Eagle Cutting Tool SC404-156-D Cobalt Stub Drill No. 56

Product Description

The EAGLE CUTTING TOOL SC404-156-D is a No. 56 cobalt stub drill manufactured in the USA. Stub-length drills feature a shorter flute and overall length compared to jobber-length bits, reducing deflection and improving rigidity in tight-clearance or high-feed applications. Cobalt construction provides elevated heat resistance and hardness retention, making this drill well suited for use in harder ferrous metals, stainless steel, and other abrasive materials. Machinists, pipefitters, and maintenance technicians commonly reach for stub drills when working in confined spaces or when chatter and wandering are concerns in production drilling.

This drill is appropriate for use in hand-held electric drills, drill presses, and CNC machining centers. The No. 56 wire gauge size targets small-diameter precision hole applications including tapping prep, pilot holes, and close-tolerance work in metal fabrication, mechanical assembly, and industrial maintenance settings. Its stub geometry makes it a practical choice wherever a standard jobber bit is too long to seat properly in the chuck or too flexible for the application.

Key Features

• Cobalt construction for improved heat resistance and hardness retention in tough materials
• Stub-length geometry reduces deflection and increases rigidity versus jobber-length drills
• No. 56 wire gauge size for small-diameter precision drilling
• USA manufactured
• Minimum order quantity of 1 for single-unit procurement

Compatibility

Designed as a standard No. 56 wire gauge stub drill suitable for use in drill presses, hand drills, and machining centers accepting small-shank tooling.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with rotating cutting tool safety practices. Secure the shank fully in the chuck before operation and verify spindle speed is appropriate for the material and drill diameter. Always wear appropriate eye protection when drilling. Replace the drill if chipping, burning, or excessive wear is observed on the cutting edges.
