The YOUWE 21V Dual Action Polisher is the perfect tool for giving your car a shiny finish, removing scratches, waxing, polishing and restoring shine. It is a compact, lightweight and user-friendly tool suitable for beginners and professionals alike. Dual Action Polishers are perfect for improving the look and feel of your car’s paint without much risk. They work in two different ways: one, rotating in a circular motion, and two, moving in a random orbital pattern. This special motion, coupled with a highly efficient motor capable of reaching speeds of 5000 rpm, helps ensure eddy current-free and uniform surfaces while polishing. Compared to traditional rotary polishers, the YOUWE 21V Dual Action Polisher generates less heat, and the soft grip handle increases comfort and reduces vibration.
