Eagle Cutting Tool C300-009-D Cobalt Jobber Drill 9/64

Product Description

The EAGLE CUTTING TOOL C300-009-D is a 9/64-inch cobalt jobber-length drill bit manufactured in the USA. Cobalt construction provides elevated heat resistance and hardness compared to standard high-speed steel, making this bit suited for drilling through harder workpiece materials without premature edge wear. At 0.5 pounds, it is a compact, hand-tool-ready size appropriate for electricians, plumbers, HVAC technicians, and general tradespeople who need reliable performance in ferrous metals, stainless steel, and other demanding materials on the job site or in a shop setting.

This drill bit is used wherever a 9/64-inch diameter through-hole is required. Common applications include pilot holes for self-tapping screws, conduit knockout preparation, sheet metal fabrication, and general metal drilling tasks encountered in residential and commercial trade work. Its jobber-length profile balances reach and rigidity, making it practical across a wide range of drilling equipment including portable drills and drill presses.

Key Features

• Cobalt construction for improved heat resistance and wear performance in hard metals
• 9/64-inch diameter for precise pilot hole and fastener clearance applications
• Jobber-length profile balances reach with lateral rigidity
• USA manufactured
• Minimum order quantity of 1, suitable for single-unit replacement or restocking

Compatibility

Designed as a standard jobber-length drill bit compatible with 3/8-inch and larger keyed or keyless drill chucks on portable drills and drill presses that accept round-shank bits.

Installation Notes

Secure the bit firmly in the chuck before use and verify the chuck is fully tightened to prevent slippage. Use appropriate cutting fluid or lubricant when drilling stainless steel or hardened materials to extend bit life and reduce heat buildup. Wear appropriate eye protection per job site safety requirements. Disposal of worn or broken bits should follow applicable shop safety protocols.
