The HC Pneumatic angle screw drivers of the SW55/...A series have a 90° head, valve lever and shut-off clutch. They are ideal for tightening work in confined areas, difficult to access and feature high torque values from 18 to 60 Nm, 300 to 400 min-1 rotation speed and ±5% shut-off accuracy, with high torque repeatability. These tools operate with unlubricated air delivery and are easy to handle, as they reduce torque reaction on the operator.
