Eagle Cutting Tool SC404-150-D Cobalt Stub Drill Size 50

Product Description

The EAGLE CUTTING TOOL SC404-150-D is a size 50 cobalt stub drill manufactured in the USA. Stub drills, also known as screw machine length drills, feature a shorter flute and overall length compared to jobber-length bits, which increases rigidity and reduces deflection in high-precision drilling applications. The cobalt construction provides superior heat resistance and hardness retention, making it well suited for drilling harder ferrous metals, stainless steel, and heat-resistant alloys. This bit is appropriate for use in drill presses, CNC machining centers, and hand-operated power tools where a stiff, accurate hole entry is required.

This stub drill is used across metalworking, fabrication, and maintenance trades where close-tolerance holes are required in tough materials. The short length makes it a practical choice for applications with limited axial clearance or where workpiece rigidity demands reduced bit flex. It is commonly used by machinists, maintenance technicians, and fabricators working on ferrous and non-ferrous metals in both shop and field environments.

Key Features

• Cobalt construction for improved hardness and heat resistance compared to standard high-speed steel
• Stub (screw machine) length for increased rigidity and reduced deflection during drilling
• Size 50 wire gauge diameter for precision hole sizing
• Domestic USA manufacture
• Minimum order quantity of 1 for flexible purchasing

Compatibility

Designed as a wire gauge size 50 stub drill suitable for standard drill chucks accepting the corresponding shank diameter in metalworking, machining, and fabrication applications.

Installation Notes

Cobalt stub drills should be installed by qualified machinists or maintenance professionals using a properly rated drill press, CNC machine, or handheld power drill with a matching chuck. Always secure the workpiece firmly before drilling and ensure the drill bit is fully seated and tightened in the chuck before operation. Use appropriate cutting fluid when drilling hard or heat-sensitive materials to extend tool life and maintain hole quality. Disconnect or de-energize the machine before changing bits.
