(More efficient than a round head reaming tool, the drilling speed should not be too fast)It needs to be used with power tools such as hand electric drill, saving you time and improving work efficiency.The drill expander for molding tubes using heat by friction way more surface of between the flare and the Valve. Preserve copper malleability during the molding process, for a leak-tight fitting.Specification:Color: BlackSize: 1/4" 3/8" 1/2" 5/8" 3/4" 7/8"Shank type: Hex HandleHeight: 44.6mm/1.76 inches, 49.3mm/1.
