The PT52 is engineered to be one of the lightest and fastest tools of its type on the market. The exceptionally compact 52mm diameter gearbox means that the tool is well balanced, light weight and provides excellent access to bolts. The integration of electronic torque measurement and control is achieved with the minimum impact on overall tool size and weight. Torque Monitor - these stall tools are fitted with a torque transducer, torque display and limit detection. As the tool is operated, the applied torque is displayed on the tool handle. It is possible to set low and high limits so that when the tool stalls, either an orange, green or red light is illuminated on the display panel.
