If you need an abrasive chop saw to put to work everyday this one will make you happy.  Good power and table fence.  The quality is there and the smoothness of motion and power to drive through a cut is obvious once you use it.  Earthquakes are real in Japan and they do a lot of reinforced concrete as a result they have built tools to support their needs.  You won't go wrong with any of Makita's  metal grinding tools or hammer drills.  Just as smooth as Milwaukee with less weight and better than Bosch with less jiggy knobs.
