The Tivoly Carbide 80mm Hole Saw is a precision cutting tool from Tivoly's carbide-tipped hole saw line, designed for drilling large-diameter holes in metal, composite, and hard materials via a drill press or handheld machine. Critical verification: confirm arbor compatibility separately, as this unit does not include an arbor—procurement must source the appropriate mounting adapter (typically 1/2" or 5/8" depending on machine type).
