Issue cutting tile with sigma max - TilersForums.com

[Leroy Brown]

Evening all. I hope you are all well.

I am having an issue where I cannot cut a tile straight. The start and end of the cuts breaks off diagonally. Please see image attached.

I am cutting 10mm porcelain tiles.

Could someone also tell me how to set the height of the wheel for the thickness of the tile.

Thank you

Hi leroy. At the end of the guide bar there is an adjustment wheel. With the foot flipped down adjust the wheel so that scribe arm gap to the guide bar is around 5mm each end. Then scribe end to end. Bring the breaker back about an inch in from the tile edge and snap quickly, called shock break. Try that and see how you go.

Hi Dave. Thanks again for your willingness to help. Sorry for my ignorance Dave. So is the bar where the tile snaps on called the guide bar? So from the bottom of the wheel to this bar should be 5mm?

Will give this a go in the morning. Just went through 4 tiles trying to get it to cut straight.

The bar is what the handle slides along. So you adjust the handle to var via the adjustable wheel

Yeah, been playing with those wheels to try and see how it goes. Will try your advice in the morning. Thank you

So, I think I cracked it. Adjusted the height and Scored it lightly a few time and it is giving me a much better cut. Thanks for the help Dave.

Excellent, glad to help.

Shouldn't need to scribe it a few times though. Strange!

I have had some tiles that will not cut on a snap cutter, no matter what you do, years ago I was tiling a basement floor and was setting 8x8" (200mm) tiles.
The floor was over 600 square feet diagonal set, every single cut needed to be cut with a wet saw.
One thing you might try is to use less pressure to score and not ever score twice. The surface finish will also make a big difference, high gloss will cut better than rough (stone-slate) finish.
How long is that tile? You might need a bridge saw to cut them.
