Eagle Cutting Tool SC400-008-D Cobalt Stub Drill 1/8 in

Product Description

The EAGLE CUTTING TOOL SC400-008-D is a cobalt stub-length drill bit ground with a 135-degree split point for fast starting and reduced walking on hard or abrasive materials. Cobalt construction gives the bit superior heat resistance compared to standard high-speed steel, making it suitable for stainless steel, hardened alloys, cast iron, and other tough materials. The stub-length body provides added rigidity and reduces deflection in short-reach drilling applications. Manufactured in the USA, this bit is a shop-ready tool for machinists, pipefitters, plumbers, and HVAC technicians working with ferrous metals and hard stock.

The SC400-008-D is sized at 1/8 inch and is commonly used in trade and light manufacturing environments where precise, clean-entry holes are required in metal. The stub flute length reduces chatter and improves hole accuracy in hand-drill and drill-press setups alike. It is well suited for field work where shorter bit length is preferred for access in tight spaces, as well as bench work where rigidity is a priority.

Key Features

• Cobalt construction for high heat resistance and extended tool life in hard materials
• 135-degree split point for self-centering starts without a center punch in most applications
• Stub-length body reduces deflection and improves hole accuracy
• 1/8 inch diameter for standard small-hole applications in metal
• Made in the USA

Compatibility

Designed as an OEM-style replacement or direct stock bit compatible with standard 1/8 inch drill chucks on hand drills, drill presses, and CNC equipment used in trade and light manufacturing applications.

Installation Notes

Cobalt drill bits should be installed in a properly sized and tightened chuck before use. Always use appropriate cutting fluid or lubricant when drilling stainless steel or hardened alloys to extend bit life and improve finish. Secure workpieces firmly before drilling to prevent movement. Consult applicable shop safety standards and PPE requirements when operating rotary cutting tools.
