Hello all , my quest to find a good cordless SDS Rotary Hammer drill has lead me to this site and its my hope that one of you might be able to point me in the right direction . I am a plumber and I will often need to drill concrete ceilings to hang my pipe , these holes are usually 1/2 wide by 1 1/4 ' deep , I will need to drill between 10 and 20 holes to get started . These holes will in turn hold my shots to hang 3/8 threaded rod that I use to support my pipe or tanks . I have been looking at a few cordless rotary hammer drills and today I almost bought the Makita BHR241 http://www.makita.ca/index.php?event=to ... 30&catid=2 but decided ageist it because the sales man really had no idea just what this drill was capable of producing . I know that there are a few cordless drills out there in the 24 and 28 volt range that work great but , I was wondering if there might be something in 18 volt range that would meet the needs that I have for this particular tool . Thanks for any info that you may offer
