Eagle Cutting Tool S304-127-I Cobalt Jobber Drill Size 27

Product Description

The EAGLE CUTTING TOOL S304-127-I is a size 27 cobalt jobber-length drill bit designed for general-purpose drilling in metal, stainless steel, cast iron, and other hard materials. Cobalt construction provides higher heat resistance compared to standard high-speed steel, making it suitable for demanding drilling applications where bit temperature rises quickly. The jobber-length body delivers a balance of reach and rigidity suited for most bench and hand-drill operations. Licensed tradespeople and industrial operators alike rely on cobalt drills when working through tough substrates that would quickly wear out conventional twist drills.

This drill bit is appropriate for use in fabrication shops, mechanical contracting, HVAC sheet-metal work, plumbing rough-in, and general maintenance environments. Size 27 corresponds to a wire gauge drill designation commonly used when precise hole sizing is required for tapping, fastener clearance, or instrument fittings. The import designation indicates this bit is sourced through international manufacturing channels while meeting standard jobber-series geometry.

Key Features

• Cobalt construction for improved heat and wear resistance in hard-material drilling
• Jobber-length body balances reach with lateral rigidity
• Size 27 wire gauge designation for precise hole diameter control
• Minimum order quantity of 1, suitable for single-unit replacement purchasing

Compatibility

Designed as a standard jobber-length replacement drill bit compatible with 3-jaw chucks and standard drill presses, hand drills, and CNC drilling setups that accept wire-gauge-size tooling.

Installation Notes

This bit is installed and removed by a licensed machinist, mechanical contractor, or qualified tradesperson using a standard 3-jaw chuck. Always secure the workpiece before drilling and confirm chuck tightness before operation. Use appropriate cutting fluid when drilling hard metals to extend bit life. Inspect the cutting edges for wear or chipping before each use and replace if the geometry is compromised.
