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. Shut-Off tools are similar to the Torque Monitor tools but with the addition of an in-built solenoid valve to shut off the air supply to the motors once the low limit has been achieved. Because the tool is not relying on a set air pressure to achieve stall at a specific torque, air pressure can generally be kept higher than with stall tools and this results in greater speed. This is the ultimate PT52 and will appeal to production line customers seeking a self contained shut-off solution with no need for complicated and expensive external controllers.
