The Greenlee 825-1-1/8 is a 1-1/8 In bi-metal hole saw engineered for multi-material cutting on demanding job sites, slicing through steel, tin, aluminium, fiberglass, wood, and plastic with equal reliability. Its extra-tough bi-metal blade — made from highest-grade tool steel with a steam oxide finish — runs cooler and longer between sharpenings, while the deep 1-5/8 In cut depth handles full 2×4 wood studs in a single pass. An extra-thick backplate minimises vibration for cleaner holes and reduced operator fatigue across high-volume electrical and construction applications.
