The EY-7443 Autogear Drill & Driver automatically delivers. The 7443 AUTOGEAR features an automatic gear selection mechanism which changes to suit the application automatically – economising time and power. By sensing that it requires more torque, the unit will change gear to accommodate and reduce load on motor. In extreme overload situations, this sensor will cut power to the motor to protect the tool. The clever ’Kick-back’ protection reduces potential injury to hand or wrist in case where bit or holesaw suddenly jams.
