20V Brushless Motor Impact Drill WX373 with Lithium Ion Technology (No Memory Effect); including 2 x 20V / 2000mAh Powershare battery and quick charger. Brushless Worx Motors – The Technology of the Pros! Enjoy the advantages over conventional cordless tools: Up to 25% more power. Up to 50% longer working hours. Up to 10x longer life. Brush motors have two carbon blocks (brushes) that transfer electricity from the battery to the motor. Friction on the commutator generates heat and thus unused energy. Brushless motors deliver electricity directly with the help of a built-in computer. This creates no friction and no energy is lost – working time, engine runtime and power increase significantly. In homes around the world, more and more craftsmen are swapping their old tools for the new generation of power tools. Regardless of whether you are a professional craftsman or a home improvement worker – you want to work with high quality power tools! Tools that provide solutions. Tools that improve productivity. Tools designed for everyday use in extreme situations. Worx offers a high standard of quality coupled with innovation and modern technologies for enthusiasts and discerning homeowners.
