Eagle Cutting Tool SC404-158-D Cobalt Stub Drill

Product Description

The EAGLE CUTTING TOOL SC404-158-D is a cobalt stub-length drill bit manufactured in the USA. Cobalt construction gives this bit superior heat resistance and edge retention compared to standard high-speed steel, making it well suited for drilling into hard or abrasive materials. The stub-length body provides increased rigidity over jobber-length bits, reducing deflection and improving hole accuracy in tight workspaces or when using a drill press. At 0.1 pounds, this is a lightweight single-piece cutting tool designed for professional use in metalworking and fabrication applications.

This stub drill is used in applications where rigidity and precision matter, including drilling into stainless steel, hardened alloys, cast iron, and other tough materials that would wear down standard twist drills quickly. The shortened flute length limits side flex, which is especially useful when drilling in confined areas or performing spot work on a drill press or milling machine. It is well suited for HVAC, plumbing, electrical, and general fabrication tradespeople who regularly drill through metal structural members, mounting plates, or equipment housings.

Key Features

• Cobalt construction provides heat resistance and extended tool life in hard materials
• Stub-length design reduces deflection for improved hole accuracy
• USA manufactured for consistent quality and dimensional accuracy
• 5/8 inch diameter suits a wide range of metal drilling tasks
• Rigid body works well with drill presses and milling setups

Compatibility

Designed as a standard stub-length cobalt drill bit compatible with any drill press, milling machine, or hand drill accepting a 5/8 inch shank or used with an appropriate chuck size.

Installation Notes

Installation of this bit should be performed by a qualified tradesperson following standard machining safety practices. Secure the bit firmly in the chuck before operation and confirm the workpiece is properly clamped. Use appropriate cutting fluid or coolant when drilling hard metals to extend bit life and reduce heat buildup. Power down and de-energize all equipment before changing or inspecting bits.
