How to Completely Clean and Lubricate a Drill

The main danger to an electric drill is dust trapped inside the housing. It jams the anchor, button, speed controller, etc. Therefore, after each very dusty job, the tool should be disassembled, cleaned and lubricated. If you don’t do this, the drill will start to heat up and will not last long. Tool maintenance is a very simple matter that you don’t need to be afraid of.
