Creating a new hole in a galvanised water tank

[watertight]

Guys,

Wonder if any of you could tell me the best way to produce a hole (approx 1 1/4") in a galvanised water tank.

The tanks is not corroded so shouldn't fall apart, too easily at least.

Your opinions/ideas would be appreciated.

Thanks Breezer.

I have a collection of holesaws (all cheapo ones admittedly). They fail miserably when trying to create a hole in a SS kitchen sink, is this because they are cheap or would all holesaws fail regardless?

If quality makes the difference then I'll opt for that option.

SS used for sinks is pretty hard,; for those a Q-max cutter is better. Galv tanks are quite soft so all but the cheapest holesaws should be ok.

I have to wonder if your use of an old galv tank is wise - another issue!

Cheers Chris,

Tank is in a school, council asked me to quote for the work to replace a ball valve, I advised updating the tank as it is 30 years old but the council was having none of it!!!!

I specified that damage may occur to the tank as a result of the process of creating a new hole and will get the estimate signed prior to starting work. I just don't want to get to the tank and be unprepared.
