Looks very tidy. How much did you use?
The space is a little longer than it looks and was a few inches deep too, so ended up using most of the tonne that arrived.
Is that Cotswold Chippings you've used?
You got a blowtorch? Heat the nut then maybe try again.
107mm Core hole , oh how I loathe old bricks
When I fitted our extractor, I reduced it down to 50mm. Couldn't bring myself to cutting such a gigantic hole in the brickwork. Still works adequately.What did you use to drill that? An Sds or proper core drill?
I need to drill a 152mm hole for an extractor fan.

That's a nice neat hole -
I had to drill one yrs ago for boiler flue and used a big drill from work - It went in so far then stopped cutting and I was cussing and blinding for 30 min till I realised the core drill was only 3" deep and it was full of brick - cleaned it out and through in minutes.![]()

I put a 152mm coring hole in for our extractor fan. Ebauer 152mm coring bit - I have the pilot drill screw in bit and the extension too. Used an SDS drill - 780W Bosch 2Kg class. Used a long drill bit from inside -> out then followed that hole using the pilot bit from the outside in. The coring bit doesn't skip when the pilot has a hole to follow.
A standard drill works -- just leave it doing it's on work, then every so often extract and continue. Also with a SDS drill give it a 15 minute break to let it cool (and the gearbox) half way through. Once through the brick, the block is easy and the sides of the brick hole acts as a guide.
