Cheaper lower end copy tools for work amd can get the job done. But they normaly don't have a controler to monitor the battery amd tool. So melted wires like this can happen very easily. Theu are good if you are on a budget, but always be mindful of how much power they drawing from the batteries. #tools #toolsrestoration #copymakita #copytools #cheaptools #budgettools #knockoff #diy #repairs #powertool #toolrepair #deandohertygreaser #powertools #repair #makita #deandoherty
