whats a good bit size to use to put holes in tubs

Should I use a straight 1/4 in all tubs

Remember using drill bits it will be a long and the plastic might crack.

I recommend a soldering wand, if you use that make sure the area is well ventilated. It will give you the perfect size for any tubs.

If you really want to use drill bits 1/4 will work.

Definitely be careful about the tubs cracking. If you don't make the holes too big it should be fine. I soldered most of my holes, but since I got my dremel I've just been "drilling" the holes with it. I'm not sure how small the two drill things are, my best guess is 1/8th.

All done :) yah I have a set of really nice bits. I just needed the size to use :)

What did you end up using?

went with the 1/4 looks good.
