drilling bath

[dubdad]

hi all
drilling tapholes in an acrylic bath

i was thinking of using a diamond - tipped holesaw-the type used for porcelain tiles- for drilling my new acrylic bath (mere with carronite reinforcing). is this ok?

i am buying some of these cheap from a chinese site for the porcelin tiles going in too (the circular type without the pilot bit) will use a guide too, an adjustable plate and sucker job with 4 bearings to hold the bit steady. so i figured it would b handy if i could use them on the bath as i dont have a decent holesaw with auger, and they are expensive from what i have seen.

i read somewhare a carbide steel bit is best with the teeth ground down to a shallower angle, so u are effectively grinding the acrylic, fine if you are doing this all the time.

if its ok to use should i drill fast or slow, and use some water for cooling, lubrication?

any pointers greatly accepted

£8.27 is'nt really going to break the bank is it?

It'll be cheaper than if you ruin your brand new bath.

Drill it on a nice slow speed.

Also use the pilot first then add the holesaw, if you try to do it all in one you may split the bath

I used the tools shown above and they drill the bath no problem at all. I signed up to this forum because I had a problem with a bath that was cracked. I had left the protection on and drilled the holes and when fitting removed the protection to reveal a crack and of course the suppliers wouldn't have it back once drilled , so a simple piece of advice is before you drill check absolutely everywhere.
