Rated 5 out of 5 by Great product A superb piece of kit and a great value for money. It made an easy job of cutting a 127mm hole through a double brick wall. I've used a Dewalt drill with a 750W power rating and a cutting speed of around 600rpm. Once your are through the first internal brick identify the centre of the hole on the 2nd brick by using the centre guide drill. Then drill a guide hole through this brick to the outside. Complete the job from outside using this guide hole. 18 Jun 2016
Rated 1 out of 5 by Diamonds are forever - again! I'd previously purchased the 152mm equivalent Erbauer bit to drill through a 110 year old solid 9" red common brick wall and it turned out to be rubbish as it took almost 5 hours 'solid' effort to get through the wall using my Titan SDS at full revs - without the hammer use, which shouldn't be required with any diamond cutting implement. In consequence a very negative review was left. As I also needed to cut a 125mm hole on the same wall for a boiler flu, so I gave an Erbauer127mm x 150mm diamond core drill bit an experimental 'chance'; in the hope that my previous experience was atypical. I can write now that both Erbauer core bit experiences were the same, the latter Erbauer managed to cut the inner 4" half of the wall before I gave up on it - after more than 3 hours of solid effort. I'll have to purchase another 127mm bit to finish the job... it wont be another Erbauer! 1 Jun 2016
Rated 5 out of 5 by great core /cutter needed this to install a boiler flue , cut through the wall quickly, no problems 15 Sep 2015
Rated 4 out of 5 by Unphased Currently being used to cut through a metre thick brick wall in a victorian railway yard. Hit against something hard, which it was troubled by. After ten minutes, i had made no progress. after inspecting the obstacle, it turned out to be a bit of old railway track which had been used as a lintel. This will have to be dealt with seperately. Point is, the the core drill was no damaged in any way. Cannot fault this. 3 May 2015

Hello Sumatra61,
The arbor you require for this core bit are for a SDS drill: DIAMOND CORE SDS PLUS ARBOR (27287) or for a standard chuck: DIAMOND CORE HEX ARBOR (34411). Hope that helps.
