Product description:
The DeWalt DCG 405 is an 18-volt cordless angle grinder with a 125 mm diameter and a brushless motor. Thanks to the innovative brushless motor, it delivers higher performance with longer runtime per battery charge, more compact dimensions, reduced weight, and generally increased machine lifespan. The epoxy resin-coated windings further protect the motor from abrasive dust particles. At the same time, the optimized ventilation system inside the grinder ensures perfectly adjusted cooling for the machine and electronics, which also contributes to a longer lifespan. This is DeWalt's own Perform & Protect.
