Cleveland C73450 Jobber Drill Bit No. 22 Hss 118

Product Description

The CLEVELAND C73450 is a jobber-length drill bit sized at No. 22 wire gauge (0.1570 inches diameter) and manufactured from high-speed steel with a bright, uncoated finish. It features a 118-degree split point for accurate starting and reduced walking on entry, paired with a web-thinned, tapered web for lower thrust requirements. The regular spiral flute with a 2-inch flute length evacuates chips efficiently during through-hole and blind-hole operations. Designed for right-hand cutting, this bit runs in standard drill chucks with no adapter needed. At 3.125 inches overall length, it fits standard jobber-length drill applications on drill presses, CNC machines, and hand-held power drills. It meets NAS 907 Type A standards and is rated as a heavy-duty grade bit.

This bit is suited for production and maintenance drilling in aluminum as its primary workpiece material, though its HSS construction handles a range of non-ferrous and softer ferrous materials in light to moderate-duty applications. Typical install scenarios include sheet metal fabrication, HVAC knockouts, electrical panel work, and general-purpose hole drilling where a No. 22 diameter is required. A straight-cylindrical shank with a 0.1570-inch shank diameter seats securely in keyed or keyless chucks. The bit is sold individually but carries a minimum order quantity of 12 units, making it appropriate for stocking in tool cribs or fleet service vans.

Key Features

• No. 22 wire gauge diameter — 0.1570 inches — with a diameter tolerance of -0.0007 to 0.0000 inches for consistent hole sizing
• 118-degree split point reduces walking and cutting thrust compared to a conventional chisel point
• Web-thinned tapered web lowers required feed force and extends bit service life
• Bright uncoated high-speed steel construction — no coating to chip or peel during regrinding
• Regular spiral flute at 2-inch length provides efficient chip evacuation in short to medium-depth holes
• Meets NAS 907 Type A specification — suitable for aerospace and precision manufacturing environments

Compatibility

Designed as a jobber-length replacement or stocking bit for applications requiring a No. 22 wire gauge hole. Primary workpiece material is aluminum per manufacturer specification. Compatible with any standard drill chuck accepting a 0.1570-inch straight-cylindrical shank.

Installation Notes

Secure the shank fully in the drill chuck before operation and verify the chuck key is removed before powering on. Use appropriate cutting fluid or lubricant when drilling aluminum at higher feed rates to extend bit life and improve hole finish. Inspect the split point for wear before each use — a dull or chipped point increases thrust and reduces hole accuracy. Regrinding is possible on HSS bits; maintain the original 118-degree point angle and web-thinned geometry when resharpening.
