Eagle Cutting Tool 1090D-051-I Drill Bit 51/64 in

Product Description

The EAGLE CUTTING TOOL 1090D-051-I is a 51/64-inch jobber-length drill bit designed for high-volume metal removal in professional trade and industrial applications. Built with a straight 1/2-inch shank, it seats securely in standard chucks and drill presses without slipping under load. The split-point geometry of the Dyno SD design reduces walking at entry, allowing faster starts on metal, wood, and composite materials without a center punch. This bit is manufactured to import tolerances and is suited for machinists, fabricators, maintenance technicians, and contractors who need reliable hole-making performance at a practical cost.

The 1090D-051-I is intended for use in drill presses, magnetic drills, and heavy-duty hand drills where a 1/2-inch chuck capacity is available. The 51/64-inch cutting diameter is commonly used in structural and mechanical fabrication work where close-tolerance holes are required for fasteners, pins, or clearance fits. This bit is appropriate for both shop and field use across HVAC, plumbing, electrical, and general construction trades.

Key Features

• 51/64-inch cutting diameter for close-tolerance hole sizing in metal and composite materials
• 1/2-inch straight shank compatible with standard drill press and hand drill chucks
• Split-point tip design reduces entry walking and improves start accuracy
• Jobber-length body provides a balance of reach and rigidity for general-purpose drilling
• Import construction offers cost-effective performance for high-use and expendable tool applications

Compatibility

Designed for use in any drill press, magnetic drill, or hand drill accepting a 1/2-inch shank bit. Suitable for drilling metal, wood, and composite substrates in standard trade and fabrication environments.

Installation Notes

Licensed trades including electricians, plumbers, and HVAC technicians typically install drill bits of this size during rough-in work. Secure the shank fully in the chuck and verify tightness before operation. Always wear appropriate eye and hand protection when drilling metal or structural materials. Reduce feed pressure as the bit breaks through to avoid grab or bit damage.
