Rated 2 out of 5 by from Does not run true I’m putting the same revue on the Erbauer 117mm and 127mm diamond core drill bit items as they performed identically. I used them to drill through a cavity wall (concrete inner, very hard brick outer) using a brand new DeWalt diamond core drill, and an Erbauer arbour , with extension shaft for the exterior brick. The drill and arbour run perfectly true, but neither the 117mm nor 127mm core bits did! Unfortunately, due to time constraints I had to use them. They cut through both materials very well, the concrete blocks only taking a few of minutes, the brick about three times longer. The problem was the amount of vibration caused by the run out. The run out is such that it is obvious to me that Erbauer do not carry out quality control on each item; even a cursory test would show it, even at slow rotation speeds. It became tiring, and impossible to maintain precise control over the direction of the cut. Luckily, in my case that was not crucial. I’m only likely to use each bit a couple of times, so it’s no big deal to me. If I expected to have to cut similar holes regularly I’d scrap the Erbauer bits and buy a better quality brand as, besides the issues I’ve mentioned, I’m sure that it would lead to damage to the bearings in the drill. Disappointing as a correctly aligned jig when constructing the bits would solve the problem. Don't forget. I'm reviewing the ones I purchased. Others may have been luckier.

Rated 5 out of 5 by from Kitchen fitting Does a great job through Breeze block and brick. Obviously more hard going through brick but this unit handled the work load just fine.

Rated 3 out of 5 by from Erbauer 127mm diamond core bit Used recently on a 1st fix, cored through for a soil stack and boiler flue, effortless cutting power through block work and brick, used Makita 110v diamond core drill

Rated 5 out of 5 by from A really good boring time An excellent product made short work of drilling through a cavity wall to install a new toilet drain. I had bought an a diamond core extension but it was not needed as this drill went through both skins without the extension.

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.
