So when I built my garage I needed to tool up since a lot of the tools in the old shop were my dad's..... I've got a handful of cheap die grinders from Harbor Freight that one by one quit working... literally brand new! The 90 die grinders constantly back off the nut that hold the gears in mesh so I got them adjusted and peened the aluminum into the nut next thing you know the gear is gone. After loosing all but one of the straight die grinders I opened a couple up, they used little balls sitting in a pocket with no visible way of retaining them in place to hold the bearing ends in the correct position??? I hold everything inline and reassemble and whataya know it works fine! So I guess I'll have to take all of them apart, drill the ball pocket through and drive in roll pins! What kind of junk is this!
