Didnt know ( doh!)

Spin the wheel when power off to see if the bore is slightly off centre. Had once a few years ago with a wheel I bought for my SMS Clipper, changed it and all was fine after that.

Wheel is fine, it spins the correct way..
It cuts pretty good with the face of the tile upwards. All I'm saying is its even better when cut with the face down. Can't for the life of me explain why!:lol:

I have noticed this on my 9p too

i am sure as can be that you are not supposed to cut with face down. ive had the sigma 9m and 10m for more than 15 years and they are great saws but in fairness i have not used much on porcelain.

Well I'm baffled, but if it works then why not?

It's the angle at which the blade hits the glaze.
Upside down on the Sigma, the angle is increased closer to 90 degrees slightly.
I've noticed the same on my DeWalt. Normally the blade is set as low as possible but some glazed porcelains seem to chip less with the blade set just enough to get through the tile.

I sort of get that.
