Cutting Porcelain Paving
Porcelain paving slabs are 20mm thick, so they can’t be cut with tile cutters, unlike thinner indoor tiles. Specialist cutting equipment is required to cut porcelain paving slabs, and selecting the right diamond blade is absolutely crucial.
London Stone’s Diamond Blades
Our diamond blades are designed and manufactured in Italy. They have been specially engineered to meet the challenges of cutting through porcelain, one of the toughest paving materials available, with precision and minimal chipping.
Product features
Material: Manufactured from premium stainless steel, our diamond porcelain blades offer unmatched durability and cutting strength.
Design: The blades feature a continuous rim design, essential when cutting ultra-hard materials like porcelain. It ensures smooth, clean cuts, reducing the risk of chipping the edges of the porcelain slabs.
Sizes available: Available in various diameters—125mm, 250mm and 300mm—our blades fit both small and large grinders, petrol disc cutters and table saws. So, whatever your preferred cutting equipment, we can supply the right blade.
Wet and dry use: Optimised for both wet and dry use, these blades provide flexibility in various cutting conditions. Using them wet reduces dust and extends the blade life, while dry use offers convenience and a quick setup. We would always recommend using wet cutting, but there are situations where small electric grinders need to be used. In this situation, make sure to wear a suitable dust mask.
Here’s a table that shows the benefits of wet cutting:
Feature |
Wet Cutting |
Dry Cutting |
Dust Production |
Low: water suppresses dust |
High: no water used to suppress dust |
Cooling |
Water cools the blade, preventing overheating |
Requires periodic breaks to prevent overheating |
Setup |
Requires water source and setup |
Quick setup, no additional equipment needed |
Mobility |
Less mobile due to need for water |
Highly mobile: can be used anywhere |
Blade Life |
Extended: water reduces friction and wear |
Shorter: friction and heat wear down the blade faster |
Cut Quality |
Generally smoother, cleaner cuts |
Potential for more chipping and rough edges |
Usage Guide
The following is intended to be a basic summary of cutting with diamond blades. For further and more detailed information, visit How to Cut Porcelain Slabs, and check out our porcelain FAQ page or contact a member of our team, who will be happy to help.
Preparation: Secure the paving slab so that it can’t move suddenly during the cutting process. Mark your cut line clearly using a tape measure and a builder’s pencil or piece of chalk.
Cutting techniques: Check that your cutting equipment is in good condition and that the blade is fixed securely to the cutting equipment. When cutting, for the best results, cut both edges through first and then make several passes of the blade, maintaining a steady, moderate speed to avoid overheating the blade or cracking the slab.
Maintenance: Regular cleaning and occasional sharpening will help maintain the blade’s effectiveness.
