Blades for cutting concrete with cut off saw.
Discussion
Hi all,
Found myself the proud new owner of a STIHL cut off saw with approx 100-120 linear metres of concrete to cut to 90mm depth (don't ask me why lol). Before I start on my endeavour, the topic of finding the right blade and understanding how many blades I'm going to get through doing this has come up. I seem to be able to find them anywhere from £10-£200 with lots in between. Does anyone have any experience here on which blades would be best and what sort of lifespan I can expect? Appreciate this is a bit of a niche one, cheers!

Depends on the size and I assume dry cutting?
Last I bought was a fancy segmented Bosch Pro one, not cheap but has lasted ages with minimal wear while a cheap one managed one cut.
The expensive ones are usually going to last a *lot* longer, some of the cheap ones can be like cheese.
Does depend on how abrasive what you're cutting is.

It's a 300mm saw (TS410), and it'll be all wet cutting about 90 ish mm deep. What you're saying definitely stacks up with what I've been reading, I'll have to take a look at the Bosch one. Would you have any rough idea of how many metres I'd get out of a good quality blade like the Bosch one you mention?Last I bought was a fancy segmented Bosch Pro one, not cheap but has lasted ages with minimal wear while a cheap one managed one cut.

Would you have any rough idea of how many metres I'd get out of a good quality blade like the Bosch one you mention? I know that's probably a very difficult one to judge. Concrete is probably C30 and been down around 70 years. Last I bought was a fancy segmented Bosch Pro one, not cheap but has lasted ages with minimal wear while a cheap one managed one cut.

Couple of blades should see you right. The difference may be steel reinforcing!
Luckily there's no rebar in it. Only getting through a couple of blades would be a result. Do you have any recommendations aside from the one made above?wolfracesonic said:
Can t help with blade recommendation but hiring a cart to put the saw in would save your back I would have thought. What are you doing, installing linear drains?
No, it's for a barn built in the 60's out of lovely stone, someone then had the bright idea to pour a concrete path/narrow road around it and not leave a gap between that and the building, since then the concrete has sunk in places and is generally looking completely dilapidated. Had a go with a breaker but even being very careful it started to damage the mortar and stone. Builder suggested going round the edge very close with a cut off saw and then breaking the bulk of it out and doing the last inch or so with something a little more subtle.Gassing Station | Homes, Gardens and DIY | Top of Page | What's New | My Stuff
