The EAGLE CUTTING TOOL C304-147-D is a No. 47 cobalt jobber-length drill bit manufactured in the USA. Cobalt construction gives this bit the heat resistance and hardness needed to drill through tough materials including stainless steel, cast iron, and hardened alloys where standard high-speed steel bits fall short. The jobber-length body provides a balance of reach and rigidity suitable for general-purpose production and maintenance drilling. Machinists, pipefitters, and maintenance technicians rely on this style of bit for everyday hole-making tasks across a wide range of ferrous and non-ferrous materials.
This bit is suited for use in machine shops, fabrication environments, and field maintenance applications. The No. 47 size is commonly used when precision small-diameter holes are required, such as for tapping operations, clearance holes, and pilot drilling. It is compatible with standard drill presses, handheld electric drills, and CNC machining centers equipped with an appropriate chuck or collet for the bit shank diameter.
Designed as an OEM-style replacement or direct-use cobalt jobber drill for standard drill presses, handheld drills, and CNC machining centers accepting wire gauge No. 47 drill bits.
A licensed machinist or qualified maintenance technician should install and operate this drill bit. Ensure the drill chuck is fully tightened and the workpiece is securely clamped before beginning any drilling operation. Use appropriate cutting fluid when drilling hard or stainless steel materials to extend bit life and reduce heat buildup. Inspect the bit for wear or chipping before each use and replace if cutting edge integrity is compromised.
