Stainless drilling

[mcgrath]

I have a stainless Swan boiler(similar to burco) that I've been just heating water with. I want to replace the rubbish tap on it with a half inch ball valve.
Will require widening the opening. Anyone local know whats involved and have the tools etc? No panic on it. It's just on the to do list..

All you need is a step drill. Will talk on Tuesday.

Cool..

I have a qmax cutter that I used on my buffalo. I think its 20.7mm. Let me know if you need it

Cool..

And importantly a source of cool water to cool the steel and keep the cutter cool.

Slow and cool is the way to go when drilling/machining stainless.

A q-max cutter is different as its just a punch that cuts the hole cleanly without heat. Ok for thin pots but maybe not a keg!.

As Jacob said more chat on tuesday. Maybe we should start up "Tool Time" whereby people who know talk a bit about thye toosl and techniques?

Aye those wee Q-Max cutters are great - used one at the weekend there to punch a hole in my SS stockpot.

Any hints where you got the q-max cutter?
