These larger carbide core bits also come in two types with a pilot drill bit and a guide pin/plate version. Our personal preference is the guide pin/plate set up because weâve gotten the remaining cut concrete jammed in the bit a few to many times.ith the dry diamond core bit (up to 6â) in this setup the bit grinds the concrete, not pounding it like a hammer drill so the holes will actually be much cleaner with less chance of blowout on the backside.
