HOLESAW,VARIABLE PITCH (4-1/8)
Greenlee's Bi-Metal hole saws cut through steel, tin, aluminum, fiberglass, wood and plastic. Deep 1-5/8-Inch (41.3 mm) cutting depth allows for cutting through 2-Inch by 4-Inch wood studs. Extra-tough bi-metal blade, we use the highest grade of tool steel to outlast competitor's blades. That beats premature saw replacement and saves you money. 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. Can be used with Greenlee standard and quick change arbors. Made in USA.
