How to Replace the Switch on a Milwaukee Hole Hawg Angle Drill

The switch allows you to turn your tool on and off, as well as change the direction of rotation. Over time, the switch will wear. Eventually, it might no longer turn the tool on and off, or it may only work sporadically. The reverse switch can also fail, preventing you from changing direction.
