Eagle Cutting Tool SC404-140-D Cobalt Stub Drill Size 40

Product Description

The EAGLE CUTTING TOOL SC404-140-D is a size 40 cobalt stub drill manufactured in the USA. Cobalt stub drills are shorter than standard-length twist drills, providing increased rigidity and reduced deflection when drilling into hard or abrasive materials. The stub-length body makes this drill well suited for applications where clearance is limited or where chatter and flex must be minimized. This bit is installed by machinists, maintenance technicians, and trade professionals who require a reliable, stiff cutting tool for precision hole-making in metal and other tough substrates.

The SC404-140-D is designed for use in hand-held drill motors, drill presses, and CNC machining centers. Its cobalt construction makes it appropriate for drilling stainless steel, cast iron, hardened alloys, and other materials that quickly wear standard high-speed steel bits. The stub length is particularly useful in tight workspaces or when drilling through thick stock where a longer flute would introduce unwanted vibration.

Key Features

• Cobalt construction for enhanced heat and wear resistance in hard materials
• Stub-length body increases rigidity and reduces bit deflection during drilling
• Size 40 wire gauge diameter for precision hole sizing
• Manufactured in the USA
• Minimum order quantity of 1, suitable for single-unit procurement

Compatibility

Designed as a standard stub-length cobalt drill for use in any drill chuck or collet system accepting wire gauge size 40 tooling, including hand drills, drill presses, and machining centers.

Installation Notes

This drill should be installed and operated by qualified machinists or trained trade professionals familiar with proper cutting tool handling. Secure the bit firmly in the chuck or collet before operation and confirm the workpiece is properly clamped. Use appropriate cutting fluid or coolant when drilling hard alloys to extend tool life and maintain hole quality. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
