The 2135QTi set the standard for performance with the best power to weight ratio on the market in its class. The new 2135QTiMAX raises the bar with 780 ft-lb (1054 Nm) still at only 3.95 lb (1.84 kg). The new design includes enhanced controls for even greater comfort and convenience. We’re so confident with the durability of this tool that we are backing it up with a 2 year warranty at no additional cost. The 2135QPTiMAX has the same quality features as the 2135QTiMAX but with a pin-type socket retainer for improved socket retention.
