The drill has lasted me almost 10 years at this point of light usage. I opened it for the first time to re-grease with some lithium grease, and noticed despite it saying brushed motor it sure looks like I’d need a Dremel to open this. Figured I’d ask if anyone has seen similar and if so, is there a trick to opening this when the the brushes wear out?
It is a ryobi, at ten years and $40 when I bought it I probably can’t complain much on cost. When it breaks I’ll have to see if I can find a replacement motor or force it apart like you mentioned to see if I can get it to go again.

Looking on the motor looks like the right keyword was rs-775 . $20 for a new motor, I might still try to get the brushes out when the time comes just to see but that’s half the price of a new one.
