Rated 3 out of 5 by from  Erbauer Diamond Core Drill Bit  Bought this to put two vents in. It had to go through over a foot of poured concrete . It went through no problem and value for money but i did have two teeth break off. so im not sure how long it would last for .

Rated 5 out of 5 by from Diamond purchase.. Purchased in conjunction with the Erbauer Core Drill Accessory Set 5 Piece Set (required to attach the Core Bit to my drill). Used it to cut a hole in my external wall for a 100mm extractor fan duct. First time I've cut such a hole and this certainly did the job well. The depth was just enough for me to begin from inside then using a pilot hole complete the cut from outside in. Gives a nice even hole, Very pleased with the results.

Rated 5 out of 5 by from Great core bit. Bought to run ventilating ducting through cavity wall. Used it with an old sds plus drill and it easily cut through the concrete block and brick skin, leaving a clean finish. Only used it the once so far but no reason to suspect a different performance next time.

Rated 5 out of 5 by from Better than expected It was a silly thing to do: to read the reviews after I had placed my order - and fortunate, because I probably wouldn't have bought the part if I had. I needed the bit to drill 3 holes through a wall of block-on-flat (220mm concrete block), plus 150mm Foamglass insulation. The insulation was very soft, but it made the drilling more awkward. After reading some of the reviews I had serious doubts that it was going to happen. Well, going first gear with a heavy duty rotary drill and clearing the dust out of the hole with a hoover several times after drilling about an Inch, it took about about one hour to get through (each hole)... but it did: 3 times and is still in good condition! Maybe the trick is clearing dust and taking your time with gentle pressure on the drill. Just make sure you do have the side handle of the drill mounted, you will need it.
