Well, we broke multiple teeth on 32P brass spur gears we were using. They all mated fine but they just weren't suited for the job. Unfortunately brass was the only material we could get the the gears in that would fit our needs. Never broken a gear in the bosch drill tranny - remarkable. We have had major clutch slippage and have broken the green drill case and the white tranny case. We lock it in gear with a zip tie pulling the shifting lever but at high rpm it sounds like it wants to shift out of gear.
