Operating Principle of Kocu KC-3900 1/2 Inch Twin Hammer Impact Wrench:

The two hammers continuously generate extremely strong twisting impacts on the socket, allowing for quick tightening or loosening of bolts with high force while ensuring stability and durability. The twin hammer mechanism helps distribute impact force evenly, reducing vibrations and extending the equipment 's lifespan during continuous use.
