M7 air impact wrench details
M7 3/8" Air Impact Wrench with Twin Dog Clutch and 1/2" Bolt Capacity (NC-3812B)
This M7 pneumatic impact wrench features a positive clutch mechanism. It connects two rotating shafts with interlocking teeth or “dogs.” This is why this clutch type is also called a “dog clutch” or “twin dog clutch.” These two clutch shafts push against each other and rotate at the same speed. This helps prevent slippage and reduces wear and tear. Positive clutches are not used to control the tool’s torque.
