Bosch + Concrete = No Brainer, great tool here, solid quality just wish they upped their warranty

I tend to agree with you this is the best heavy duty rotary hammer drill out there. I no longer even carry my Bosch corded rotary drill in van anymore as this drill will do a whole day of drilling large diameter holes up to 25mm and chiseling all day installing sockets in masonry walls, only to surprise me at the end of the day when I check battery level its still on 1-2 bars with another battery spare
