Eagle Cutting Tool 1090D-054-I Drill Bit 27/32 in

Product Description

The EAGLE CUTTING TOOL 1090D-054-I is a bright ground Dyno SD jobber-style drill bit sized at 27/32 inches with a 1/2-inch straight shank. Bright ground finish indicates a non-coated, precision-ground cutting edge suited for general-purpose drilling applications. The 1/2-inch shank makes it compatible with standard 1/2-inch chuck capacity drills and drill presses commonly found in machine shops, fabrication environments, and on job sites. This bit is an import-grade option intended for technicians and tradespeople who need a reliable large-diameter drill bit at a practical price point.

This drill bit is appropriate for use in metal fabrication, plumbing rough-in, HVAC ductwork layout, electrical conduit work, and general construction drilling. The 27/32-inch diameter is a common size for hole preparation ahead of tapping, reaming, or fitting pass-through hardware. It is used by plumbers, pipefitters, electricians, HVAC installers, and general contractors working in both residential and light commercial settings where oversized holes are required through metal, wood, or composite substrates.
