Cleveland C73452 Jobber Length Drill Bit No. 24 Hss

Product Description

The CLEVELAND C73452 is a jobber-length drill bit sized to No. 24 wire gauge (0.1520 inches diameter) and built for heavy-duty drilling applications. Manufactured from high-speed steel with a bright, uncoated finish, this bit features a 118-degree split point that reduces walking and lowers the thrust needed to start a hole. The spiral flute geometry is a regular right-hand configuration with web thinning applied at the tip for improved chip evacuation. Overall length is 3.125 inches, with a 2-inch flute length and a straight-cylindrical shank matching the 0.1520-inch bit diameter. It meets NAS 907 Type A specifications and is suited for installation by machinists, maintenance technicians, and skilled tradespeople working in metal fabrication or mechanical service environments.

The C73452 is designed for drilling aluminum as its primary workpiece material, though the high-speed steel construction handles a range of ferrous and non-ferrous metals in typical shop and field conditions. The jobber-length format fits standard drill chucks and is a practical choice for benchtop drill presses, hand drills, and CNC drilling operations where a No. 24 wire gauge hole is required. The tapered web configuration and web-thinned point make it particularly effective in softer metals where chip packing is a concern.

Key Features

• No. 24 wire gauge size — 0.1520 inches diameter with a tight tolerance of -0.0007 to 0.0000 inches
• 118-degree split point reduces drill walking and lowers entry thrust
• Web-thinned, tapered web construction improves chip clearance
• High-speed steel construction rated for heavy-duty service
• Bright uncoated finish — compatible with cutting fluids and oils for extended tool life
• Meets NAS 907 Type A specification — Series 2228

Compatibility

Designed as an OEM-style jobber-length replacement bit for applications requiring a No. 24 wire gauge (0.1520-inch) hole, particularly in aluminum and similar non-ferrous materials. Fits any standard straight-shank drill chuck accepting a 0.1520-inch shank.

Installation Notes

Install and remove drill bits only with the drill or drill press fully powered down and the chuck key clear of the chuck. Secure the workpiece before drilling to prevent rotation and bit breakage. Apply a compatible cutting fluid when drilling metals to manage heat and extend bit life. Inspect the cutting edges before each use — a chipped or worn split point should be resharpened or the bit replaced before resuming work.
