it’s indoors with carpetHave you tried flushing the hole with water?
I own a house with concrete walls they are evil and that's how i have had to do it, i normally use a 6.5mm SDS and do holes about 15mm apart all round the core hole, if it gets very silly i go upto 12mm in the 6.5mm holes, my mates uses a fairy liquid bottle with just water in and wet cuts it.Another suggestion & probably time consuming
Could you not drill several holes around the diameter of the hole your trying to drill?
Core drill should go through that no problem, it's the machine that's the problem, try 3ft damp sandstone with a void filled with crap, it grabs like buggery.

Some times its easier just to drill a circle of holes and just bash it out with hammer and chisel or a breaker.
Lidl have SDS drills from Sunday 2nd August.
This is not a recommendation just letting people know. And I'm not buying one.
Had to do similar in a bungalow lto two storey lift.try drilling 6 - 75mm holes through 12 inch x half inch steel rsj encased in solid concrete drill one side in the concrete with an sds drill then core it to the steel .then drill pilot though the steel 10mm then drill right through and out the other side . core concrete out to the inner steel then cut through the half inch steel with a holesaw and a load of cutting compound. 1 hour each hole to put a load of data cables through a building
I was suffering from tennis elbow at the time and they were overhead beams across the room under the ceiling had to stretch up and out with the heavy drillHad to do similar in a bungalow lto two storey lift.
Through 2x 2x9 then through the rsj then thought a further two 2x9 for cabling.
Boring day and arm cramp by home time.

I’ve seen them do that up town. What’s the point of the concrete when you’ve put that much steel in the ground anyway. “Engineers” I guess.We had a job doing that sort of thing in this building in the early '90's so they could put rebar through the foundations. The original building stood on layers of RSJ's in rows of a dozen or so and they wanted to cast the old bases in with the new (very, very heavily reinforced) slab. We spent months drilling holes through rows of RSJ's and really nasty concrete, then they water-jetted the concrete out from between the RSJ's and poured new concrete into the lot.
I never saw so much rebar in a slab. It was so dense you couldn't drop a spanner through it.
