Eagle Cutting Tool S304-114-I Cobalt Jobber Drill

Product Description

The EAGLE CUTTING TOOL S304-114-I is a cobalt jobber-length drill bit designed for drilling through ferrous metals, stainless steel, and other hard materials that standard high-speed steel bits struggle with. Cobalt construction allows the bit to retain hardness at elevated cutting temperatures, making it suitable for demanding production and field work. At 0.4 pounds, it is a lightweight tool appropriate for use in standard drill chucks and magnetic drill setups. Electricians, plumbers, HVAC technicians, and general tradespeople rely on cobalt jobber bits for punching clean holes in structural steel, brackets, and enclosures.

This drill bit is suited for use in residential and commercial construction, mechanical rooms, and fabrication environments where hard or abrasive materials are encountered. Jobber-length geometry provides a practical balance between reach and rigidity, reducing deflection in typical through-hole applications. It is appropriate for handheld drills, drill presses, and magnetic base drills. The 1/4 inch diameter makes it a common size for conduit knockouts, anchor pilot holes, and fastener clearance holes across multiple trades.

Key Features

• Cobalt construction retains cutting hardness at high operating temperatures
• Jobber-length geometry balances reach and rigidity for general-purpose drilling
• 1/4 inch diameter suits common trade applications including conduit, anchors, and fastener clearance
• Compatible with standard drill chucks and magnetic drill setups
• Lightweight at 0.4 pounds for easy handling and transport

Compatibility

Designed as a general-purpose cobalt jobber drill bit compatible with standard 3-jaw drill chucks accepting 1/4 inch shank tooling across handheld and bench-mounted drilling equipment.

Installation Notes

Installation is performed by qualified tradespeople using standard drilling equipment. Always secure the workpiece before drilling to prevent movement and ensure a clean, accurate hole. Use appropriate cutting fluid or lubricant when drilling stainless steel or hard alloys to extend bit life and improve cut quality. Inspect the cutting edges before use and replace the bit if chipping or excessive wear is observed.
