Cleveland C73474 Jobber Drill Bit No. 46 0.0810 in Hss

Product Description

The CLEVELAND C73474 is a No. 46 wire gauge jobber length drill bit designed for precision hole-making in metal fabrication and production drilling applications. Built from high speed steel with a bright uncoated finish, this bit features a 118-degree split point that reduces walking and lowers thrust on entry. The straight-cylindrical shank measures 0.0810 inches in diameter, matching the nominal drill diameter, and the two-flute spiral design with a regular spiral type clears chips efficiently during through-hole drilling. At 0.1 pounds, this is a lightweight, single-piece bit suited for use in standard drill chucks and CNC spindles.

This bit is rated for primary use on aluminum and similar non-ferrous materials, making it a practical choice for aerospace sheet metal work, light manufacturing, and production line drilling. The web-thinned, tapered web configuration reduces cutting resistance, which is particularly useful when drilling thin-walled aluminum stock. The bit meets NAS 907 Type A standards, indicating suitability for aerospace and defense fabrication environments where dimensional tolerances are tightly controlled. Licensed tradespeople and production machinists working to NAS specifications will find this bit fits standard workflow requirements.

Key Features

• No. 46 wire gauge size, 0.0810 inches decimal diameter with a tight tolerance of -0.0005 to 0.0000 inches
• 118-degree split point reduces bit walking and decreases required thrust force on entry
• High speed steel construction rated for heavy duty drilling applications
• Web-thinned, tapered web design lowers cutting resistance for cleaner holes
• Bright uncoated finish compatible with cutting fluid use on aluminum and non-ferrous materials
• Meets NAS 907 Type A specification for aerospace-grade dimensional compliance

Compatibility

Designed for use in standard straight-shank drill chucks and CNC spindles accepting a 0.0810-inch shank. Primary workpiece material is aluminum; the NAS 907 Type A specification makes this bit appropriate for aerospace and defense fabrication drilling operations.

Installation Notes

This drill bit is installed and operated by machinists, tool-and-die workers, and sheet metal fabricators using drill presses, hand drills, or CNC drilling equipment. Secure the straight-cylindrical shank fully in the chuck before operating to prevent runout. Apply appropriate cutting fluid when drilling aluminum to extend bit life and maintain hole quality. Inspect the cutting edges and split point for wear or chipping before each use, and replace the bit when diameter tolerance can no longer be held.
