Eagle Cutting Tool C304-125-D Cobalt Jobber Drill Size 25

Product Description

The EAGLE CUTTING TOOL C304-125-D is a size 25 cobalt jobber-length drill bit manufactured in the USA. Cobalt construction gives this bit greater heat resistance and hardness compared to standard high-speed steel, making it a reliable choice when drilling through tough materials such as stainless steel, cast iron, hard alloys, and other abrasion-resistant workpieces. The jobber-length flute profile balances reach and rigidity for general-purpose drilling in fabrication shops, mechanical rooms, and field service applications. This bit is used by HVAC technicians, pipefitters, electricians, and general trade professionals who need consistent, accurate hole sizing across a range of metal substrates.

The C304-125-D is suited for use in standard drill presses, hand drills, and right-angle drills commonly found in trade and shop environments. Its size 25 designation makes it appropriate for thread-clearance holes, pilot holes, and precision fits where hole diameter must be held to a consistent tolerance. This bit ships in a quantity of one, allowing single-piece procurement for replacement or spot use without requiring a full set purchase.

Key Features

• Cobalt construction for superior heat resistance during high-speed or hard-material drilling
• Jobber-length flute for a balance of reach and bit rigidity
• Size 25 wire gauge designation for precise hole sizing
• USA manufactured for consistent dimensional quality
• Compatible with standard drill chucks found on hand drills and drill presses

Compatibility

Designed as a general-purpose cobalt jobber drill bit compatible with standard keyed and keyless drill chucks used in portable and bench-mounted drilling equipment across HVAC, plumbing, electrical, and mechanical trade applications.

Installation Notes

This drill bit is installed by trade professionals using standard hand drills, drill presses, or right-angle drills. Ensure the workpiece is securely clamped or fixtured before drilling to prevent movement and maintain hole accuracy. Use appropriate cutting fluid or lubricant when drilling hard metals to extend bit life and reduce heat buildup. Inspect the cutting edges before each use and replace the bit if chipping or dulling is observed.
