Eagle Cutting Tool C304-151-D Cobalt Jobber Drill Size 51

Product Description

The EAGLE CUTTING TOOL C304-151-D is a size 51 cobalt jobber-length twist drill manufactured in the USA. Cobalt construction provides increased heat resistance and edge retention compared to standard high-speed steel, making this drill well suited for harder materials and repeated use in production environments. The jobber-length body offers the balance of reach and rigidity that machinists, pipefitters, and HVAC fabricators rely on for accurate hole-making in ferrous metals, stainless steel, and other demanding substrates. This drill is appropriate for use in handheld electric drills, drill presses, and CNC equipment.

This drill is intended for professional trade use where consistent sizing and bit durability are required. Size 51 wire gauge drills are commonly used for tapping preparation, sheet metal work, and precision through-holes in light steel and alloy components. It fits applications in HVAC fabrication, plumbing rough-in work, and general mechanical assembly where tight hole tolerances matter.

Key Features

• Cobalt construction for superior heat resistance and extended tool life in hard materials
• Size 51 wire gauge diameter for precision tapping and through-hole applications
• Jobber-length body balances reach and rigidity for general-purpose drilling
• Made in the USA
• Minimum order quantity of 1 for flexible purchasing

Compatibility

Designed as an OEM-style replacement and standard-fit drill for use with any 3-jaw chuck or collet system accepting wire gauge size 51 shanks in handheld, drill press, or CNC drilling applications.

Installation Notes

Secure the bit firmly in the chuck before operation and verify the chuck key is removed prior to powering the drill. Use appropriate cutting fluid or lubricant when drilling ferrous metals to extend bit life and maintain hole quality. Ensure workpieces are clamped securely to prevent movement during drilling. Follow applicable workplace safety standards for eye protection and rotating machinery.
