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 Jeff Olson

Revainrating 5 out of 5

Works for concrete.

Drilled a 2 1/4” hole through 9” of concrete, not block and stumbled upon 5/8” rebar. I used 2 drills because they were getting hot. I put the drill in hammer mode, it seemed to cut better. High speed worked best. Took 2 good batteries and about 20 minutes. Bad ass bit. You can do it.

Pros
  • Easy to use
Cons
  • The diamond core may become dull over time with frequent use
