Porcelain slabs, with their large format and exceptional hardness, have revolutionized modern tiling in both residential and commercial spaces. Cutting these slabs demands precision, strength, and reliability-qualities that Rubi, a leader in tile cutting technology, is renowned for. But with Rubi's extensive lineup, which model is truly the best for porcelain slabs? This comprehensive guide explores the top Rubi porcelain slab cutter models, compares their features, and provides expert insights, complete with images, video walkthroughs, and practical tips.

Ensure your work area is clean and stable. Place the porcelain slab on a flat, secure surface.
Use a pencil or marker to outline the desired cut on the slab.
Assemble the modular guides (if applicable) and attach the suction cups firmly to the slab for stability.
Position the scoring carriage at the start of your cut. Apply steady, even pressure as you move the carriage along the guide, scoring the surface in a single pass[7][10].
Use the breaking system (nippers or pliers) to apply progressive pressure along the scored line, snapping the tile cleanly.
Use a diamond polishing pad to smooth any rough edges for a professional finish[7][10].
Wipe down the guides and scoring wheel to remove any debris.
- Clean Guides Regularly: Remove dust and debris after each use to ensure smooth carriage movement[9].
- Lubricate Sparingly: Use only a few drops of maintenance oil on the guides, then wipe dry to prevent residue buildup[9].
- Protect Scoring Wheels: Store the cutter and accessories in their designated case or bag to avoid damage.
- Check Suction Cups: Ensure they remain free of dust and maintain their grip on rough surfaces.
