Cleveland C11677 Jobber Drill Bit No 23 Hss 135 Degree

Product Description

The CLEVELAND C11677 is a jobber-length drill bit in wire gauge size No. 23, with a decimal diameter of 0.1540 inches. Made from high-speed steel with a bright uncoated finish, it features a 135-degree split point and a web-thinned, tapered web configuration for reduced thrust and faster penetration. The two-flute spiral design promotes efficient chip evacuation. This is a heavy-duty grade bit built to NAS 907 Type B standards, making it a reliable choice for production drilling applications where precision and consistency are required. Machinists, tool-and-die workers, and maintenance technicians are the primary users.

This bit is designed for use in a straight-cylindrical chuck on benchtop drill presses, CNC drilling machines, and hand-held power drills. It is well-suited for drilling aluminum and other non-ferrous metals where a sharp, free-cutting edge and accurate hole size are critical. The 1.0-inch flute length and 3.125-inch overall length are appropriate for standard-depth holes in sheet stock, castings, and structural components. It ships individually but is subject to a minimum order quantity of 12 units.

Key Features

• Wire gauge size No. 23 with a decimal diameter of 0.1540 inches
• 135-degree split point reduces walking and lowers drilling thrust
• Web-thinned, tapered web for easier chip clearing and less heat buildup
• High-speed steel construction with bright uncoated finish
• NAS 907 Type B standard compliance for consistent manufacturing tolerances
• Straight-cylindrical shank fits standard drill chucks without adapters

Compatibility

Designed as a heavy-duty jobber-length replacement or production bit for applications requiring a No. 23 wire gauge diameter hole. Primary workpiece material is aluminum per manufacturer specification. Fits any standard drill chuck accepting a 0.1540-inch straight-cylindrical shank.

Installation Notes

Install in a clean, properly tightened drill chuck before powering the machine. Verify spindle speed is appropriate for the workpiece material and bit diameter before beginning the cut. Secure the workpiece firmly to prevent movement during drilling. Do not force the bit through material; allow the split point and flute geometry to do the work to avoid premature wear or breakage.
