Eagle Cutting Tool SC400-027-D Cobalt Stub Drill 27/64

Product Description

The EAGLE CUTTING TOOL SC400-027-D is a 27/64-inch cobalt stub drill designed for metal drilling applications in demanding shop and field environments. The stub-length body provides added rigidity compared to jobber-length drills, reducing deflection and improving hole accuracy in tough or interrupted cuts. Made in the USA, this drill bit suits machinists, pipefitters, and maintenance technicians who need consistent performance when drilling steel, stainless, cast iron, and other hard materials. The cobalt construction allows the bit to retain cutting edge hardness at elevated temperatures generated during heavy-duty drilling.

This stub drill is suited for use in drill presses, lathes, and hand-held power drills where a shorter flute length is preferred for stability. Common applications include metal fabrication shops, mechanical contractors, and industrial maintenance settings where holes in the 27/64-inch range are frequently required. The stub-length format is especially useful when working in confined spaces or when the workpiece demands minimal bit flex.

Key Features

• 27/64-inch diameter for precise, repeatable hole sizing
• Cobalt construction retains hardness under high cutting temperatures
• Stub-length body reduces flex and deflection for improved accuracy
• Manufactured in the USA
• Compatible with standard drill chucks and drill press setups

Compatibility

Designed as an OEM-style replacement or direct-use cobalt stub drill suitable for standard 3/8-inch or 1/2-inch keyed and keyless drill chucks accepting 27/64-inch shanks.

Installation Notes

Secure the bit firmly in the drill chuck before operation and verify the chuck key is removed prior to powering the tool. Use cutting fluid or coolant when drilling hard metals to extend bit life and maintain edge integrity. Machinists and maintenance technicians should follow applicable shop safety standards and wear appropriate eye protection during all drilling operations. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
