Eagle Cutting Tool SC404-147-D Cobalt Stub 47 Drill

Product Description

The EAGLE CUTTING TOOL SC404-147-D is a size 47 cobalt stub drill manufactured in the USA. Stub drills, also called screw machine length drills, feature a shorter flute and overall length compared to jobber-length bits, which increases rigidity and reduces deflection in high-cycle drilling applications. The cobalt construction improves heat resistance and cutting performance when working through harder materials such as stainless steel, cast iron, and high-strength alloys. This bit is suited for machinists, pipefitters, electricians, and HVAC technicians who require consistent, accurate hole sizing in demanding shop or field conditions.

This drill is used in drill presses, CNC machines, and hand-held power drills where a short, stiff cutting tool is preferred. The size 47 wire gauge designation corresponds to a specific small-diameter bore used in precision drilling tasks, including pilot holes, tap preparation, and close-tolerance work across metalworking, mechanical, and trade service applications. Domestic USA manufacture supports consistent dimensional tolerances and material certification.

Key Features

• Cobalt construction for improved heat resistance and extended tool life in hard materials
• Stub length design increases rigidity and minimizes deflection during drilling
• Size 47 wire gauge diameter for precision small-bore applications
• USA manufactured for consistent dimensional tolerances
• Compatible with standard drill chucks used in hand drills, drill presses, and CNC equipment

Compatibility

Designed as an OEM-style replacement or standard supply for any drill press, hand-held power drill, or CNC spindle accepting wire gauge size 47 stub drill bits with a standard straight shank.

Installation Notes

Secure the bit firmly in the chuck and verify zero runout before beginning a drilling operation. Use appropriate cutting fluid or coolant when drilling hard metals to preserve edge life. Disconnect or de-energize equipment before changing bits. Drilling into pressurized or energized components must follow applicable trade codes and lockout/tagout procedures.
