Powerful 1/2″impact wrench for unscrewing wheels (up to size M28) with a power of 300 Nm . Tangential impact causes relaxation of threaded joints in baked bolts, tightened even to a torque exceeding 300 Nm. The wrench is equipped with a four-pole engine (4 brushes, instead of 2 ), which ensures higher speed under load, perfect for work in the workshop and on the construction site (tightening of handrails, barriers, formwork and long carpentry screws).
