We use a Metabo KHE96 and a Bosch both 2in SDS MAX I like both. the Bosch is a little shorter and compact the Metabo is taller I am 6'4 so I am more partial to the Metabo. Metabo makes outstanding equipment it is the most expensive but the quality is far Superior to others. I have gone thru several other SDS MAX drills and my Metabo is still kicken.
