5.0 out of 5 starsquality is actually pretty good
By T. Vikoren on October 29, 2015
Size: 4-1/2-Inch Verified Purchase
I know these are probably made in a large country about halfway around the world from where I live but the quality actually seems pretty good. I drilled though a 20 inch stone wall in PA with mostly granite and fieldstone with no visible wear of the bit. I had a steel dragon bit that self-destructed in the same material when the teeth debonded form the drill barrel. Do yourself a favor and get the bluerock drill instead of the steel dragon drill. The steel dragon drill is only one speed and doesn't have a safety clutch, when the tooth broke loose from my first diamond core drill the drill body spun around and nearly broke my arm.

5.0 out of 5 starsWorked Great
By Adamacorn on June 29, 2015
Size: 9-Inch Verified Purchase
Cored sixteen 9"inch holes through eight inch concrete with rebar, this bit worked like a champ. I think it worked better than a MK black bit I used last time.
