Snap cutter wheel dull.
The score and snap cutters take a little learning--Crain cutters cut on a pull stroke--nice machine
breaker foot can be positioned anywhere along the beam.
Monolit cuts with a push stroke--Breaker foot only at the end of the rail--nice ,but the Crain is more versatile.
The most difficult that I have found are the double rail cutters with the swinging little breaker foot.
With any of them you will know that you have a good score by the sound---a continuous zip as you pass over the tile--once and only once.
The scratch will be very small--all you are doing is causing a weak line in the glaze.
A firm and gentile squeeze on the breaker foot will snap the tile on the score line.---Mike--
