Impact Wrenches (One-Hammer)


One-hand impact wrenches deliver one impact per revolution and have high power output for their mass and size, making them ideal for automobile maintenance, demolition work, and construction machinery maintenance, which require a lot of loosening work. They are long-lasting, high-power one-hand impact wrenches that are particularly effective when removing and installing tires. In addition, the NW-1200B and NW-1600HA are environmentally friendly, low-noise, rear-exhaust type one-hand impact wrenches with rubber grips for ease of use.
