The EAGLE CUTTING TOOL C304-108-D is a cobalt jobber-length drill bit designed for demanding drilling applications in metal, stainless steel, cast iron, and other hard materials. Cobalt construction provides superior heat resistance and edge retention compared to standard high-speed steel bits, making this drill a reliable choice for production and maintenance environments. Manufactured in the USA, this bit is suited for use by machinists, pipefitters, HVAC technicians, plumbers, and electricians who need a dependable tool for hole-making in tough base materials. The jobber-length flute geometry balances reach and rigidity for general-purpose drilling.
This drill is appropriate for use in residential and commercial trade applications where drilling into ferrous and non-ferrous metals is required. Common install scenarios include drilling through sheet metal, pipe flanges, electrical enclosures, strut channel, and structural steel. The cobalt alloy composition handles elevated cutting temperatures that would degrade standard HSS bits, making it well suited for use with hand-held drills, drill presses, and magnetic-base drills on job sites or in shop environments.
Designed as a general-purpose cobalt jobber drill compatible with standard three-jaw drill chucks across hand-held, bench-top, and magnetic-base drilling equipment commonly used in mechanical, electrical, and plumbing trades.
Cobalt drill bits should be installed by a qualified tradesperson familiar with proper drilling technique for the base material being worked. Always secure the workpiece before drilling and use appropriate cutting fluid or lubricant when drilling through hardened steel or stainless steel to extend bit life. Disconnect or de-energize any equipment before drilling into it, in accordance with applicable lockout/tagout procedures. Do not exceed the rated speed range for the bit diameter when operating on a drill press.
