Query: Efficient for Drilling Small Holes in Concrete

This Makita rotary hammer is very efficient for drilling small holes into hardened concrete. In my profession, I am constantly required to set anchors in concrete. My rotary hammer makes the job easier than it would be with a regular hammer drill. It drills holes much faster than my old hammer drill used to do. And with less noise and vibration.I bought mine here at Amazon. It came with SDS bits and a grinder. I highly recommend this tool to anyone who drills lots of holes in concrete.
