What are you talking about? You claimed the plastic gears were used as a failsafe. That's not true, higher quality equipment uses metal gears. Drills already have fuses and overload detectors built in.
Go watch some teardowns of cheap stuff vs expensive stuff and stop being a jerk.
I'm not your mom. I'm not gonna explain everything AND shop for you.
Too long to read. Some gears are nylon, yes, which is strong. I didn't get juvenile. I told you to watch teardowns. I don't keep a back catalog of every device with metal gearboxes, sorry.
Also! Way to completely flip the responsibility to on me. Very un-juvenile of you! I wasn't addressing "what tool should I buy", I was addressing "plastic gears are there to protect my drill/impact".
The shopping aspect was uninteresting to me to begin with and was not what I was joining the discussion for. :)
You can try to watch teardowns, like this DeWalt by Ave: https://www.youtube.com/watch?v=NHCS7JXfuv0
