EMERSON PROFESSIONAL TOOLS 825-2-5/8 Hole Saw 2-5/8 in 7/16 in Shank Bi-Metal

Cut through steel, tin, aluminum, fibreglass, 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 back plate minimizes vibration for smoother, easier, less tiring cutting. Made in USA.
