Hole Saw, 3"

Cut through steel, tin, aluminum, fiberglass, wood and plastic Deep 1-5/8" (41.3 mm) cutting depth allows for cutting through 2" x 4" 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 backplate minimizes vibration for smoother, easier, less-tiring cutting Made in USA
