Are 36 VDC cordless tools really worth it? Few, if any, power tools are as important to installers as their cordless drills, with most using 18 VDC or maybe 19.2 or ~20 VDC for 'commercial grades'.
I noticed DeWalt sells a family of 36 volt tools, and sure enough they are pricey!
At ~$500 each, one could load up on 4 or 5 18 volt models.
For most security installer uses like drilling holes in studs, walls, metal jboxes and driving screws, the 18 V seems fine. Is 36 volt stuff overkill, or is it really better?
