hi all,any feedback on these x cores? i use montolit core cutters for my grinder usually and they are needing replaced,,due to current climate im looking for something slightly cheaper and wondered if the x cores do what they say on the tin....100 holes per unit?

I have 2 X-cores and i find them quite good..

It's apparently going to be called a GTR 30 or something now, and it'll go under their general BOSCH brand and not RotoZip. Never used one personally but Dave has.

thanks guys

I find the x cores very quick dont know if they will do the 100 holes but they are quick and cleaner then wet drilling although a tad dusty. I have done alot of holes threw porcs and they were wearing very well I give them the thumbs up. but havent used any other dry cutter to compare them too..
