Rated 4.8 out of 5 by 10 reviewers.
Rated 5 out of 5 by Drills concrete like butter. Wish I had it sooner! This was rated best for quality and performance, and I am glad I followed those recommendations. You barely lean into it to bore a straight and clean hole... no fuss, no overheating drill motor or bits. April 10, 2014
Rated 5 out of 5 by Excellent Hammer Drill Bought mine a few months ago and noticed that it must be an updated version because it's 9.2 Amps..............a real little powerhouse! With good quality, sharp bits, it will go into masonry & concrete at a very reasonable rate short of using a rotary hammer drill for more demanding jobs. One reviewer said that his depth gauge wouldn't hold, but if it's put in correctly with the teeth facing the right way in the slot, it works just fine. Great little brute-of-a expected from Bosch.

Rated 5 out of 5 by Great Tool I bought this tool a couple of weeks ago and everything seems to be up to Bosch standards which is very high. It has plenty of power and feels good in your hands. I really like having two drive speeds and the fact that this drill is not huge or overly heavy. It comes with a nice case also. September 30, 2013
Rated 4 out of 5 by Would have been 5 stars Read the other positive reviews to see what to like. The depth gauge is the only poor feature... it consistently slipped with just the slightest pressure and was useless. February 26, 2014
Rated 5 out of 5 by great product, built to last no plastic here Good Hammer drill and good straight drill. Service and shipping were very good just as promised February 11, 2014
