Which Drill Bit should i use

[arrapeepz]

Im fitting a new bathroom sink and i have two( i think they are 10mm) white raw plugs to fit first thing is, This is where i feel stupid,which masonary drill bit should i use, 10mm or 12mm the reason for the confusion is the raw plugs look slightly bigger than the 10mm bit i have.
Can anyone suggest a solution.

10mm. You can open a hole out - making it smaller is a bit more difficult..........

10mm.
Then lightly tap the plug into the hole.
If the hole is too big the plug will turn when you try to screw into it.

I wonder if they're like some plugs that I have, which are marked as requiring an 11mm drill bit, which AFAIK doesn't exist.

As Scrit said (first) just use a 10mm drill and wiggle it a bit.

I spoke to a plumber at work and as i thought and u guys thought aswell, use the 10mm bit and wiggle it about a bit ( thats the technical term....Lol).
Well here goes.... Thanks guys

if you do "oversize"the hole by design or mistake cut a plug lengthways into quarters and push a quarter [or half dependant on the oversize]to the side off the plug as you push it in
if its into a plug already fitted and the screw wont tighten behind a batton for example
just push the quarter plug in through the hole in the batton

somtimes you get the feel and you know the hole is way to big just take a plug without a shoulder knock it through the batton into the centre of the other plug with the screw a turn into the plug

cut off any of the plug thats proud

even if the plug has only gone in a few mm but thats usualy enough to expand the plug so that it grips

or use a piece of wood plugged into the hole and dont worry about the rawl plug
