Eagle Cutting Tool SC400-025-D Cobalt Stub Drill 25/64

Product Description

The EAGLE CUTTING TOOL SC400-025-D is a 25/64 inch cobalt stub drill designed for demanding drilling applications where standard high-speed steel bits fall short. Built in the USA, this stub-length drill features a 135-degree split point geometry that reduces walking on entry and cuts through hard or abrasive materials with less feed pressure. The shorter flute and body length of the stub design provide increased rigidity compared to jobber-length drills, making it well suited for work in confined spaces or on heavy-gauge material where deflection is a concern. Cobalt construction improves heat and wear resistance, extending tool life in stainless steel, hardened alloys, and cast iron.

This drill is used across machining, fabrication, maintenance, and repair environments where hard or tough materials are regularly encountered. Machinists, toolmakers, and maintenance technicians reach for cobalt stub drills when working with stainless steel, high-nickel alloys, titanium, and similar work-hardening metals. The stub length makes it a practical choice for drill press work, CNC operations, or hand-held drilling in tight clearance situations. USA manufacture supports consistent dimensional tolerances and material certification where job specs require domestic tooling.

Key Features

• 25/64 inch diameter cobalt construction for heat and wear resistance in hard materials
• 135-degree split point reduces drill walk and lowers required feed force at entry
• Stub length provides added rigidity and reduced deflection versus jobber-length drills
• Manufactured in the USA for consistent tolerances and material traceability
• Minimum order quantity of 1, suitable for single-bit replacement or toolroom stocking

Compatibility

Designed as a standard stub-length cobalt drill for use in drill presses, CNC machining centers, and hand-held drilling equipment that accept round-shank bits sized at 25/64 inch diameter.

Installation Notes

Secure the bit firmly in a keyed or keyless chuck, verifying concentricity before beginning a cut. Use appropriate cutting fluid or coolant when drilling stainless steel or other work-hardening alloys to manage heat buildup and extend tool life. Inspect the cutting edges for wear or chipping before each use and replace when the split point shows signs of dulling. Follow shop safety protocols including eye protection and secure workpiece fixturing whenever operating drill equipment.
