Harbor Freight Bauer hammer drill project

We bought a Bauer 4 in 1 hammer drill to open up our crawl space entrance hole so that we can get our new furnace into the crawl space. We are trying to get that stuff out of the main house. The filter for the furnace will be up in one of the closets and in the pantry. It worked great but not at first but after I used it for a while it loosened up and did it's job!
