Probably dumb bathtap drilling Q

Aug 25, 2004 4 Replies

So I have new Acrylic bath, new mixer tape for it with what I'm sure is 3/4BSP threaded tails. (To be connected to 22mm pipe)



And I need to drill holes in the bath to make it fit.



What size drill do I need? Or do I use a hole saw sort of thing? The chuck on my Bosch is only 13mm too...



All advice appreciated!

Err, big enough for the tail to fit through? 22-25mm I guess without measuring a fitting.

Hole saw is probably best, but I've drilled them ok with a spade type wood bit. Just don't go to fast.

Doesn't mater, the shafts of the drills etc. are sized small enough to fit.

28mm hole saw. You might get away with 26mm but you'll need to be very accurate with the hole centres. (180mm centre to centre IIRC).

Thanks for all the replies!
