Thanks! Traps for beginners, I took the manufacturers rating as for the disk. Turned out it was for the teeth. Googling the correct psi. Gives me 14700rpm, so I won't worry as much when I'm next cutting concrete. Thanks again
Hi.In a previous thread(404-167467) the bursting speed for a spinning steel disc was quoted(rule of thumb)as v=sqrt(10*s) where v= velocity in f/s
And s=tensile strength.in psi.
I applied this to a 14 inch concrete cutting disk (6000 psi tensile...
