I’ve only thought about doing this myself but from what I remember you need either a dedicated core drill or an sds with a clutch so you don’t break your wrists if it grabs. Didn’t seem worth it to me at the time.

Why not hire one, along with a rig / stand?

This might be a silly question, but how hard is the brick? The combi would work on our house brick but maybe not yours. A friend has a stone built house and needed specialist equipment to do the job.

You must not use hammer with a core bit.

I need to core through our brick external wall to fit a couple of extractors.
I have a decent dewalt combi drill with a hammer function but am presuming it will be insufficient?
Presuming I need one of these (if so,which?):

and a 150mm bit for the hood - so presume this would be fine: https://www.screwfix.com/p/erbauer-diamond-core-drill-bit-152mm/68843
This is the hood:

Reviews I've read suggest getting the largest ducting to minimise the noise (which on this model appears to be 150mm, though another review on the NEFF site says 10" which would be 250mm - not sure how that works)
