Bosch GDS18V-450H 18V bezuhlíkový akumulátorový rázový uťahovák 1/2 palca (samostatné náradie)

In a busy automotive workshop, a technician reaches for the Bosch GDS18V-450H to remove a stubborn, rusted axle nut. With a squeeze of the trigger, the brushless motor delivers 450 Nm of tightening torque and up to 800 Nm of breakaway torque, loosening the fastener in seconds without drama. This cordless impact wrench brings professional-grade power to tire changes, assembly work, and heavy machinery maintenance, all without the constraints of a cord.
