This Ingersoll Rand DXSK2M15L 15-piece impact socket set features a proprietary DXS2 Drive system, designed for use with Ingersoll Rand DXS2 impact wrenches. The DXS Drive system utilizes a spline-type interface to deliver enhanced torque efficiency, reduce overall tool length, and provide a longer wear life compared to traditional square drive sockets. Constructed from impact-grade chrome-molybdenum (CR-MO) alloy steel with a manganese phosphate finish, these sockets offer resistance against corrosion. Each deep socket features a 6-point hex geometry with relieved corners to minimize fastener rounding and high-visibility laser-etched markings for easy size identification. Ball nose retention pins facilitate quick, tool-free installation and removal. The set includes deep metric hex sockets in sizes 12mm, 13mm, 14mm, 15mm, 16mm, 17mm, 18mm, 19mm, 21mm, 22mm, 24mm, 27mm, 30mm, 32mm, and 33mm. It complies with ASME B107.110 and comes organized in a foam shadowboard tray.
