Rated 5 out of 5 by from Excellent Excellent drill bit. Cuts like butter through standard (dry) brick. Great price and usual excellent service at Screwfix Boston.

Rated 5 out of 5 by from Simply brilliant core Drilling: Reinforced concrete (aggregate based). I was very dubious this core would drill the above material. I even rang Mexco technical support (TS product) and they assured me it would simply burn out and I'd need to hire a professional core cutting machine. Based on another Screwfix review I thought I'd try this Erbauer core - it has drilled 3 holes each 350mm deep in the most difficult material you could imagine. I used water sprayed into the hole to help cutting and it really did help keep the cutter cool and maintained a diamond dressing on the cutting surfaces. I used 2mm of the 8mm (so 6mm left) on the tool after 1m of drilling. That's very impressive in my book. I took photos that showed the stones and rebar it machined away but can't upload here. I hope this review helps anyone that is not sure if it can cut through reinforced concrete... it can. Use caution with water (I was drilling down so no problems but obviously don't get anything electrical wet). Also use a good SDS machine (not on hammer). Excellent.

Rated 3 out of 5 by from No arbor included So I am waiting to use this item as no arbor was included, despite a previous review stating it was. Also you will notice the arbor size is not mentioned anywhere in the item description. This is one of those cases where the actual requirements for using the item was not considered in the item description unfortunately which has now held me up on a job.

Hello, can you recommend a pilot holder for this core?! Thanks.

Asked by: Klinton

Roughly how many times will this drill bit cut through brickwork before it's worn out and hard work to use?

Asked by: 506PI
Hi 506PI, Unfortunately we do not have the information regarding the average life of this corevdrill, as there are to many variables in how it is used and maintained. Thank you for using Q&A. PB
