Drilled through brick and concrete cinderblock exterior wall with ease

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. 👍🏻👍🏻

Pros

The bit bored fine, problem was the pilot bit kept falling out or the adapter.

Cons

Too heavy to use for extended periods of time

I could have cut through the cider block faster with a butter knife. After 25 minutes of trying to use this hole saw I threw it as far as I could, used my hammer drill with a 3/8 bit and drilled holes in a circle, took a hammer and chisel and knocked it out. Took way less time than trying to use this Chinese piece of junk.
