Typically all I use this drill for is to install 1/2" bolts through our post to truss connection or post to bracket connections. Most drill will suffice for the application. However, large hole saws.....will kill most drills. Not the Flex volt from Dewalt. This test never even phased it. At the end you can see the Milwaukee Super Hawg has no issues Either, and if you are in the market for a new drill, I can promise neither of these drills will disappoint. I'd go with which ever works into your battery lineup.
