DeWalt DWE 4257

Motor with a very high copper content for stronger performance. The epoxy resin-coated winding increases the motor's lifespan. A special Jetstream cooling air guide effectively protects the motor from abrasive dust particles. Speed pre-selection via a knurled wheel allows for material-appropriate work. Overload protection prevents the motor from burning out by shutting off during overload operation. Tool-free change of the tool accessory through a quick-clamping flange. Tool-free quick adjustment of protective covers. Specially insulated carbon brush holders prevent the formation of short-circuit bridges. Self-shutting carbon brushes for longer motor life. Electronic clutch for increased user safety. A zero-voltage switch prevents unintentional starting of the machine after a power failure. Constant speed maintenance ensures consistent speeds even under load.
