The DeWalt 12 Piece Reversible Ratcheting Wrench Set (DWMT19232) offers a variety of wrenches for any user need. 72 tooth 15 degree open end wrenches provide 5 degree arc swing and increased range in tight spaces. The full polish chrome set features stamped markings on both sides of the handle for easy size identification. Stamped markings offer permanent visibility and prevent wear. The stamped hashmark pattern on the handles provides additional grip points. These sockets feature DeWalt DirectTorque technology that allows greater contact with the flat surface areas of fasteners creating greater torque and prevents rounding of fasteners. This technology is particularly useful on already worn and rounded fasteners.
