 Type B standards, making it appropriate for production shops, maintenance facilities, and trade professionals who demand consistent, tight-tolerance results on repetitive drilling operations.

This bit is optimized for use in aluminum as its primary workpiece material, though its HSS construction suits a range of general-purpose drilling tasks. The right-hand spiral flute with web-thinned, tapered web configuration promotes efficient chip evacuation and reduces thrust during drilling. It fits standard drill chucks accepting a straight-cylindrical shank of 0.2031 inch diameter. Machinists, maintenance technicians, and fabrication professionals working in HVAC, plumbing, and electrical trade contexts will find this bit suited for sheet metal, light structural aluminum, and general metalwork drilling.

Installation Notes

Installation and use should be performed by qualified machinists or trade professionals familiar with rotary cutting tools and drill press or hand-drill operation. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before beginning any drilling operation. Disconnect power to any electrically driven equipment before changing or inspecting bits. Do not exceed the rated speed range for the workpiece material or bit diameter.
