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 Justin Wallace

The brick wall had 1/8 inch thick solid wires running between the cement but the drill bit had no issues cutting through. Used the drill bit dry. I ordered with the pilot bit which made the start of the drilling process a little easier but I did remove the pilot bit after I drilled in a few inches. Made two 2.5 inch holes for 2 ductless AC/heater units. The SDS plugs arbor attachment worked as expected.Great value for the price. Not sure how many more times I can use the drill bit before it gets dull, but for the price and value, I am extremely happy with the purchase. 👍🏻👍🏻
