For cutting holes for new low-voltage mounting brackets, should I just stick with my trusty keyhole saw or maybe start using my oscillating multi-tool? I love the multi-tool for cutting huge sections of drywall out since it's fast, precise, and cuts clean. However is there any downside to using one for cutting smaller holes like for the brackets? Any advantage to the keyhole saw? Maybe avoiding slicing through AC wiring too quickly? My only complaint about the keyhole saw is that it can cut kind of jaggedly depending on the rock. That or maybe I'm just not doing it right. Haha.
