Eagle Cutting Tool S304-107-I Cobalt Jobber Drill Size 7

Product Description

The EAGLE CUTTING TOOL S304-107-I is a size 7 cobalt jobber-length drill bit designed for general-purpose drilling in metal and other hard materials. Cobalt construction provides heat resistance and edge retention when cutting through ferrous metals, stainless steel, and other tough workpiece materials. The jobber-length geometry offers a practical balance of reach and rigidity, making it a standard choice for machinists, pipefitters, and maintenance technicians who drill frequently in production or field environments.

This drill bit is suited for use in both portable hand-held drills and bench-mounted drill presses. Size 7 corresponds to a specific fractional or wire gauge diameter in the numbered drill series, making it a common selection for clearance holes, tap drilling, and precision hole sizing in metal fabrication and mechanical assembly applications. It is typically used by machinists, industrial maintenance technicians, and trade professionals working in HVAC, plumbing, and electrical installations where metal drilling is required.

Key Features

• Cobalt steel construction for improved heat resistance and extended tool life in hard materials
• Jobber-length design provides standard reach suitable for most general drilling tasks
• Size 7 numbered drill fits standard drill chucks and drill press setups
• Suitable for drilling ferrous metals, stainless steel, and other hard materials

Compatibility

Designed as a standard size 7 jobber-length drill bit compatible with typical 3-jaw drill chucks on portable drills and drill presses accepting numbered drill series bits.

Installation Notes

Cobalt drill bits should be installed securely in a properly tightened drill chuck before use. Always wear appropriate eye protection when drilling. Use cutting fluid or coolant when drilling hard metals to extend bit life and improve hole quality. Ensure the workpiece is firmly clamped before beginning any drilling operation.
