Ironworker here. We use a paste wax type cutting medium that stays on and makes a smaller mess. My tube is so old that I cannot read the brand anymore. We recommend a hex shank drive so we can use our impact wrenches. They make a world of difference.
My Bosch worm drive with mag base is definitely a higher quality saw. I own 4 worm drives and it's the best. My skillsaws and craftsman are also good saws. It's kind of hard to not like a worm drive when doing hard repetitive cuts such as beveling 2x4's by 16 feet at 30 degrees for concrete...
