Eagle Cutting Tool S300-027-I Cobalt Jobber Drill 27/64

Product Description

The EAGLE CUTTING TOOL S300-027-I is a 27/64 inch cobalt jobber-length drill bit designed for metal drilling applications in industrial and trade environments. Cobalt construction provides increased heat resistance and hardness compared to standard high-speed steel bits, making this drill suitable for cutting through stainless steel, cast iron, titanium, and other hard or abrasive materials. The jobber-length geometry delivers a balanced combination of reach and rigidity for general-purpose hole-making in production and maintenance settings. Machinists, pipefitters, fabricators, and maintenance technicians regularly reach for cobalt jobber drills when standard HSS bits wear prematurely.

This drill bit is suited for use in drill presses, hand drills, and CNC machines where a 27/64 inch diameter through-hole or pilot hole is required. Common applications include structural fabrication, mechanical assembly, and maintenance repair operations involving ferrous and non-ferrous metals. The jobber-length design fits standard drill chucks and is a practical everyday cutting tool on the shop floor or in the field.

Key Features

• Cobalt construction for enhanced heat resistance and extended tool life in hard-metal drilling
• 27/64 inch diameter for precise hole sizing in mechanical and fabrication applications
• Jobber-length geometry balances reach and rigidity for general-purpose use
• Compatible with standard drill press and hand drill chucks
• Suitable for drilling stainless steel, cast iron, and other abrasive metals

Compatibility

Designed as an OEM-style replacement or direct-use cobalt jobber drill for standard 3-jaw drill chucks accepting 27/64 inch shank diameters in drill presses, hand drills, and CNC drilling equipment.

Installation Notes

Install and secure the drill bit firmly in the chuck before operation. Always wear appropriate eye protection when drilling. Ensure the workpiece is clamped securely to prevent movement during cutting. Use cutting fluid or lubricant when drilling hard metals to reduce heat buildup and extend bit life.
