Best way to cut 20mm porcelain - TilersForums.com

[Italy]

Our sister company sells a lot of 20mm porcelain. As a general rule a powerful wet cut bridge saw will give the best results. Dry angle grinder porcelain blades can work well. Stihl type petrol saws are very difficult to get straight cuts and it can be hard to source porcelain specific blades. Always go for porcelain specific blades. Pre-cut the end of the cut to prevent the cut 'pinging' and consider cutting in two stages. If cutting 'L' shapes pre drill the cut corner to reduce risk of 'pinging'.
Sigma Kera-Cut bar system for grinders is probably our favoured option. Easily transportable and simple.
It is very, very hard to make a decent profiled edge on site with 2cm porcelain, and some porcelains will not look good profiled. TileFix has a great range of 316 marine grade stainless steel edging in these situations;

Can this level of finish be okay?
or is it scarce?
dry cutting.
just to understand what you mean as a standard of finish
thanks

I was talking about an edge detail, i.e. an exposed step. a saw cut edge on a step for 2cm will most likely be unacceptable, a formed edge step can look great but it very difficult and a lot of 2cm porcelain would not look good.

Have you tried scoring the tile with your tile cutter and then tapping the back of the slab with a pin hammer along the reverse of the scoreline?...... It is worth a try (depends how big the tiles are I guess but I did it OK on 600x600 20mm)

Got a 9inch rubi blade arrived today for dry cutting cuts beautifully and Dural is specially making some brushed 20mm trims for the steps
