M7 air impact wrench details
M7 3/8" Air Impact Wrench With 80-120 Ft-Lb Torque and Split Ring (NC-3831)
The M7 NC-3831 3/8” pneumatic impact wrench has a torque range of 80-120 ft-lb. This makes it ideal for handling smaller fasteners that don’t require high-torque applications. At just 2.9 lb, this air impact wrench has a comfortable, lightweight feel that lets you work a long time before grip fatigue sets in. Its comfortable pistol grip easily fits into most hands.
A twin dog clutch helps drive the NC-3831. This mechanism couples two rotating shafts that use interlocking teeth, aka “dogs.” With one pushing the other, these shafts rotate at the same speed without slipping. This prevents the twin dog clutch from wearing the way that friction clutches do. This quality has made twin dog clutches known for their strength and durability.
