Used this bit through concrete, brick, reinforced concrete, asphalt. Probably used it 20 different projects so far. Still sharp enough that I'm not considering replacing it anytime soon

Good price, fast shipping and they last for quite a few holes. I will purchase again as this was the 10th different size bit I have from Bluerock

This core bit was used to drill 2 holes about 8 inches deep into poured concrete. After drilling the first 1 inch with the core bit, I then drilled 8 small relief holes around the circumference of the hole. The remaining 7 inches took about 5 minutes to complete. I used an 8 amp SDS Plus rotary hammer on Drill Only mode with a connection adapter (available on amazon for $12). The 2nd hole ran into rebar so add another 15 minutes to the drill time.
