3. Can I cut porcelain stoneware with the angle grinder?
The angle grinder is a quick and inexpensive way to cut porcelain stoneware tiles to size. Here are the most important advantages and disadvantages at a glance:
Advantages: Less expensive diamond cutting disc than required for the wet cutting table; almost everyone has an angle grinder available; high degree of flexibility
- Cons: Long straight cuts can be difficult for an untrained user to make. In addition, cutting thick porcelain stoneware can take a particularly long time.
If you decide to use the angle grinder, you should make sure the edges are clean.
The quality of the edges is not always 100% optimal, but you can counteract this with a sanding pad for sanding tile edges . After the cutting process, simply pull along the cutting edge a few times and resharpen it.
The quality of the tile edges is also largely determined by the quality of the tile or fine stoneware cutting disc.
The following applies: the higher the quality of the diamond cutting disc, the more beautiful the edges.
3.1 Step-by-step instructions for cutting porcelain stoneware tiles with the angle grinder:
- Attach a 125 mm diamond cutting disc to the angle grinder, preferably with a quick-release nut.
- Mark the cut edge on the porcelain stoneware tile.
- Leave the tile overhanging so the cut edge is exposed and doesn't cut into the underlying material.
- Immerse the diamond blade in the edge area and slowly cut along the cutting edge.
- This should be possible without any problems up to a material thickness of 20 mm.
- Clean the edges of the porcelain stoneware tiles after cutting.
4. How do I cut porcelain stoneware with the cutting table?
The cutting table is the most precise and cleanest way to cut porcelain stoneware.
Here are the most important advantages and disadvantages at a glance:
Advantages: The cleanest and most precise method when cutting fine stoneware. Very suitable for particularly large tiles.
- Disadvantages: difficult to obtain; high price; generates a lot of fine dust
When cutting porcelain stoneware on the cutting table, you should definitely use additional water cooling.
From my experience I can tell you that you can achieve significantly better and more precise cuts and edges with the additional use of water. In addition, the diamond cutting disc will last much longer and is less stressed.
For me, wet cutting is simply part of cutting thick porcelain stoneware slabs.
4.1 Step-by-step instructions for cutting porcelain stoneware with the cutting table:
- Attach a water connection.
- Attach a porcelain stoneware diamond cutting blade to the tile cutting table. As a rule, these are discs with a diameter of 180 mm , 230 mm, 300 mm or 350 mm. You can find the right diameter for you on the imprint of your machine.
- Turn on the machine and the water supply.
- Place the porcelain stoneware tiles or patio slabs on the designated spot.
- Cut the porcelain stoneware tiles with a little light pressure along the desired cutting edge.
- It is best to check during cutting whether the required cutting depth has been set correctly.
5. Can I also cut fine stoneware tiles or patio slabs with the tile cutter ?
The tile cutter is another option for cutting porcelain stoneware tiles to size. Here are the most important advantages and disadvantages at a glance:
Pros: Lower price than the cutting table; easy handling, often already available.
- Cons: Not suitable for thick tiles; higher chance of damaging the tile when cutting. Cutting large format tiles is not possible with a conventional tile cutter.
If you decide to use a tile cutter, you should definitely pay attention to a high-quality tile cutter that can withstand the resulting forces and is designed for the desired tile size.
6. How do I cut porcelain stoneware without fraying?
A common problem when cutting porcelain stoneware tiles is the fraying of the cut edges.
Tip from my experience:
With some porcelain stoneware tiles and patio slabs, it can help to stick a piece of adhesive tape on the desired cut edge to prevent fraying.
You should try this on a discarded piece of porcelain to see if it works for your material.

Should you cut porcelain stoneware or break it?
That depends entirely on the thickness and size of the porcelain stoneware tile as well as the local conditions and the machines available. I would argue that I would generally always prefer 2cm thick and more porcelain stoneware slabs cut one way or another.
Is it safe to cut porcelain stoneware tiles with an angle grinder?
Cutting porcelain tile with an angle grinder can be safe as long as you use the right equipment and technique. It is important to use a diamond blade rated for cutting porcelain stoneware tiles and to ensure the tile is securely fastened. It's also important to wear protective clothing, including goggles and a dust mask, to protect yourself from dust and debris.

Cracks can occur if too much pressure is applied to the tile or if the cutting machine is not sharp enough. It is important to cut the tile slowly and evenly and to ensure the cutting machine is in good condition and sharp. Also, use enough water to cool the tile and minimize cracking.
