The Greenlee 825-1 is a 1 In bi-metal hole saw built for multi-material performance on professional job sites, cutting cleanly through steel, tin, aluminium, fiberglass, wood, and plastic in a single tool. Its highest-grade tool steel bi-metal blade features a steam oxide finish for cooler, longer-lasting cutting, while the deep 1-5/8 In cut depth provides full clearance through standard 2×4 wood studs. The extra-thick backplate effectively minimises vibration, delivering smoother holes and reduced fatigue during high-volume electrical and construction work.
