I bought this drill to drill holes in my lawn to aerate small areas. This was the only tool I could find for this application. (All lawn "core bits" are filled with core.) I was amazed that this bit continued to work in the mud. Even after heavy use, it hasn't lost its ability to dig through tough dirt. The advantage of this use is that the core is not pulled out, but rather the shredded debris is pulled out of the hole, making it easier to reincorporate the pulled-out soil into the turf.
