Eagle Cutting Tool S304-115-I Cobalt Jobber Drill Size 15

Product Description

The EAGLE CUTTING TOOL S304-115-I is a size 15 cobalt jobber-length drill bit designed for general-purpose drilling in demanding materials. Cobalt construction gives this bit greater heat resistance and edge retention compared to standard high-speed steel, making it well suited for drilling through harder metals, stainless steel, cast iron, and abrasive alloys. Jobber-length geometry provides a balanced combination of reach and rigidity for everyday drilling tasks on the shop floor or in the field. Qualified tradespeople and machinists reach for cobalt bits when standard HSS tooling falls short.

This drill bit is appropriate for use in metalworking, mechanical contracting, fabrication, and maintenance applications where harder base materials require more durable tooling. It is compatible with standard drill presses, hand drills, and portable magnetic drills that accept straight-shank bits. The size 15 designation corresponds to the wire gauge drill size series, commonly used in precision metalworking and HVAC sheet metal fabrication.

Key Features

• Cobalt construction for improved heat resistance and longer tool life in hard metals
• Jobber-length design balances reach and rigidity for general drilling tasks
• Size 15 wire gauge sizing fits standard precision drilling applications
• Compatible with standard straight-shank drill chucks
• Suitable for ferrous and non-ferrous metals, stainless steel, and abrasive alloys

Compatibility

Designed as a standard jobber-length straight-shank drill bit suitable for use in any drill press, hand drill, or portable drill accepting wire gauge size 15 tooling.

Installation Notes

This bit is installed by qualified tradespeople, machinists, or mechanical contractors using a standard keyed or keyless drill chuck. Secure the shank fully in the chuck before operation and confirm the workpiece is clamped or fixtured to prevent movement. Use appropriate cutting fluid on hard metals to extend tool life and reduce heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
