DeWalt Impact Ready 1-1/2" (38mm) Bi-Metal Hole Saw - D180024IR

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.
