Kobalt Grinding Gears - But We Get It Repaired

Abusing the Kobalt 1/2" drill finally caused an issue. We have been running big hole saws and auger bits for years and something in the gearbox finally tweaked, and it got hung up between gears. Took it apart and was able to get it back working. This old drill has been thru lots to torture and it looks like it will have to go thru a lot more before it is finally done. Also show a quick view and discussion of my old Porter Cable drills. I liked them, but no sure they could have survived everything this drill has been thru.
