Set with impact wrench, pneumatic series 231, thanks to its durable construction, is an excellent addition to any automotive workshop. The INGERSOLL-RAND pneumatic impact wrench is designed for screwing and unscrewing threaded fasteners, including those that are heavily seized and have not been loosened for a long time. It features a shank with a 1” square cross-section end, equipped with a ball mechanism that allows for quick attachment of subsequent sockets. The ergonomic, warm handle cover increases operator comfort. An ergonomic switch allows for changing the rotation direction with one finger. The Twin Hammer mechanism is responsible for the high value of the precisely adjustable torque, controlled by a 5-position switch. The maximum torque is achieved within the first rotor revolutions, as both hammers of the impact mechanism can simultaneously strike from both sides. Sockets made of high-quality steel have a precisely calibrated socket, allowing even heavily seized bolts and nuts to be unscrewed without the risk of damaging their surface. Technical data: • Shank size: 1/2” • Maximum torque (reverse): 610 Nm • Working torque: 34-475 Nm • Rotational speed: 8000 rpm • Number of impacts per minute: 1200 • Noise level: 91.5 dB • Air consumption: 118 l/min • Air connection: 1/4” • Length: 185 mm • Wrench weight: 2.63 kg • Offered in a case set with 10 sockets: 10, 11, 12, 13, 14, 17, 19, 21, 22, 24 mm.
