Rubi cutter help

Thanks Dan! There are quite a few brands here. I used Knauf flexkleber (flexible adhesive) Extra and their flexible grout Flexfuge.

Ok, I said I'd give some feedback, so here goes.

The Sigma scores in a straight line and breaks nearly every tile perfectly, even up to 2 cm in width. I say nearly, because the first tile I scored, I probably didn't press hard enough and it broke. Since then, however, not a single tile has been damaged. Additionally, the tile can be broken over the entire length, which helps when trying to remove small scored sections in the middle of a tile. This didn't work properly on the Rubi.

The only minor issue I have is that the cm markings don't completely line up with the scoring wheel. This means I have to recheck the settings with a ruler to be sure before cutting. Also, scoring backward over the edge before I push the lever away cuts into the plastic above the built-in ruler. It's here that you see that the wheel is not at 0 cm.

Anyway, all in all, this is worlds better than either the Kaufmann I tried (the Germans seem to love these) or the Rubi.

The Kaufmann was rather brutal, and the wheel didn't score well. Both the Rubi and the Sigma score like butter. The Kaufmann sort of gouged its way across with a lot of effort and splintered the glaze. The wheel was a gold one from the pro series and also TiN coated, but it didn't work well at all. I made quite a few test cuts, and with any less pressure, the tile would break to the side. Additionally, when the tile did break correctly, the inside edge wasn't clean like the Rubi and Sigma. Here, it was often wavy and full of bumps, i.e., not a flat surface on the cut side.

The machines I tested were:

• Rubi HIT-850 N - Cuts well but limited options and guide rails not straight.
• Kaufmann TopLine PRO 630 - Bit of a blunt instrument with poor to limited results.
• Sigma 4 BN NEX - 62 cm - Very impressed, cuts very well and very reliably!

I'm extremely glad I switched over to the Sigma. Thanks for the help, guys! 🍺

P.S I've attached a pic of my Sigma with the cutting wheel slightly off-center for reference. Perhaps this can be adjusted?

0.5mm. I’d be ok with that lol. Glad you like the suggestion to try Sigma.
