Eagle Cutting Tool SC404-113-D Cobalt Stub Drill 13 Piece

Product Description

The EAGLE CUTTING TOOL SC404-113-D is a cobalt stub drill bit set made in the USA. Cobalt construction provides superior heat resistance and hardness compared to standard high-speed steel, making these bits well-suited for drilling through tough materials including stainless steel, cast iron, hardened alloys, and other difficult metals. The stub-length design offers increased rigidity and reduced deflection, which improves accuracy in short-hole drilling applications. Licensed tradespeople and machinists working in HVAC, plumbing, electrical, and mechanical trades rely on stub drills for tight-clearance drilling where a standard-length bit would flex or wander.

This 13-piece cobalt stub drill set is intended for professional use in shops, fabrication environments, and field service situations where drilling into hard or abrasive base materials is required. The stub-length flute reduces chatter and increases control, particularly when working in confined spaces or drilling at angles. USA-made construction indicates compliance with domestic manufacturing standards and is often a requirement on government and commercial jobsite specifications.

Key Features

• Cobalt construction for enhanced heat resistance and durability in hard-metal drilling
• Stub-length design reduces deflection and improves hole accuracy
• 13-piece set covers a range of drill sizes for varied jobsite needs
• USA-made manufacturing supports domestic procurement and jobsite compliance requirements
• Suitable for drilling stainless steel, cast iron, hardened alloys, and similar materials

Compatibility

Designed for use with standard drill chucks and drill presses accepting stub-length twist drill bits in common trade and machining applications.

Installation Notes

Stub drill bits are installed and removed by licensed machinists, HVAC technicians, plumbers, and electricians using a standard keyed or keyless chuck. Always ensure the drill bit is fully seated and secured in the chuck before operation. Use appropriate cutting fluid when drilling through hardened or stainless materials to extend bit life and reduce heat buildup. Follow applicable shop safety standards and wear appropriate PPE including eye protection at all times.
