That would work, but not for too many holes before it got dull beyond repair or it burned up, and it would be very dusty as well. Nothing worse than making a hugh dusty mess of a jobsite with concrete dust all the other contractors will hate you so much! And nothing worse than your boring tool going south in the middle of the day on a jobsite becuase you burnt it up doing 200 holes. Imagine breathing all that dust or having to keep a pocket full of masks, a head covering and googles. Than you have to keep cleaning those off and /or live the rest of the day with all that dust in your hair, inside your shirt and shorts.
An elderly and experienced contractor taught me to work smarter.
The key to a clean job and long concrete cutter life is flowing water with a small amount of a surfactant added to it. Doing that has made my concrete cutters last years with only a mild honing once in a while. Before I knew that "secret" I used to do holes like that and than I got tired of buying new bits/saws/bors all the time. IF you can't get the water everywhere you use a shop vac with sand tube barriers around the area. Than clean up with a floor squeegee. The job site foreman is always impressed with your professionalism and they recommend you on the next job they are on.

But, that just might be my mistaken impression based on the pics and text. Maybe this thing will core drill through magma to China and pop out of the OP's hole right after one of bis segments falls off and binds his drill good and tight, who knows?? Hahahhahahahaaaa
oh I see, I missed a quote. Whoops. Still though. Waiting for pics of that baby popping through a slab, I know you got 'em.

Gadgeteer, merely stated the bit drilling the masonry looked like the one he had made for the purpose of drilling holes in dirt to install sprinkler heads. He never made any claims about using his for hard materials. For that purpose, his bit could conceivably drill 100s if not 1000s of holes. Had he needed to drill through masonry or even hard rock he could have removed the carbide tips from a circular saw blade then brazed them to the teeth of his drill, kept his RPMs in check and with a flood of water done equally as good a job as a store-bought masonry core bit
Never try to tell me it can't be done
