Holesaw variable pitch bi-metal 1-1/8"

Variable pitch holesaw. 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 bi-metal blade we use the highest grade of tool steel to outlast competitor's 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.
