Drill bit help please

[Jonny ///M]

Hi there, looking to drill a 40mm hole for a push button flush on the toilet so my dad picked up a 40mm hole saw.

I notice we need something else so purchase http://www.diy.com/nav/fix/power-to...-Holesaw-Arbor-With-Drill-Bit-11-1mm-11407733 to hold the hole saw.

The arbor doesn't fit in the smaller sized head on our drill

I can't see an adapter on the B&Q site so can anyone point me in the right direction please?

You need a new drill with a 13mm chuck. Guess your using a cordless drill with a 10mm chuck?

Will a hole bit cut through ceramic?

There are some cheaper one on there too but for the price I'd just go for that one.

Hammer should work.

Yep, larger check and you should be good.

When using larger holesaw it's best to use a mains drill, I find cordless ones don't have enough torque.

No.

Do what I did, buy a cheap tile diamond blade from eBay, tile over then drill through the tile and the backing, tidy up and fit the push button.

Should cost <£10 each, I bought for every event, push button, rad pipes and shower head, all last a couple of holes before burning out and just making a mess but are a cheap solution without buying a whole set and holder.

It is a wired drill we're using but its a pretty old one as far as I can remember. Can't see that screwfix site for some reason, signal is crap in this hospital.

Its only a wooden panel we're drilling and it won't have tiles over it.


Next question...is it ok to trim a little off the inlet to the cistern? With the 90 degree elbow ifs sitting a little close to the side of the the unit for my liking and the inlet has room to spare.

You're drilling wood!

Then use a wood drill bit
