FORE Â Â 12 #1 Posted August 30, 2008 About 12-14 months ago a guy called Chris drilled a hole in an outside wall for me to accommodate an extractor fan. Â Unfortunately I've lost his number so I need him or someone else again. Â Seem to remember it was his missus who read my plea last year & suggested him. Â Anyone know what sized holes are required for a cooker hood with extractor? I'm thinking of just putting in an extractor this year and hopefully fitting a hood (with same hole) next year when we re-vamp the kitchen. Â Cheers!

vidster   10 #2 Posted August 31, 2008 Most extractor holes are stitch drilled from what i have seen over the last couple of years. Just measure the diameter of the extractor pipe. Stitch drill trough the wall using a 10mm coaxial drill bit and chip out the hole with a hammer and bolster.  If you want one perfect circle drilling it will probably cost you a fortune.

FORE   12 #3 Posted August 31, 2008 Thanks Vidster, but the last one cost me £20. I think he had a diamond tipped drill.  I'm hoping for a good one as i have a coating (tyrolean?) on the outside. Share this post Link to post Share on other sites Share this content via...
jl-heating   10 #4 Posted August 31, 2008 most trade people have a core drill in there kit, plumbers and electricians and the price of the kit has dropped considerably so usually quite competitive. i would think 50/60 would be a more realistic price for a hole to be drilled if its a second floor room you need it drilling into there are ladders needed etc. if you did stitch drill it the cowl to the extractor would cover it anyway but a core would be a better option. the last new house i worked on the electrician charged 100 a hole which i thought was a little excessive so there is a difference in cost depending who you ask. depending on the bricks in can be easy or very hard.  i drilled a hole for a forum member last year and it took 2 hours and no i am not exaggerating.it was 4 bricks thick and no cavity.

A core drill suitable for the job is £50+ What people dont factor in is tool wear. Core drills will only do a finite amount of holes before needing replacement.

FORE Â Â 12 #6 Posted August 31, 2008 This is ground floor, 2 bricks thick, with no (or an apology of) a cavity. Â I take your point that drills only last so long, but unless I find a willing contact I may buy one myself. Â Any of you know what size is required for a cooker hood?

ricgem2002 Â Â 11 #7 Posted August 31, 2008 hole for extractors usually 4 in (100 mill) Share this post Link to post Share on other sites Share this content via...
jl-heating   10 #8 Posted August 31, 2008 100 mm core is 55 pound from screw fix. drill is maybe 200 i have a makita, adapter to fit to the drill is 14 pound. pilot drill is maybe 4.99 ish.  you can hire them from champion hire maybe 30 pound a day plus 150 deposit. check the extractor size before you buy a core as some are 5 and 6 inch depends on size of room and type of extractor used.

dan2802 Â Â 53 #9 Posted August 31, 2008 Post up what area you are in, your more lightly to find someone local to you rather than get someone to drive across town for such a small job.
