Cleveland C11680 Jobber Drill Bit Wire 26 Hss 135 Deg

Product Description

The CLEVELAND C11680 is a jobber-length drill bit in wire gauge size 26, with a decimal diameter of 0.1470 inches, manufactured from high-speed steel with a bright uncoated finish. Built to NAS 907 Type B standards, this heavy-duty bit features a 135-degree split point for fast engagement and reduced walking on entry. The spiral flute geometry is a regular helix with a tapered web configuration and web thinning for improved chip evacuation. Overall length is 3.0 inches with a 1-7/8-inch flute length and a straight-cylindrical shank. It is sold individually and installed by machinists, maintenance technicians, and fabricators in production or repair applications.

The C11680 is suited for drilling aluminum as its primary workpiece material, making it a practical choice in HVAC fabrication, sheet metal work, and light manufacturing where small-diameter precision holes in non-ferrous materials are required. The straight-cylindrical shank seats in standard three-jaw drill chucks on both handheld and bench-mounted drill presses. The bright uncoated finish is appropriate for aluminum and other non-ferrous materials where coated surfaces are not required.

Installation Notes

Install and remove this bit with the drill press or handheld drill fully powered off and the chuck key removed from the chuck. Secure the straight-cylindrical shank firmly in the chuck before beginning any drilling operation. Use appropriate cutting fluid or lubrication when drilling at higher feed rates to extend bit life. Follow applicable shop safety standards and wear appropriate eye protection during all drilling operations.
