Eagle Cutting Tool C304-118-D Cobalt Jobber Drill No 18

Product Description

The EAGLE CUTTING TOOL C304-118-D is a Number 18 cobalt jobber-length drill bit manufactured in the USA. Cobalt construction provides increased heat and wear resistance compared to standard high-speed steel, making it a dependable choice for drilling into harder ferrous metals, stainless steel, and abrasive alloys. The jobber-length flute geometry balances reach with rigidity for general-purpose production drilling. This bit is used by machinists, pipefitters, electricians, HVAC technicians, and other trade professionals who require a durable drill for everyday metal drilling tasks.

The C304-118-D is suited for use in portable drills, drill presses, and multi-spindle setups in both shop and field environments. Number 18 wire gauge sizing makes it appropriate for applications requiring precise undersized holes prior to tapping, reaming, or close-tolerance fastener clearance work in light industrial and mechanical service settings.

Key Features

• Cobalt steel construction for improved heat resistance during high-speed metal drilling
• Jobber-length flute design balances reach with bit stability
• Number 18 wire gauge diameter for precision hole sizing and tap-ready applications
• USA manufactured for consistent dimensional tolerances
• Compatible with standard drill chucks in portable and stationary drilling equipment

Compatibility

Designed as an OEM-style replacement or direct-use cobalt jobber drill suitable for standard drill press chucks and hand drill applications requiring a Number 18 wire gauge drill bit.

Installation Notes

Secure the bit firmly in the chuck before operation and verify runout before drilling production holes. Use appropriate cutting fluid when drilling hardened or stainless steel to extend bit life and reduce heat buildup. Always wear eye protection and follow applicable shop safety standards when operating drilling equipment.
