DeWalt Impact Ready Bi-Metal Hole Saw 7/8" (22mm) - D180014IR

Double-tooth design strengthens each tooth for longer life and improved durability. Sharper Tooth Geometry cuts material faster for faster drilling. Thick, hardened backing plates prevent thread stripping. Deep-cut-style holes saws will cut 2x material in 1 pass. Increased high-speed steel height (highest in the industry) improves hole saw durability.
