Eagle Cutting Tool C304-110-D Cobalt Jobber Drill Size 10

Product Description

The EAGLE CUTTING TOOL C304-110-D is a size 10 cobalt jobber-length drill bit manufactured in the USA. Cobalt construction makes this bit well suited for drilling hard and abrasive materials, including stainless steel, cast iron, titanium, and hardened alloys that would quickly dull standard high-speed steel bits. The jobber-length flute profile balances reach and rigidity, making it a practical choice for general-purpose drilling across a wide range of trade applications. HVAC, plumbing, electrical, and mechanical contractors keep cobalt jobbers on hand for sheet metal, structural steel, and heavy-gauge work where tool life matters.

This drill bit is appropriate for use in both hand-held and drill-press applications across residential and light commercial job sites. Its size 10 designation fits standard jobber-length applications where a consistent, clean hole is required in ferrous and non-ferrous metals. Tradespeople working with thick-gauge steel enclosures, unistrut, pipe hangers, or structural members will find this bit a reliable choice for daily production drilling.

Key Features

• Cobalt construction for extended tool life in hard and abrasive materials
• Jobber-length flute for a balance of reach and rigidity
• Size 10 designation for consistent hole sizing in standard applications
• Made in the USA
• Minimum order quantity of 1, available as a single unit

Compatibility

Designed as a standard jobber-length drill bit compatible with 3-jaw keyed or keyless drill chucks that accept the shank diameter corresponding to a size 10 wire gauge drill.

Installation Notes

Cobalt drill bits should be installed in a properly sized and tightened chuck before operation. Always secure the workpiece and wear appropriate eye protection when drilling. Use cutting fluid or lubricant when drilling hard ferrous metals to reduce heat buildup and extend bit life. Ensure drill speed is set appropriately for the material being drilled, as excessive RPM in hard materials will shorten tool life.
