Drill gearboxes?

Bosch is a great sponsor that has supported FIRST for a long time.

Interestingly enough, I happened to see a BOSCH drill transmission on a robot with a +4000 number. Made me smile and ask where they got it. Then we had to replace the BOSCH motor with a BAG motor to make it legal. Turns out this was actually a pretty simple swap.

For the OP:
You may want to check out 12V electric screw drivers. If they are 12V, they have a higher chance of having an easy to swap in FRC motor.
I believe that BOSCH makes a nice unit that 550 motor fit into, but be careful pressing the pinion as I think they are powdered metal and easy to crack. Milwaukee has a nice unit we used on 33 for the stinger back in 2012.

Electric screw drivers are easy to use a 1/4" driver to 3/8" or 1/2" socket to adapt to more "usual" FRC sized shafts.
