How To: Cut Porcelain


Porcelain is quickly becoming one of the most popular materials used in today’s kitchens, bathrooms and fabrication projects. Alongside this growing design trend, the concerns over silica content in engineered stone have driven people to seek new materials.

Materials such as porcelain, ceramic, UCS and Dekton typically come in slabs of between 12-20mm. However, the introduction of 6mm thicknesses built around a foam board substrate is becoming progressively more common. The guide below focuses mainly on the best method to cut 12mm or 20mm slabs. If you are looking to fabricate thinner slabs, get in touch for further advice or vary your fabrication method to suit.

Checking the surface

It is vital that your slab is secure on the saw bed to achieve a perfect cut. In addition, you’ll need to ensure your saw bed is level to avoid chips or breaks caused by vibration. Use our Black Nest Rubber Matting for the ultimate secure saw bed!

Choosing the right blade

Using the correct porcelain saw blade is a key factor when dealing with such delicate materials, and we have the one for the job. Using a specialised blade for cutting porcelain, ceramic and UCS, specifically developed with higher quantities of harder diamond is the best option for a chip-free cut, at efficient speeds.

Feeds & Speeds

UCS materials require very different feeds and speeds to traditional materials such as granite and engineered stone. However, with the right saw blade you can achieve feeds and speeds much more comparable to granite and quartz.

How much water?

The fragile nature of materials like porcelain means that whilst cutting, it’s recommended to apply as much clean water as possible, positioned straight at the tip of the blade, into the cut. It is important to use clean water, as this can affect the quality of the cut. If you think you need more water than your saw can apply, you could set up another water source to the cutting area.

Tension strips

Often, slabs of materials such as Neolith, Laminam, Lapitec and Dekton may have tension strips already built into the perimeters. If they are still attached prior to cutting, there is higher risk of the slab cracking or breaking during the cut. For maximum safety, we suggest you cut 25mm inward around the entire slab, beginning with the long edges, followed by the shorter sides.

Dangers of plunge cuts

Plunge cutting UCS materials can ruin your surface. Instead, we suggest you begin your cut from the outside of the slab and avoid moving back.

Sharpening your tools

The life of your tools and the quality of your cut is determined entirely by how your tools are maintained. Using our Sharpening Block will keep your blade in fantastic condition. Running your blade through the block when dry is the best method to achieve that perfect cutting edge. Otherwise, running quartz or engineered stone jobs between porcelain ones is often a good cheap option to keep your blade sharp.

Porcelain is a composite material, which means that each creator has their own unique characteristics, resulting in fabrication methods having to vary with each type.
