Eagle Cutting Tool C304-122-D Cobalt Jobber Drill No 22

Product Description

The EAGLE CUTTING TOOL C304-122-D is a Number 22 cobalt jobber-length drill bit manufactured in the USA. Cobalt construction gives this bit the heat resistance and edge retention needed for drilling through hardened steels, stainless steel, cast iron, and other tough ferrous and non-ferrous materials. The jobber-length body provides a balanced ratio of flute length to overall length, making it a practical choice for general-purpose production drilling. Machinists, maintenance technicians, pipefitters, and fabricators reach for cobalt jobbers when standard high-speed steel bits wear prematurely on hard or abrasive workpieces.

The C304-122-D fits standard drill chucks found on drill presses, hand drills, and CNC machining centers. Number 22 wire gauge sizing is commonly specified in tap-drill charts, sheet metal work, and general fabrication where fractional sizes do not meet tolerance requirements. Its jobber-length geometry suits through-holes in plate stock, structural members, and enclosures encountered in HVAC, plumbing, and electrical trade work as well as industrial manufacturing environments.

Key Features

• Cobalt alloy construction for superior heat resistance and extended tool life on hard materials
• Number 22 wire gauge diameter for applications requiring wire-gauge drill sizing
• Jobber-length flute geometry balances reach and rigidity for general-purpose drilling
• USA manufactured to consistent dimensional tolerances
• Compatible with standard three-jaw drill chucks on handheld and stationary equipment

Compatibility

Designed as a general-purpose cobalt jobber drill for use in standard drill chucks on drill presses, hand drills, and machining centers requiring a Number 22 wire gauge drill bit.

Installation Notes

Secure the bit fully in the chuck and verify it runs true before engaging the workpiece. Always wear appropriate eye protection when drilling. Use cutting fluid or cutting oil on hard materials to extend bit life and improve hole quality. Replace bits showing signs of chipping, discoloration from overheating, or loss of cutting edge to avoid workpiece damage.
