Cordless grinders and polishers

Battery

— this type of power makes the tool as autonomous as possible, allowing you to work even in the absence of sockets and easily move from place to place. In addition, the absence of a network cable is also a serious advantage. On the other hand, a cordless tool is noticeably more expensive and heavier than a “network” one similar in characteristics; the power of such grinders is relatively small — otherwise too bulky and expensive batteries would be required; and the battery life is limited, and after the depletion of the energy reserve, you have to take a long break to recharge the battery. So this option makes sense to consider only in cases where mobility and lack of wire are critical.
