Eagle Cutting Tool C300-011-D Cobalt Jobber Drill 11/64

Product Description

The EAGLE CUTTING TOOL C300-011-D is an 11/64-inch cobalt jobber-length drill bit manufactured in the USA. Cobalt construction provides increased heat resistance and hardness compared to standard high-speed steel, making it well-suited for drilling tough materials such as stainless steel, cast iron, and hardened alloys. The jobber-length flute design offers a practical balance between reach and rigidity for general-purpose drilling tasks. Licensed tradespeople and skilled tradespeople working in fabrication, HVAC, plumbing, and electrical applications rely on cobalt drill bits when standard HSS bits wear prematurely on hard substrates.

This drill bit is intended for use in hand-held drills, drill presses, and other standard rotating tool setups across residential and commercial job sites. Its 11/64-inch diameter suits common fastener clearance holes, pilot holes, and light fabrication work encountered in mechanical, electrical, and plumbing trades. The USA manufacture designation indicates domestic production, which is a common procurement requirement on certain public and commercial projects.

Key Features

• Cobalt alloy construction for superior heat resistance and extended tool life in hard materials
• 11/64-inch diameter for common pilot and clearance hole applications
• Jobber-length flute profile balances reach and bit rigidity
• Manufactured in the USA

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard 3-jaw drill chucks in hand-held drills and drill presses accepting fractional-inch shank sizes.

Installation Notes

Install and remove drill bits only when the tool is powered off and unplugged or the battery pack is removed. Secure the bit fully in the chuck before operation to prevent slipping. Use appropriate cutting fluid or coolant when drilling hard metals to extend bit life and reduce heat buildup. Eye protection is required during all drilling operations per standard job-site safety practices.
