Drilling a 33mm hole in a kitchen work top – How?
A 33mm hole saw or:
drill a series of small holes inside a 32mm scribed circle and finish it with a file or a rotary burr or:
Scribe a circle, drill a hole, cut around the circle with a jig saw with lots of to and froing to stop the saw jamming or breaking on such a tight circle.Posted 6 years ago
Happy to buy the bit. just couldn’t find one on line. All the hole cutters seemed to be for tiles.
The only wood one I found was at Screwfix for £20Posted 6 years agoTraceySubscriber
Dont know if they had the size you need but Aldi were selling them on SundayPosted 6 years agonoshkiSubscriber
A flat wood bit will do the job perfectly fine and should only cost a couple of quid, as has been pointed out a hole saw would not be deep enough to cut through, you would have to stop, remove some of the core then continue. A flat wood bit will remove the waste as it cuts. a small pilot for the bit to sit in as you start to drill will help.Posted 6 years ago
How do I drill a 33mm hole through my kitchen work top to accept the air switch button for the waste disposal?
It needs to be neat and work with a standard drill.
I am guessing I start with a small pilot hole but what will get up to 33mm without wrecking the worktop?Posted 6 years agoroddi18Member

You probably won’t find a 33mm flat bit but you will definitely find a 32mm one in most builders merchants as they are used for drilling a hole for a ‘Yale’ lock in doors.
32mm will probably do as i can’t imagine the 33mm is a dead tight fit as they usually allow a bit of tolleranceHeather BashMember
Or you can just buy one tool that will do a whole range of hole sizes for future use:Posted 6 years ago
