Where do you come up with such nonsense? Based on what do you believe that the Harbor Freight will outperform a Bosch (assuming you are talking roto hammer and not some worthless hammer drill). Why because somebody on the internet drilled a few holes in concrete that was 40 years old. How demanding is that? How about chipping and breaking with that roto hammer. How about drilling a 5/8 hole 8 inches deep? How about whether the roto hammer can be repaired when it breaks or just tossed? How about the parts availability and longevity of the tool?
Is there a reason you feel a need to be so condescending? Yes we are talking roto hammer. The last time I was using it I was drilling 5/8s holes at HD of all places. That size hole was at the top capacity of Bosch drill I was using. It did the job but just barely. I went through several very expensive bits doing it. At the next HD the rep was nice enough to grab a bigger drill from the rental dept. It made the job much easier. How would the HF tool compare? Honestly I can only guess from the reviews of the people who actually used it and the fact that it is a higher capacity unit. It would be great to do a side by side comparison.
