Eagle Cutting Tool S304-110-I Cobalt Jobber Drill Bit

Product Description

The EAGLE CUTTING TOOL S304-110-I is a size 10 cobalt jobber-length drill bit designed for general-purpose drilling in metal, stainless steel, cast iron, and other hard materials. Cobalt construction provides increased heat resistance compared to standard high-speed steel, making it suitable for demanding drilling applications where friction and elevated temperatures are factors. This bit is appropriate for use by machinists, maintenance technicians, pipefitters, and other trade professionals who require consistent performance in ferrous and non-ferrous metals. The jobber-length flute geometry offers a balanced combination of reach and rigidity for standard production and field drilling tasks.

This drill bit is suited for use in hand-held drills, drill presses, and benchtop machines across residential, commercial, and industrial environments. Typical applications include drilling pilot holes for fasteners, conduit knockouts, pipe flanges, structural steel, and sheet metal. Its cobalt composition makes it a practical choice when carbon or standard HSS bits are insufficient for the material hardness encountered on the job.

Key Features

• Cobalt construction for improved heat and wear resistance in hard-material drilling
• Jobber-length flute provides standard reach with good rigidity
• Size 10 designation for precise hole sizing in production and field work
• Compatible with standard drill chucks on hand-held and bench-mounted equipment
• Minimum order quantity of 1 for flexible procurement

Compatibility

Designed as a standard jobber-length cobalt drill bit compatible with conventional 3-jaw drill chucks used in hand drills and drill presses accepting straight-shank bits.

Installation Notes

Always secure the workpiece before drilling and ensure the drill chuck is properly tightened before operation. Use appropriate cutting fluid or lubricant when drilling hard metals to extend bit life and improve hole quality. Wear proper eye and hand protection in accordance with applicable shop safety standards. Inspect the cutting edges for wear before each use and replace the bit if chipping or dullness is observed.
