FAQ

What's the difference between twin hammer and pin-less?

    1.Twin hammer is mainly used in 1/2 “ air impact wrench, because the torsion produced by this structure is much greater than that produced by single hammer, and it has higher requirements for materials. If this structure is applied to the 1 inch impact gun, its striking block  is very easy to crack. 

  2. The main structure for 1 inch air impact wrench is single hammer and pin-less structure. This kind of structure is the most ideal structure at present in terms of resisting ability. 

    3.Principle of work is the compressed air output by the air compressor. When the compressed air enters the air cylinder, it drives the impeller inside to rotate to generate the rotating power. The impeller drives the connected striking parts to move like hammering. After each striking, load or remove the screws.
