Kitchen Extractor Fan
Hi
I'm installing a new kitchen and I need to put a hole in the wall for the cooker hood fan outlet.
Any idea what size hole is required? - I would like to use a core drill bit to make light work of it.
Have i asked "how long is a piece of string question"......
Thanks

The most popular size is 125mm, check the outlet diameter on your hood. We sell several 125kits none over a tenner delivered. Other sizes available
to, have you bought your cooker hood yet ?

I just bash a big hole and cement in a section of 125mm drain pipe. Then a push on vent cover just slots in.

Core drill is a nice idea, but don't even think about using a normal drill. Ask me how I know. Go and hire (discovered mammoth hire is very
cheap online) or get a bloke with one to pop in for an hour.
Or these days I drill around the hole and then knock it through. Me being cheap and all.

127mm core drill does the job, as said above make sure you use either a dedicated core drill or a low speed sds with the clutch set to low.

I just use a screwfix SDS drill. Bloody heavy but does the job. Wasn't sure if it had a clutch untl I used a core drill for the first time.
Quickly found out it did when the bit caught- still have to hold on tight though. Def a job for a 125mm bit- unless the wall is wafer thing you
won't get a dead straight hole through the wall so you need a little "adjustment" room to be made up with some cement afterwards.

Modern walls are 11" so you need a long core drill
Do a small pilot and cause through from both sides

Most of the top end extractors are quite powerful and sometimes twin motors and generally use 6” or 150mm pipe, the daft thing is they also come with
an optional reducer that fits directly onto the extractor reducing the size down to 125mm which if you use makes the more powerful fan more noisy. So
bigger the pipe, less sharp bends should make it quieter in use.

Thanks guys.
Pilot hole is a good idea. It may take some drilling as the walls are old red brick.
Cheers
