Cast soil section replacement

[WC1]

there ok just watch your speed and keep the blade cool eg lubricate

So I did a worst case scenario test and blasted thru at full speed with no cooling and for me the debate is over, super clean cut, hardly any dust and through in a minute or less on an old bit of 3 inch "glwyned" timesaver cast.
The blades probably fairly cooked, some of the ends of the carbide tips are off but for a tenner off Amazon for 9inch I'll keep a couple in hand.
This was Milwaukee but I'm sure the others will do as well.
Very impressed

Well done just like I work, stuff the thinking about how not to do it, dream up problems....you just got on with it and it’s done. Often too many people over think stuff you just went for it

Excellent work and thanks for sharing. I wonder if cooling and lubrication would have saved the saw? I suspect that a successful and fast cut is easily worth the cost of the blade though anyway. Lubing and taking time might end up costing more than the saw was worth. I would have surely done what Shaun said and taken my time and used cutting oil as it makes sense to me to do that as well.

The very few times I've had to cut cast iron live in a customer's house I used one of these and I found it a bit nerve-wracking. I was nervous it would cut and crack the pipe.

I prefer the idea of sawing so your demo is good to see.

I never liked using "snapper" types.
We cut this one a while back with an angle grinder.
This pic was taken to illustrate the blockage in the pipe, but look at the variation in wall thickness - in some places it's half what it is in others and ive never liked the worry of using a snapper.
Carbide recip for me now for the few times a year I'm cutting cast.
I'm also now thinking about rebar and other metalwork we sometimes cut.
Unfortunately it'll also be useful to naughty boys getting in places they shouldn't.
