Commonly called a ‘Nut Runner’, the Wolf ½" square drive reversible ratchet is so handy when a series of nuts need spinning down or spinning off a stud. Can be used with most 1/2" square drive sockets. Rotational speed 160rpm, and max tightening torque 60ft/lbs. The average air consumption is 4CFM at 90psi. Fitted with a ¼" BSP air inlet and supplied with a Uni Q/R adaptor. Please make sure that you regularly lubricate your air tool through the air inlet by adding a few drops of air-line lubricating oil before every use or by the use of an air-line lubricator.
