Eagle Cutting Tool S300-031-I Cobalt Jobber Drill 31/64

Product Description

The EAGLE CUTTING TOOL S300-031-I is a 31/64-inch cobalt jobber-length drill bit designed for high-performance drilling in hard and abrasive materials. Cobalt construction provides superior heat resistance compared to standard high-speed steel, making this bit suitable for drilling stainless steel, cast iron, titanium, and other tough metals. Trade professionals in HVAC, plumbing, electrical, and general fabrication rely on cobalt bits when standard HSS bits fail to hold an edge. The jobber-length configuration offers a practical balance between reach and rigidity for general-purpose hole-making on the job site or in the shop.

This drill bit is well-suited for use in residential and commercial trade applications where harder base materials are encountered. Typical uses include drilling through structural steel, thick pipe flanges, electrical enclosures, and mechanical equipment frames. The 31/64-inch diameter makes it a useful size when bolt clearance holes or stepped-diameter fits are required. It is compatible with standard drill chucks found on corded drills, drill presses, and magnetic base drills.

Key Features

• Cobalt construction for improved heat resistance and extended tool life in hard metals
• 31/64-inch diameter for precision clearance and stepped-fit drilling applications
• Jobber-length body balances reach and rigidity for general-purpose use
• Compatible with standard keyed and keyless drill chucks
• Minimum order quantity of 1 for flexible procurement

Compatibility

Designed for use with standard drill chucks on corded electric drills, drill presses, and magnetic base drilling machines commonly used in trade and fabrication work.

Installation Notes

This drill bit is installed and operated by trade professionals including HVAC technicians, pipefitters, electricians, and ironworkers. Ensure the drill bit shank is fully seated and secured in the chuck before operation. Use appropriate cutting fluid or lubricant when drilling through hard metals to extend bit life and improve hole quality. Always wear appropriate personal protective equipment and follow applicable workplace safety standards when operating drilling equipment.
