Eagle Cutting Tool 1090-116-I Hss Slow Down Drill Bit

Product Description

The EAGLE CUTTING TOOL 1090-116-I is a 1-1/4 inch diameter high speed steel (HSS) slow-down drill bit with a 1/2 inch reduced shank. Designed for drilling large-diameter holes in metal, wood, and similar materials, this bit is compatible with standard 1/2 inch chuck drills and drill presses. The HSS construction provides good wear resistance and heat tolerance for demanding cutting applications. Trade professionals and skilled tradespeople working in fabrication, HVAC duct work, plumbing rough-in, or general construction will find this a practical choice for step-up diameter boring tasks.

This drill bit is suited for use in residential and light commercial applications where a 1-1/4 inch hole is required. The reduced 1/2 inch shank allows the bit to be used in standard 1/2 inch chuck equipment without requiring a larger dedicated drill press spindle. Typical applications include drilling through sheet metal, wood framing, conduit knockout work, and similar trade tasks. It is imported and sold individually.

Installation Notes

This bit is installed by a qualified tradesperson into a 1/2 inch keyed or keyless drill chuck. Secure the shank fully into the chuck before operation and verify the chuck is tightened properly to prevent slippage. Use appropriate cutting fluid when drilling through metal to extend bit life and reduce heat buildup. Always wear proper eye protection and secure the workpiece before drilling.
