Grinders and polishers with built-in battery

Built-in battery

— sanders with a built-in battery are as compact as possible, but the batteries themselves cannot be quickly changed - so you will inevitably have to take breaks for charging during work. Therefore, this method of supply is typical for low-power instruments. In them, small size is more important than a long period of continuous operation, in addition, a low capacity allows you to achieve good autonomy even with small sizes (and, accordingly, capacity) of batteries.
