are any of those blades any good for clay pavers?? As the blades we normally use for indian stone are not lasting more than 50 cuts on the clay pavers

[lutonlagerlout]

are you using water on the clays?
i have done a 50 m 2 drive with one of the obas ones,but the art is not forcing the blade and using water

Have not been using water or forcing the blade. But have tried a belle exttra hard materials blade and it is lasting a lot longer and still cutting well after a day of constant cutting. Cheers

i have been using a "spectrum tx10r" multi construction blade designed to cut hard materials and metal. for cutting clay paver's. I payed for £40 for it from Elliott's builders merchant, its best used dry (now not recommended by the hse), its fast, and lasting very well, it is also good as I don't have to change it if suddenly come across some metal I want to cut (old gas/water pipes, rebar)

You can flip them over in the grinder or saw which almost self sharpens them aswell ,not sure how coshur this is with health & safety mind!! :rock:

[Dave_L]

Not reccomended I'm certain!!

There is a way of regenerating a diamond blade, I read it in a leaflet that came with a JCB blade I'm trying out. Can't remember what it was; it was something along the lines of running the blade through a particular material......

[Mikey_C]

I remember reading somewhere that you can run a dull/blunt blade through a "soft" material to renew them, i never worked what was meant by it and the blade hasn't gone blunt yet so I haven't worried :p

[Dave_L]

Cheers Mikey, I knew I read it somewhere, but I've chucked out the leaflet.

Currently evaluating a 300mm JCB multipurpose blade, initial impressions are good both on concrete and tarmac. About £30/each.

i think that cutting concrete makes a grout that builds up around the diamonds and goes hard so that the diamonds are just "floating" and not biting into the intended material. if you take the blade off and lightly tap around the tip and the sides with a chipping hammer or a bar then give it a good wire brushing that should clear the grout, that goes for core drills to. if you need to run the blade through summet to clean it i would say sharp sand as that is abrasive. :;):
