Tool for cutting grooves in concrete

[ant1909]

How can I cut a 40mm deep groove that is 14mm wide or thereabouts in a concrete slab. I have 10 5m long grooves to cut. I thought I could use a floor saw but I cannot find anywhere where you can get blades that are thicker than 2-3mm. Do 14mm thick blades exist or is there a different way to do it?

never seen any blades that wide
if they exist they would cost a bomb
you may have to cut 2 parallel lines then chase the middle out
phil from pulvex may have a solution
google pulvex diamond blades

What may I ask is this for??

you should have cut them when pouring it or when it was green, but 14mm sounds like expansion material should have been used when pouring them the blanking piece removed and sealed.

or stack 4-5 blades together make sure the bolts long enough and they aren't rubbing on the guarding etc and lots of water and go real slow

Imhabe a wall chaser, that would be ideal its bassically a 4in grinder with two blades and a dust extraction system, you still have to break out the center but would do the job. Are you laying pipes?

bloody hell giles, you never fail to amaze me. Surely you don't expect people to do that? Apart from it being a potential health & safety hazard it is criminal. Cutters should only be used at full speed to. :O

10mm blades are avaible, used for cutting cable slots in asphalt/concrete for traffic signal cables/sensors, i have used one 10 years ago was not cheap but hired it by mm in a floor saw,
done even think of bolting blades together MSH

specialized core cutting company's have a concrete cutting tool basically like a chainsaw that have a width that your looking for but it wont be cheap. and never bolt blades for a saw together.

go real slow as in your forward movement cutting speed, oh wait lets use your logic yeah he should run round with the floor saw as fast as he can run thats real safe!

multiple stacked baldes are used to texture concrete for runways and other areas.

Nearby M5 has been diagnonally cut like that where there used to be a lot of standing water.

Giles this type of blade is manufactured as a single unit, not 5no aldi speciels and a long bolt...

[seanandruby]

floor saws, still saws, any saw is designed to run at full speed. Blades are made to be used at a set speed, not faster than it says on the label ie 500 rpm for a sthil saw. The blade you kindly posted is purpose made, as opposed to what you suggest, improvisation is a killer giles. I'm not having a go but i got slaughtered on here for posting on mick's thread and it got locked down because of the damage i could of caused the boss, your post could be equally, if not more, damaging if someone got maimd, or even killed.
