Eagle Cutting Tool SC400-019-I Cobalt Stub Drill 19/64

Product Description

The EAGLE CUTTING TOOL SC400-019-I is a 19/64 inch cobalt stub drill designed for high-speed metal drilling in demanding trade and industrial applications. The stub-length flute geometry provides added rigidity over standard jobber-length bits, reducing deflection and improving hole accuracy in tough materials. Cobalt construction delivers superior heat resistance compared to standard high-speed steel, making this drill a reliable choice for cutting through hardened steel, stainless steel, cast iron, and other abrasion-resistant metals. Machinists, pipefitters, and fabricators working in HVAC, plumbing, and mechanical trades commonly reach for cobalt stub drills when standard bits fall short.

This stub drill is suited for use in drill presses, magnetic base drills, and hand-held power drills in both shop and field environments. The 19/64 inch diameter fits common applications where a standard jobber-length bit lacks the rigidity needed to maintain a clean, accurate bore. It is appropriate for light production work, maintenance and repair operations, and precision hole placement in metal plate, structural steel, and pipe fittings. Minimum order quantity is 1 unit.

Key Features

• Cobalt steel construction for heat resistance and extended tool life in hard metals
• Stub-length flute design increases rigidity and reduces bit deflection
• 19/64 inch diameter for precise sizing in mechanical and fabrication work
• Compatible with standard drill chucks on hand drills and drill presses
• Suited for drilling stainless steel, hardened steel, cast iron, and similar materials

Compatibility

Designed as a general-purpose stub-length cobalt drill for use in standard 3-jaw drill chucks across hand-held, bench, and floor drill press applications where a 19/64 inch bore diameter is required.

Installation Notes

Install the bit securely in a properly sized chuck and verify chuck key is removed before operation. Use cutting fluid or coolant when drilling hardened or stainless steel to extend bit life and reduce heat buildup. Always wear appropriate eye protection and secure the workpiece before drilling. Follow applicable shop safety standards and manufacturer guidelines for drill press speed settings based on material type and bit diameter.
