Eagle Cutting Tool SC404-129-D Cobalt Stub Drill Size 29

Product Description

The EAGLE CUTTING TOOL SC404-129-D is a size 29 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 in demanding drilling applications. The cobalt construction offers superior heat resistance and hardness retention, making this bit well suited for drilling harder materials including stainless steel, cast iron, high-strength alloys, and hardened steels. This drill is a professional-grade cutting tool intended for use by machinists, pipefitters, electricians, HVAC technicians, and other tradespeople who require reliable performance in production or field environments.

The SC404-129-D is designed for applications where a standard jobber-length drill may flex or walk, particularly in tight spaces or when drilling into hard or abrasive materials. The stub format pairs well with drill presses, milling machines, and hand-held power drills where chuck clearance or work envelope is limited. USA manufacture indicates domestic production standards for geometry and heat treatment consistency.

Key Features

• Cobalt construction for high heat resistance and hardness retention in difficult materials
• Stub-length design provides increased rigidity and reduced bit deflection
• Size 29 wire gauge diameter for precise hole sizing
• USA manufactured for consistent geometry and quality control
• Compatible with standard drill chucks on hand-held and bench-mounted equipment

Compatibility

Designed as a wire gauge size 29 stub drill suitable for use in standard drill presses, milling machines, and portable power drills equipped with appropriately sized chucks.

Installation Notes

Stub drills are installed and operated by machinists and tradespeople following standard machine shop or field drilling practices. Ensure the drill bit is fully seated and securely tightened in the chuck before operation. Use appropriate cutting fluid or lubricant when drilling hard or abrasive materials to extend tool life. Always wear appropriate eye protection and secure the workpiece before drilling.
