Arrived earlier today, a 125mm 18V LTX Metabo, with 25 No 115 discs when I had, understandably, ordered 125's, DOH !!
P.S.
My simplistic/intuitive understanding of "bursting" forces on a spinning disc, are that they are greatest at the periphery, what happens near the centre is not a factor.
So a 9" cutting disc designed not to burst at 6600 rpm, is actually being less stressed when run at 11000 after being worn down to 4.5".
Unless the disposable cutting disc is so highly engineered so that the outer cutting edge is stronger than the centre material,
but a visual inspection would seem to indicate homogeneous material and construction throughout.
I am only talking about cutting discs, the dished centre in a grinding disc, may well be a weak area, or at least, not intended to be used for grinding, but if the centre dish is the same on a 9" as a 4.5" I rest my case.
I tink this horse is now well flogged dead btw.
