Eagle Cutting Tool SC400-023-D Cobalt Stub Drill 23/64

Product Description

The EAGLE CUTTING TOOL SC400-023-D is a 23/64-inch cobalt stub drill manufactured in the USA. Stub-length drills feature a shorter flute and overall length compared to jobber-length bits, providing increased rigidity and reduced deflection when drilling into harder or abrasive materials. The cobalt construction gives this bit greater heat resistance than standard high-speed steel, making it well suited for demanding drilling applications in metal and alloy workpieces. Licensed tradespeople and machinists working with stainless steel, cast iron, or other tough materials will find the added rigidity and heat tolerance of this bit practical for daily use.

This drill is appropriate for use in machine shops, fabrication environments, and on job sites where shorter drill geometries improve control and accuracy. Stub drills are commonly used in drill presses, lathes, and hand-held power drills where workpiece hardness or close-quarters conditions call for a stiffer bit. The 23/64-inch diameter suits applications requiring holes just under 3/8 inch, which is a common size in metal fabrication and mechanical assembly work.

Key Features

• 23/64-inch diameter stub-length geometry for increased rigidity and reduced deflection
• Cobalt construction provides superior heat resistance compared to standard high-speed steel
• USA manufactured for consistent quality and dimensional accuracy
• Stub flute length improves performance in drill presses and tight work setups
• Suitable for drilling stainless steel, cast iron, and other hard or abrasive metals

Compatibility

Designed as a standard stub-length drill bit suitable for use in conventional drill chucks, drill presses, and CNC equipment accepting 23/64-inch round-shank tooling.

Installation Notes

This bit is installed and changed by machinists or tradespeople using standard chuck keys or toolless chuck systems. Always secure the workpiece and ensure the chuck is fully tightened before operation. Use appropriate cutting fluid when drilling hard metals to extend tool life and manage heat buildup. Inspect the cutting edges for wear or chipping before each use and replace worn bits promptly to maintain hole quality.
