Cleveland C11706 Jobber Drill Bit No. 52 Hss 135 Deg

Product Description

The CLEVELAND C11706 is a jobber-length drill bit sized to wire gauge No. 52 (0.0635 inches diameter), designed for precision drilling in metalworking and fabrication applications. Built from high-speed steel (HSS) with a bright, uncoated finish, this bit features a 135-degree split-point tip that self-centers on contact and reduces walking on hard or smooth surfaces. The two-flute spiral design with a regular helix and web-thinned, tapered web provides efficient chip evacuation. Overall length is 1.875 inches, with a flute length of 0.875 inches and a straight-cylindrical shank. It meets NAS 907 Type B standards and is rated heavy-duty grade. Licensed HVAC technicians, machinists, and trade professionals performing precision drilling on aluminum and similar materials rely on this bit for consistent, accurate results.

The C11706 is suited for drilling aluminum as its primary workpiece material, making it a practical choice for HVAC sheet-metal work, electrical panel fabrication, and general light-metal drilling tasks. The No. 52 wire-gauge size is commonly specified in precision instrument work, electronics assembly, and small-fastener pilot-hole applications. The straight-cylindrical shank accepts standard drill chucks without adapters, and the compact jobber length fits most handheld and benchtop drill setups where a short, rigid bit is preferred over a longer twist drill.

Compatibility

Designed as an OEM-style jobber-length drill bit suitable for standard drill chucks accepting a 0.0635-inch straight-cylindrical shank; primary workpiece material is aluminum per manufacturer specification.

Installation Notes

This bit is installed and operated by machinists, electricians, HVAC technicians, and general trade professionals using standard handheld or benchtop drill equipment. Secure the straight-cylindrical shank firmly in a keyed or keyless chuck before use. Use appropriate cutting fluid or lubrication when drilling aluminum to extend bit life and maintain bore quality. Wear eye protection and secure the workpiece before drilling to prevent movement and breakage of this small-diameter bit.
