At first glance, the two Milwaukee cordless hand-held vacuum models look like tool boxes: they're about 18 inches long, 11 inches tall, 8 inches wide, and have folding handles on top. They are basically identical units but in 18- and 28-volt versions.
I had the opportunity to try out the Hilti TE 7-C and the Milwaukee 5363-21 rotary hammers while working on an addition to my own home. For this fairly average addition, my crew and I found ourselves reaching for these tools a lot more than I had expected we would. We used the tools to punch a large hole in my existing foundation for a 3-inch sewer line to pass through, to drill at least 30 holes for dowels into the existing foundation to tie into the new slab, to demo old concrete front steps (drilling a few dozen 1-inch holes to fill with a highly expansive agent for breaking up concrete), and, in hammer-only mode, to strip form boards and break up stucco.
