Re: fein multi-master wheel tools for removing grout from stone tiles
Tina first the wheel does not spin on the multi-master it oscillates. So when its running and oscillating very fast where you see the edge of the wheel or blade may be an optical illusion. When you are removing the thin set from the field area you have to watch where the the thinset is being removed not where you see the blade. That area will be slightly out from where you see the blade.
