Eagle Cutting Tool 1090D-116-I Dyno Bang Drill Bit

Product Description

The EAGLE CUTTING TOOL 1090D-116-I is a 1-1/4 inch Dyno Bang drill bit with a 1/2 inch shank, built for professional drilling applications in trade and industrial environments. Dyno Bang geometry is designed to deliver aggressive material removal with reduced walking on entry, making it a practical choice for repetitive drilling tasks. The 1/2 inch shank provides solid tool-holder engagement and is compatible with standard 1/2 inch drill chucks and driver setups common on heavy-duty corded and cordless drills. Licensed contractors, machinists, and trade professionals working in fabrication, installation, or field service will find this bit suited to demanding production use.

This bit is appropriate for use in residential and commercial construction, mechanical contracting, and fabrication shop environments. The 1-1/4 inch cutting diameter suits larger-bore applications such as hole-making for conduit, pipe, or structural penetrations where a standard twist bit falls short. The 1/2 inch shank keeps the bit stable at higher torque levels typical of professional-grade drill motors.
