From the survey I'm guessing that you angling for a multi tool approach in which case you will have a hard time beating my torx oscillating multi tool! Best of luck with the project and whilst it's not ultra modern etc, the best power tool I ever used was an old bosch drill that my grandad owned. Sure it only had a 10mm chuck on it but it had a metal body and that thing would run forever. Scrap the plastic and make an all metal tool
