Eagle Cutting Tool S300-030-I Cobalt Jobber Drill 15/32

Product Description

The EAGLE CUTTING TOOL S300-030-I is a 15/32-inch cobalt jobber-length drill bit designed for demanding metal drilling applications. Cobalt construction gives the bit superior heat resistance compared to standard high-speed steel, making it suitable for drilling hard and abrasive materials including stainless steel, cast iron, and hardened alloys. The jobber-length body provides a versatile reach appropriate for most general production and maintenance drilling tasks. Electricians, HVAC technicians, plumbers, and general tradespeople regularly reach for cobalt jobber bits when working through structural steel, unistrut, equipment enclosures, and heavy-gauge sheet metal.

This drill bit is suited for both shop and field use wherever a 15/32-inch hole is required through hard ferrous and non-ferrous metals. Typical applications include drilling pilot holes through steel channel, enlarging knockouts in electrical enclosures, drilling through pipe flanges, and general fabrication work. The bit is compatible with standard drill chucks on corded and cordless drills as well as drill presses and magnetic base drills commonly used by trades on commercial and residential job sites.

Key Features

• Cobalt construction provides elevated heat resistance for drilling hard and abrasive metals
• 15/32-inch diameter for applications requiring a precise oversized hole beyond standard fractional sizes
• Jobber-length geometry balances reach and rigidity for general-purpose drilling
• Compatible with standard chuck sizes used on portable drills and drill presses
• Minimum order quantity of 1 — available as a single unit for replacement or spot needs

Compatibility

Designed as an OEM-style replacement or standard-specification cobalt jobber drill bit suitable for use in any drill press or handheld drill with a chuck capacity accommodating a 15/32-inch shank.

Installation Notes

Secure the bit firmly in the chuck and verify there is no runout before beginning. Use appropriate cutting fluid or oil when drilling hard metals to extend bit life and reduce heat buildup. Always wear eye protection and secure the workpiece before drilling. Disposal of worn or broken bits should follow applicable shop safety procedures for sharp metal waste.
