This was an ideal boring bit for installing 4 inch p.v.c. pipe in concrete and for going through block and brick walls, just make sure that it's not old brick cause it will definitely vibrate the mortar lose.
These are with out a doubt the best carbide masonry/concrete bits available at anywhere near the price. Last a long time even with abuse, and we bore a lot of holes. You won't go wrong purchasing these Bosch bits. I do wish they had a place you could send these back to in order to get them "reconditioned" (resharpened or replace misssing teeth). Note have never lost a tooth drilling, only by one of my guys dropping them or abusing them.
Bosch bits are great. The packaging from CPO left something to be desired. Bit was in it's factory box (tube) but put in a box for shipping. No extras to prevent it from moving inside. I was surprised the bit was still inside!
