This might be slightly off-topic, but if you like this type of teardown content, I highly recommend checking out AVE's channel on Youtube [1]. He does plenty of tool teardown's, things like drills, all types of heavy industrial gear, and some electronics thrown in. I find is fascinating, because you start to learn about the manufacturing process, why mechanical engineers choose specific materials, how they cut corners, and generally how things are made at low cost and high volume.
Here's some highlights:
