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

Product Description

The EAGLE CUTTING TOOL SC400-025-I is a 25/64 inch cobalt stub drill designed for drilling operations that demand heat resistance and durability in tough materials. The stub-length body provides added rigidity compared to standard-length drills, reducing deflection during aggressive feed rates. Cobalt construction gives this bit the hardness needed to cut through stainless steel, cast iron, hard alloys, and other abrasion-resistant workpieces. Machinists, pipefitters, plumbers, and electricians reach for stub drills when working in tight clearances or when hole location accuracy is critical.

This drill is suited for use in stationary drill presses, hand-held power drills, and magnetic-base drilling setups. The 25/64 inch diameter targets applications such as bolt-clearance holes, conduit knockouts in heavier-gauge material, and pilot holes in structural steel or stainless. The stub format is particularly useful in confined spaces where a jobber-length drill would be impractical or prone to chatter.

Key Features

• Cobalt construction resists heat buildup during high-speed drilling in hard metals
• Stub-length body increases rigidity and reduces deflection compared to jobber-length drills
• 25/64 inch diameter suits bolt-clearance and structural drilling applications
• Minimum order quantity of 1 allows single-unit purchase for service trucks and job-site use

Compatibility

Designed as an OEM-style replacement or direct substitute for standard 25/64 inch cobalt stub drill bits used in trade and industrial drilling applications.

Installation Notes

Secure the bit firmly in the chuck before use and verify the chuck key is removed prior to powering the drill. Use cutting fluid or coolant when drilling stainless steel or hard alloys to extend bit life and reduce work-hardening at the cut surface. Inspect the cutting edges before each use and replace the bit if chipping or dullness is observed, as a damaged cobalt drill can fracture under load.
