Eagle Cutting Tool C300-019-D Cobalt Jobber 19/64 in

Product Description

The EAGLE CUTTING TOOL C300-019-D is a 19/64 inch cobalt jobber-length drill bit manufactured in the USA. Cobalt construction provides increased heat and wear resistance compared to standard high-speed steel, making this bit suited for drilling stainless steel, cast iron, hardened alloys, and other tough materials encountered in trade and industrial applications. The jobber-length geometry balances reach and rigidity for general-purpose through-hole and entry drilling in both hand-held and drill-press setups.

This bit is appropriate for electricians, plumbers, HVAC technicians, and mechanical contractors who regularly drill through hard substrates such as structural steel, pipe flanges, and equipment enclosures. The 19/64 inch diameter is commonly used for bolt clearance holes and cable or conduit entry points in ferrous and non-ferrous materials. Domestic manufacture supports consistent quality and tolerance control across the cutting edge and flute geometry.

Key Features

• 19/64 inch diameter cobalt construction for superior heat resistance during prolonged drilling
• Jobber-length design balances drilling depth with bit rigidity
• Suitable for stainless steel, cast iron, and hardened alloy drilling
• Manufactured in the USA

Compatibility

Designed for use in standard 3-jaw drill chucks compatible with jobber-length twist bits. No specific model or system compatibility data was provided for this SKU.

Installation Notes

Cobalt drill bits should be installed in a properly tightened chuck before use and run at appropriate spindle speeds for the material being drilled. Use cutting fluid or oil when drilling ferrous metals to extend bit life and reduce heat buildup. Secure workpieces firmly before drilling to prevent movement. Follow applicable OSHA and shop safety guidelines when operating drilling equipment.
