Twin hammer impact wrench

Powerful (twin hammer) and lightweight (plastic body) impact

Twin hammer impact mechanism

An impact wrench that combines the power (torque) of a single hammer with the tightening speed of a two-hammer. The two ring-shaped hammers strike the anvil in a balanced manner, achieving stable, high-impact force and excellent durability.

Lightweight composite body

The motor case is made of resin, making it lighter and easier to work with.

Reverse lever with integrated regulator

Equipped with a built-in regulator that switches between three forward rotations (right tightening side) and two reverse rotations (left loosening side). (YW-230PTH has one reverse rotation.)
