How to Cut Porcelain Countertops & Slabs

|

Porcelain is a trending material choice for clients who love sleek, modern surfaces. This engineered material is incredibly durable making it more resistant to heat and scratches. Whether you’re cutting porcelain slabs for countertops, backsplashes, or wall features, using the correct tools and techniques is essential to achieve the precision and smooth finish your clients expect.

This article outlines the key requirements for cutting porcelain and how Park Industries® can optimize your fabrication process.

Essential Requirements for Cutting Porcelain

Cutting porcelain requires a specialized diamond blade, as porcelain is an incredibly hard and brittle material. Diamond blades embedded with synthetic diamonds are essential for handling porcelain’s unique density and hardness, providing clean cuts that minimize chipping and preserve the slab’s integrity.

However, the diamond blade alone isn’t enough. A water-cooled system is crucial when working with porcelain to manage the heat and control dust produced during cutting. This cooling process reduces the risk of cracking and ensures a clean, polished edge, which is especially important given porcelain’s tendency to chip.

For fabricators looking to optimize their porcelain-cutting capabilities, CNC saws and sawjets provide the precision and efficiency needed for intricate cuts and consistent results, maximizing efficiency, and reducing material waste.

How to Cut Porcelain with a handheld saw

If you’re cutting porcelain manually without CNC saws, the process requires a steady hand and careful attention to detail. Start by marking your cut line on the porcelain slab using a grease pencil or chalk. This guide will help ensure accuracy throughout the cutting process.

Next, securely clamp the slab to prevent any movement while cutting. Use a handheld saw equipped with a diamond blade rated for porcelain, and make slow, steady passes. Begin by lightly scoring the marked line to create a shallow guide, which helps prevent the blade from wandering during deeper cuts.

Because porcelain generates significant heat, always use water to cool the blade and control dust. Make shallow initial passes, gradually increasing the depth with each pass until you cut through the slab completely. With patience, the right tools, and proper technique, you can achieve smooth, precise cuts that highlight porcelain’s elegant finish.
