I own a Bosch GSR cordless screwdriver/drill. This drill automatically locks the spindle so that it can be used as a passive screwdriver, e.g. if the battery is empty (that's what the manual says).
Sometimes I use it to screw climbing holds to a climbing wall (using M10 threaded screws). However, even the drill setting on the slow gear doesn't provide enough torque to fully fix larger holds, so I currently use an allen wrench for the final (half) turn.
Can I use the cordless drill in "passive mode" for this final turn, or will I damage it? If so, would it be better to release the trigger and then turn the drill, or should I fully press the trigger while turning it?
I could imagine that the latter would lead to overheating, but this is only for a few seconds. But I guess the first option would probably lead to torque that is larger than the drill is designed for.
Additional info: On a climbing hold manufacturer's website, I read that the holds should be tightened with a torque between 35 and 45 Nm, while Bosch lists a maximum torque of 30 Nm for my drill.

You can but it would be easier and more efficient to bring a manual wrench. A wrench or ratchet will let you apply your torque closer to the same plane as the head of the bolt. Turning the drill will be like a ratchet with an extension on it. Use the right tool for the job, your tools, your watch, and your wallet will thank you for it!
