Eagle Cutting Tool 1090-047-I Hss Drill Bit 47/64 in

Product Description

The EAGLE CUTTING TOOL 1090-047-I is a 47/64-inch high speed steel (HSS) screw machine (stub length) drill bit with a 1/2-inch reduced shank. Designed for metal drilling applications in production and maintenance environments, this stub-length drill offers greater rigidity than jobber-length bits, reducing deflection and improving hole accuracy in tight setups. The 1/2-inch shank allows it to seat in standard 1/2-inch drill chucks and milling machine collets. Licensed machinists, tool and die workers, maintenance technicians, and HVAC fabricators commonly use stub-length HSS drills when working in confined spaces or when extra rigidity is required.

This drill bit is suited for drilling ferrous and non-ferrous metals including mild steel, aluminum, and copper, as well as plastics and composite materials. The screw machine stub-length geometry keeps the bit short and stiff, making it a reliable choice for drill press work, CNC setups, and hand-held drill motor applications where a standard jobber bit would flex or chatter. It is an import-grade bit appropriate for general shop use and high-cycle production runs where cost-per-hole efficiency matters.

Key Features

• 47/64-inch cutting diameter in high speed steel construction
• Stub screw machine length for maximum rigidity and reduced deflection
• 1/2-inch reduced shank fits standard 1/2-inch drill chucks and collets
• HSS material provides heat resistance suitable for drilling steel and non-ferrous metals
• Import grade — cost-effective option for general production and maintenance drilling

Compatibility

Designed as a screw machine stub-length replacement drill bit compatible with any drill press, mill, or hand drill equipped with a 1/2-inch or larger chuck capacity.

Installation Notes

Installation is performed by machinists, tool and die technicians, or maintenance trades. Secure the 1/2-inch shank fully in the chuck and tighten all jaws evenly before operation. Use appropriate cutting fluid or lubricant when drilling steel to extend bit life and maintain hole quality. Inspect the cutting edges for wear or chipping before each use and replace the bit if the edge is degraded to avoid workpiece damage or unsafe operation.
