Anyone ever done this? I am inserting one of those "Quickie Flush" heads at the high end of my very shallow but wide tank. I am planning on using a 1-1/8" 'spade' drill bit. I've read that rather slow rotation and light force should be used; let the plastic melt a bit from the friction… let the bit do the work. I believe this Valterra tank is made of that ABS black plastic. I'd rather not crack my tank…  any suggestions? Perhaps a hole saw bit would be preferred… Thanks! |

I suggest a hole saw. They are less likely to grab...

I suggest a hole saw. They are less likely to grab… Thanks Vikx… my research is showing a split decision on this. I think the key is the handling of the bit and the speed. Slow and steady, heat up and melt through the plastic. Also, some plastics are more prone to cracking. The tank plastics are fairly flexible. In making my battery box from a plastic storage container, I had to make 4 cuts through the sides to cut the bottom off. Used my table saw and was also undecided as to what blade to use to do it. A guy at the hardware store recommended a steel cutting saw! It's just a very hard, very gritty disk… no teeth at all. They're also quite cheap at less than $5 for a 10". He said it would probably just provide enough focused friction and heat to just slice through the plastic like a hot knife through butter. He was absolutely right! I just moved the plastic through the blade at a fairly slow steady speed. Only as fast as the disintegrating plastic would allow. Wish me luck! |
