Eagle Cutting Tool S300-011-I Cobalt Jobber 11/64 in

Product Description

The EAGLE CUTTING TOOL S300-011-I is an 11/64-inch cobalt jobber-length drill bit designed for professional drilling applications in metal, stainless steel, cast iron, and other hard materials. Cobalt construction provides superior heat resistance compared to standard high-speed steel, making it well suited for high-RPM drilling where heat buildup is a concern. At 0.5 pounds, this is a lightweight, single-piece cutting tool ready for immediate use. It is typically installed and operated by machinists, pipefitters, electricians, HVAC technicians, and plumbers working in the field or in a shop environment.

The S300-011-I is suited for use in residential and commercial trade applications where precise, clean holes are required in metal substrates. The 11/64-inch diameter is a common size for pilot holes, clearance holes, and conduit or bracket work. It fits standard drill chucks found on corded and cordless drills, drill presses, and right-angle drill attachments used across the trades.

Key Features

• Cobalt construction for extended heat resistance and longer tool life in hard materials

Compatibility

Designed as a standard jobber-length drill bit compatible with any drill chuck that accepts a straight-shank bit in the 11/64-inch size range, including corded drills, cordless drills, and drill presses used across HVAC, plumbing, electrical, and general mechanical trades.

Installation Notes

Secure the bit firmly in the drill chuck before use and verify the chuck is fully tightened to prevent slippage. Use appropriate cutting fluid or lubricant when drilling through hard metals to extend bit life and reduce heat. Ensure workpieces are clamped securely before drilling to prevent movement. Inspect the cutting edge before each use and replace the bit if the edge shows signs of wear or damage.
