Cleveland C11661 Jobber Drill Bit No 7 Hss 135 Deg

Product Description

The CLEVELAND C11661 is a jobber-length drill bit in wire gauge No. 7 (0.2010 inches diameter), designed for precision drilling in metal fabrication and light industrial applications. Built from high-speed steel with a bright uncoated finish, this bit features a 135-degree split point for fast engagement and reduced walking on entry. The web-thinned, tapered web construction lowers thrust requirements and improves chip evacuation. With an overall length of 3.625 inches and a 2.4375-inch spiral flute, it delivers consistent performance in right-hand cutting operations. Licensed HVAC techs, machinists, pipefitters, and general tradespeople reach for this bit when accurate hole placement matters.

This bit is rated as heavy duty and is particularly well-suited for drilling aluminum as its primary workpiece material, though the HSS construction handles a range of ferrous and non-ferrous metals common in trade work. The straight-cylindrical shank fits standard 3-jaw chucks and drill press spindles without modification. It is built to NAS 907 Type B standards, making it appropriate for aerospace-adjacent and precision mechanical work where dimensional tolerances are critical. Sold individually with a minimum order quantity of 12 units, making it practical for shop stock.

Key Features

• 135-degree split point reduces thrust and eliminates center-punch requirement on most metals
• Web-thinned tapered web improves chip flow and lowers heat buildup during drilling
• High-speed steel construction rated for heavy-duty use across aluminum and common metals
• Bright uncoated finish allows for easy visual wear inspection during tool life monitoring
• Meets NAS 907 Type B specification for dimensional and material conformance
• Regular spiral flute with right-hand cut — compatible with standard drill presses and hand drills

Compatibility

Designed for use with any standard drill press, hand drill, or mill with a chuck accepting a 0.2010-inch straight-cylindrical shank. Rated for aluminum as primary workpiece material per manufacturer specification.

Installation Notes

Install in a properly sized chuck and tighten securely before operation. Ensure the workpiece is clamped or fixtured to prevent movement during drilling. Apply appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life, noting this bit does not support through-coolant. Inspect the cutting edges and web area periodically — replace when chipping or dulling is observed to maintain hole tolerance.
