800 mm tile cutter for porcelain

Updated: October 2026

The porcelain is already in the house. The box might say 10 mm, or it might only say porcelain. You need a yes, a no, or a stop before you score the first floor tile. An 800 mm tile cutter for porcelain can snap smooth porcelain around 8–10 mm when the rail stays stiff. It is the wrong tool when the face is textured, when the tile is stone, or when the thickness sits past the printed band. The Products Compared editorial team read the four listings in the [tile cutter 800 mm comparison](/hub/cutting-tools/tile-cutter-800mm) on 15 October 2026 and did not run a lab cut.

What porcelain means on these listings

Porcelain in a title is a material word. It is not a thickness. Glazed ceramic around 6–8 mm is the ordinary job. Smooth porcelain around 8–10 mm can snap if the rail stays stiff. Walls and Floors move textured porcelain, and porcelain thicker than about 10 mm, to a wet saw. TOPWAY's technical block does not state a thickness. CGOLDENWALL's bullet says 0-15 mm, and the carton is 63 cm against a 0-800 mm claim. YATO's dump does not state a thickness. The maker's page says 16 mm, and the listing weight is 7.51 kg. ROJOO's bullet says 6-15 mm. Length and the diagonal are on the 800 mm tile cutter buying guide.

Around 10 mm, if the rail stays stiff

Walls and Floors put the manual limit near 10 mm for porcelain that is not textured. Screwfix puts a manual limit at stone and at about 16 mm. Neither figure is a test of these four beds. The Bihui C-Lion, outside this set, warns that tiles thicker than 15 mm are not always possible by hand. TOPWAY UK reviews cite clean snaps on 8 mm porcelain and on 10 mm porcelain when the wheel was not forced, and also a struggle at 10 mm or thicker. A 14 mm story does not fill the blank thickness cell. ROJOO states 6-15 mm, and the nine UK reviews do not give a thickness. If the rail rises on an offcut, stop. ROJOO is the top pick for that printed band. TOPWAY is the best value on a long carton, with no thickness printed. None of the four prints 20 mm.

The wheel the box does not measure

RUBI maps wheel diameter to the glaze: about 6 mm for wall ceramic, 8–10 mm for smooth floor porcelain, and 18–22 mm for textured or thick porcelain. Titanium, carbide, and a Ti coating are materials, not those diameters. TOPWAY prints a titanium-alloy wheel and spare ASIN B07P6FFL25, with no diameter. CGOLDENWALL prints carbide, with a spare in the box and no ASIN. YATO prints a Ti-coated carbide blade and no diameter. A 22 x 14 x 2 mm figure beside that model is the carbide blank, not an 18–22 mm scoring wheel. ROJOO names neither a material nor a spare.

When the bed is the wrong tool

Put the bed down when the face is textured, or when the tile is natural stone. CGOLDENWALL's title lists granite and limestone. The UK review does not show those materials. Put it down when your box is thicker than the band the listing prints. TOPWAY and the YATO dump print no thickness. ROJOO prints 6-15 mm. If the bar has already bent on a 10 mm offcut, more pressure will not stiffen the frame. Water, dust, and voltage are on the tile cutter vs wet saw page.

Common questions

Can this bed cut all porcelain?
No. Smooth porcelain around 8–10 mm can snap on a manual bed if the rail stays stiff. Textured porcelain, and porcelain thicker than about 10 mm, are wet-saw jobs in the Walls and Floors guide. A title that says porcelain does not include every thickness and every face. Stone is a separate stop. If the rail flexes on your offcut, stop.
Is 10 mm smooth porcelain the same job as textured porcelain?
It is not. Smooth 10 mm porcelain is the region where a stiff manual rail can still snap a straight score, according to Walls and Floors. Textured porcelain goes to a wet saw on that guide, because the score breaks up on the ridges. RUBI puts smooth floor porcelain on an 8–10 mm wheel and textured porcelain on an 18–22 mm wheel. These listings do not print a diameter.
Why is a titanium or carbide wheel not a diameter?
Titanium alloy, carbide, and a Ti coating describe the material of the wheel. RUBI's sizes are diameters: about 6 mm for wall ceramic, 8–10 mm for smooth floor porcelain, and 18–22 mm for textured or thick porcelain. TOPWAY, CGOLDENWALL, and YATO name a material and no diameter. ROJOO names neither. You cannot tell from the title whether the wheel matches a 10 mm floor tile.
What is the YATO 22 x 14 x 2 mm figure?
It is the size of a carbide blank, the piece the wheel is formed from, not the diameter of the scoring wheel. RUBI's 18–22 mm range is a wheel diameter for textured or thick porcelain. Reading 22 mm on the blank as that wheel would overstate what the amazon.co.uk dump shows. The dump does not state a thickness. The listing weight remains 7.51 kg.
Does the CGOLDENWALL title's granite and limestone follow from the 0-15 mm bullet?
They do not. The title lists granite and limestone beside porcelain. The bullet says 0-15 mm. The only UK review gives no material. Granite and limestone are stone, and Screwfix puts stone at the manual limit. The carton is also 63 cm, so the length is unconfirmed. Do not plan a stone floor on that title.
