Holesaw bi-metal 5-1/2"

Cut through steel, tin, aluminium, fibreglass, wood and plastic. Deep 1-5/8 inch cutting depth allows for cutting through 2 x 4 inch wood studs. Extra-tough M42 alloy blade, we use the highest grade of tool steel to outlast competitors blades. Steam oxide finish, no paint to gum up and slow cutting... The saw runs cooler for longer life and better performance. Extra-thick back plate minimizes vibration for smoother, easier, less tiring cutting.
