Cleco 55 Series Stall Non-Reversible Angle Nutrunners feature planetary gears designed for tool speed changes with minimal parts service and replacement. The heavy-duty spindle bearings and splined retractable spindles on the Cleco 55 Series Stall Non-Reversible Angle Nutrunners reduce friction, improves torque repeatability, and prolongs life. Cleco nutrunners are available with stall-type torque control, giving operators more control over power output and speed.
