Eagle Cutting Tool C304-146-D Cobalt Jobber Drill Size 46

Product Description

The EAGLE CUTTING TOOL C304-146-D is a size 46 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 suited for drilling into harder workpiece materials including stainless steel, cast iron, and high-nickel alloys. The jobber-length configuration offers the standard flute-to-shank ratio familiar to machinists and metalworking professionals, balancing reach and rigidity for general-purpose drilling operations in shop and field environments.

This drill bit is intended for use in metalworking, fabrication, and maintenance applications where a size 46 wire-gauge diameter is required. It fits standard drill chucks used in drill presses, hand drills, and machining centers. Machinists, pipefitters, fabricators, and maintenance technicians typically reach for cobalt jobber drills when working through materials that would wear out standard HSS tooling prematurely.

Key Features

• Cobalt construction for improved heat resistance and extended tool life in hard materials
• Size 46 wire-gauge diameter for precise hole sizing
• Jobber-length geometry balances reach with rigidity
• Manufactured in the USA

Compatibility

Designed as a standard wire-gauge jobber drill compatible with conventional drill chucks used in drill presses, handheld power drills, and machining centers that accept the shank diameter of a size 46 drill bit.

Installation Notes

Secure the bit firmly in a properly sized drill chuck before operation and verify the chuck is fully tightened. Use appropriate cutting fluid or coolant when drilling hard metals to extend tool life and maintain hole quality. Always wear eye protection and secure the workpiece before drilling. Dispose of worn tooling properly and inspect bits for chipping or cracking before each use.
