Eagle Cutting Tool S300-017-I Cobalt Jobber Drill 17/64

Product Description

The EAGLE CUTTING TOOL S300-017-I is a 17/64 inch cobalt jobber-length drill bit designed for professional drilling applications in metal, stainless steel, cast iron, and other hard materials. Cobalt construction provides superior heat resistance compared to standard high-speed steel, making it well suited for high-speed or continuous-duty drilling where bit temperature is a concern. The jobber-length flute geometry balances reach and rigidity for general-purpose hole-making in shop, field, and maintenance environments. Electricians, plumbers, pipefitters, HVAC technicians, and mechanical contractors regularly turn to cobalt jobber bits when working through structural steel, pipe, and hardened metal components.

The S300-017-I is intended for trade professionals who need a reliable, medium-diameter drill bit for everyday metal fabrication, equipment installation, and service work. The 17/64 inch diameter is a common size used when drilling clearance holes for fasteners, conduit fittings, and pipe hangers. It is suitable for use in standard drill presses, hand drills, and mag-base drills across residential, commercial, and light industrial job sites.

Key Features

• Cobalt construction for improved heat resistance and durability in hard-material drilling
• Jobber-length flute design balances cutting reach with bit stiffness
• 17/64 inch diameter suits common fastener and fitting clearance hole requirements
• Compatible with standard drill chucks used in hand drills and drill presses
• Minimum order quantity of 1 allows single-unit procurement

Compatibility

Designed as a general-purpose cobalt jobber drill bit compatible with standard 3/8 inch and 1/2 inch keyed or keyless drill chucks on hand drills, drill presses, and magnetic-base drilling units.

Installation Notes

Cobalt drill bits should be installed securely in the chuck and tightened with a chuck key where applicable before operation. Use cutting fluid or cutting oil when drilling ferrous metals to extend bit life and reduce heat buildup. Always wear appropriate eye protection and secure the workpiece before drilling. Dispose of worn bits in accordance with local shop safety practices.
