Been eyeballing various 18v tool sets for a long while. Got turned off to the entry level stuff when borrowing a friends ryobi 18v angle drill to prep a stripped exhaust manifold bolt hole for a helicoil in an aluminum cylinder head. There was a lot of wobble in the mechanism to the point that it seemed very poorly made. Been borrowing another friends Milwaukee M18 tools (PRC made, non-Fuel models) and they're real nice, apparently he returned several cheaper makitas before biting the bullet and picking up a milwaukee combo set. Anyways I've been looking to start my cordless tool collection off with a high quality hex impact driver for use in basic DIY construction odd jobs for family and friends in addition to lightweight automotive use such as engine disassembly where the 1/2" corded milwaukee impact I've been using is overkill/clunky. Right now I'm looking at picking up the Milwaukee Fuel 1/4" hex impact driver kit with the XC batteries http://www.milwaukeetool.com/power-tools/cordless/2653-22. At $232 shipped this seems to beat anything from competitive brands, not sure if I should hold out for a promotion to try and get a better deal though. I'm also wondering if the XC batteries are overkill and will make the tool too clunky. Anyone using this impact driver have feedback? Is it worth the $$$?
