Right, hiring a petrol 300mm stihl saw from Jewsons, 38 quid for a weekend, diamond blade charge 19 quid per half-mm. Does that sound reasonable ? I have to cut though 80mm concrete slab, total cut length max 10 metres I would guess. But - how much will the disk wear ? I mean, it depends on the disk qualilty. Can anyone give me a vague idea ? Also, any techniques to reduce wear on the disk ? Cheers, Simon.

What about buying something like the top of the page here ?

Buy the dewalt 9 inch leccie jobbe from screwfix, with a blade, all in for under 125. I would not be without mine. The dimaond disk cuts a shed load of stuff, but find one that will cut embeded steel - some don't.
I would guess with your cutting an 19 quid per 1/2 mm, you will be better to buy your own disk, and am basing this on my guess that your concrete has steel mesh in it.

Well, I've done it now. I hired a stihl saw (actually a Partner K650) and used the blades I posted about. I cut the roof slab with 5 cuts and levered up the strips and slid them off the roof down a timber ramp with the help of 2 friends. The slab was propped using timber props I made. The concrete was actually quite lightweight with some thin reinforcing steel that I didn't end up cutting through. Wear on the disk was quite slight. Cheers, Simon.
