Cleveland C11616 19/64 Inch Hss Jobber Drill Bit 135 Degree

Product Description

The CLEVELAND C11616 is a jobber-length twist drill bit designed for general-purpose hole-making in metal, plastics, and soft alloys. Built from high speed steel with a bright uncoated finish, it features a 135-degree split-point tip that reduces walking on entry and lowers thrust force compared to conventional 118-degree points. The bit measures 19/64 inch (0.2969 inch) in diameter with a 3-1/16 inch flute length and a 4-3/8 inch overall length. The straight-cylindrical shank seats securely in standard keyless or keyed drill chucks. This is a heavy-duty grade bit manufactured to NAS 907 Type B standards and sold individually.

The C11616 is suited for drilling aluminum and other non-ferrous metals, as well as general fabrication tasks in HVAC, plumbing, and electrical rough-in work. The regular spiral flute provides efficient chip evacuation at typical hand-drill and drill-press speeds. The web-thinned, tapered-web geometry reduces cutting resistance, making it a reliable choice for production drilling where consistent hole quality matters. This bit is part of CLEVELAND Series 2222 and is intended for professional trade use on the bench or in the field.

Key Features

• 135-degree split-point tip reduces walking and lowers feed pressure on entry
• High speed steel construction provides good hardness and heat resistance for metal drilling
• Web-thinned, tapered-web geometry reduces cutting resistance and extends tool life
• Bright uncoated finish maintains sharp cutting edge geometry out of the box
• Straight-cylindrical shank fits standard 3/8-inch and 1/2-inch drill chucks
• Meets NAS 907 Type B specification for dimensional and performance consistency

Compatibility

Designed as a jobber-length replacement or working bit for standard drill chucks accepting a straight-cylindrical shank; rated primarily for aluminum and non-ferrous workpiece materials per NAS 907 Type B specification.

Installation Notes

A licensed tradesperson or qualified mechanic should select drill speed appropriate to material hardness and bit diameter before use. Secure the workpiece firmly before drilling and use cutting fluid when drilling ferrous metals to extend bit life. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point shows heat discoloration or edge rollover. Coolant-through drilling is not supported on this bit.
