RED ROOSTER, Impact Wrench. With a composite housing and an excellent power to weight ratio, the RRI-1400M is designed for assembly and disassembly applications. The revolutionary impact mechanism, MECHONEER, provides a high level of energy per blow, combining the impact resistance of a Twin Hammer with the durability advantage of a Closed Hammer mechanism. It is fully lubricated with encapsulated grease, resulting in low vibration levels and low sound pressure. The tightening torque is adjustable in two positions with a release torque of 1,200 Nm. Ergonomic design, well balanced and compact. Easy to operate one-hand forward/reverse control at the trigger, with return air release through the handle. Download product sheet
