The Power Action BRS20 is powered by a brushless motor and it runs with a high no-load speed from 0-2000min. The saw also can be equipped with a 20V lithium-ion battery and a fast charger. The lock-off button prevents any accidental use and maximises safety.   There is no need for any auxiliary tool, just turn the chuck counterclockwise and you can insert the blade. The rubber grip provides a more comfortable grip experience.
