How to cut 20mm porcelain tiles

In this guide, we talk you through how to cut 20mm porcelain tiles. 20mm (2cm) porcelain tiles have a much higher tensile strength than the standard 10mm (1cm) tiles and can therefore prove more difficult to cut. It is important that when cutting 20mm porcelain tiles the correct cutter and blade are used to avoid damages to both the tiles and cutting blade.

Best blade to cut 20mm porcelain slabs

The recommended blade for cutting 2cm porcelain is our specially designed and exclusive RUBI TVP SuperPro range of cutting blades. The blade also features a unique placement of diamonds, meaning superior cutting performance.

Using an angle grinder

Produced by a blade specialist, DEX brings you the ultimate cutting blade for 2cm tiles. This 115mm diamond blade is made with mesh segments to ensure minimal chipping when using your angle grinder, cutting up to 120 linear metres!

Alternatively, the RUBI TLG Superpro blade has been exclusively designed for Topps Tiles. Rigorously tested to cut up to 30 linear metres of 2cm porcelain tiles, the blade is extremely resistant to heat and designed to cope with the extra pressure that is exerted on a blade when cutting 2cm porcelain.

High quality diamonds are used on the 115mm blade, along with a steel core to give the blade longevity and performance when using an angle grinder.

Using an electric cutter

The second recommended method for cutting porcelain slabs that are 20mm thick is with an electric cutter with a ‘Plunge’ capability (the ability to adjust the cutting depth of the blade) to allow cutting the tile in two passes.

Firstly, set the blade height to cut through half the depth of the tile (1cm) and allow the blade to pass/cut through the tile. Once cut, set the blade height to complete the remaining depth of the tile and allow the blade to cut through the tile without force.

How to cut outdoor porcelain tiles

To cut outdoor porcelain tiles, you'll need a wet saw with a diamond blade. First, mark your tiles with a pencil before placing them on the wet saw. Make sure to take the necessary safety precautions, such as wearing goggles and gloves, before starting the machine. Following the guidelines, slowly and steadily make the cut with the blade to avoid chipping the tiles. Let the saw do all of the work, and stop to check your progress periodically to ensure an accurate cut.
