I can fit (All Makita) half inch and quarter inch impact drivers, grinder, hammer drill, jigsaw, mini vacuum, multitool 6 batteries and charger along with sever small Milwaukee cases for the bit needed in my Packout main trolley box. I find the trick is to not have any of batteries on the tools. I have to keep the half inch drive sockets out as they are deep ones and the box is too big.
