Eagle Cutting Tool 1090-043-I Hss Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1090-043-I is a 43/64-inch High Speed Steel (HSS) Silver and Deming drill bit with a reduced 1/2-inch straight shank. Silver and Deming bits feature a full-size cutting diameter paired with a reduced shank, allowing them to fit standard 1/2-inch chuck capacity drills while drilling oversized holes that exceed the drill's chuck capacity. This bit is suited for metalworking, fabrication, and maintenance applications where large-diameter holes are required in steel, iron, aluminum, and similar materials.

This drill bit is designed for use in industrial, shop, and field environments. It is a standard import-grade HSS bit appropriate for production drilling, maintenance repair operations, and general metalworking tasks. Machinists, millwrights, fabricators, and maintenance technicians commonly use Silver and Deming bits when drilling holes larger than 1/2 inch in metal stock, plate, or structural components.

Key Features

• 43/64-inch cutting diameter for oversized hole applications
• Reduced 1/2-inch straight shank fits standard 1/2-inch drill chucks
• High Speed Steel (HSS) construction for cutting ferrous and non-ferrous metals

Compatibility

Designed for use with any drill press or handheld drill equipped with a 1/2-inch or larger chuck capacity. Suitable for drilling ferrous metals, non-ferrous metals, and plastics in standard metalworking and fabrication applications.

Installation Notes

Installation and use should be performed by qualified machinists, fabricators, or maintenance technicians familiar with drill press and power drill operation. Secure the workpiece firmly before drilling and ensure the bit is fully seated and tightened in the chuck before operation. Use appropriate cutting fluid or coolant when drilling ferrous metals to extend tool life and maintain cut quality. Follow all applicable shop safety guidelines, including eye and hand protection.
