Review on 9.5" Diamond Dry Core Bit For Brick And Block With SDS Plus Pilot Bit Adapter, 5/8"-11 Arbor And 9.5" Drilling Depth - Perfect For Concrete Drilling by Gary Hall

Revainrating 5 out of 5

Best thing since sliced bread

This cored through solid concrete and old blocks easily. One trick I forgot to do that would have made it even quicker -- once your coring is started, remove the pilot bit. It makes a clean hole relatively effortlessly.

Pros
  • One hole worked perfectly
Cons
  • May not work well on uneven surfaces
