That's where the Tx range have an advantage then...clear line of sight and great for harder tiles.....when cutting tiles for paterns etc ..you need to cut accurately...that is the advantage rubi cutters have over these type of cutters..

I have the TX700n and it breaks anything i put in it...apart from a new highy glazed porcelenato CTD have brought out....and no amount of breaking power etc will crack these babies.....its just down to the design of the tile i guess.....
