They're best only for punching holes in hollow-core concrete blocks -- unfilled with mortar and rebar. Their best feature is the overall length of the bit. But plugs can get wedged inside them as they have blind hole construction. Also, carbide cutting tips pale in comparison to diamond core bits. These have their place.

I always wondered how much of the tool's effort got frittered away in joint play, between the shank and the bit. Judging by how firmly wedged that joint got, I assume not very much! But beating the crap out of the bit to free the shank so it could be used with a different bit was a ritual I didn't look forward to. Of course, buying a second shank would've been the obvious answer, and the total cost probably would've been similar to a set of one-piece bits, too. Come to think of it, storing disassembled bits and shanks probably takes less room than the one-piece style, so I'm gonna say these are ideal only in situations where the tool spends more time out of its case than tucked away. Of course, the one-piece bits could turn out cheaper than the mix-and-match style, so perhaps they'll be attractive to the casual market too. Wait and see! More efficient, you say?
