Eagle Cutting Tool S304-117-I Cobalt Jobber Drill No 17

Product Description

The EAGLE CUTTING TOOL S304-117-I is a Number 17 cobalt jobber-length drill bit designed for drilling through hard metals, stainless steel, cast iron, and other tough materials that wear out standard high-speed steel bits. Cobalt construction provides superior heat resistance, allowing the bit to maintain cutting-edge integrity at elevated temperatures generated during heavy-duty drilling. This bit is suited for trade professionals including HVAC technicians, pipefitters, electricians, and plumbers who regularly drill into hardened or abrasive materials on the job site or in the shop.

The S304-117-I is sized to Number 17 wire gauge drill dimensions, making it appropriate for applications requiring precise hole diameters in metal fabrication, conduit work, pipe fitting, and mechanical assembly. Jobber-length geometry provides a balance between reach and rigidity, reducing deflection during drilling. This bit works with standard drill chucks on corded or cordless electric drills and drill presses.

Key Features

• Cobalt construction for extended performance in hard and abrasive metals
• Number 17 wire gauge sizing for precise hole diameter control
• Jobber-length flute design balances reach with bit rigidity
• Compatible with standard drill press and handheld electric drill chucks
• Minimum order quantity of 1 unit

Compatibility

Designed as a general-purpose cobalt jobber drill bit suitable for use with standard drill presses and handheld electric drills accepting wire gauge Number 17 drill bits.

Installation Notes

Cobalt drill bits should be used at appropriate drill speeds for the material being drilled — lower RPM settings are typically required for harder metals to prevent overheating and premature edge wear. Apply cutting fluid or threading oil when drilling ferrous metals to extend bit life and improve cut quality. Secure the workpiece firmly before drilling to prevent movement and bit breakage. Discard bits that show visible chipping or excessive wear rather than attempting to redress without proper grinding equipment.
