Whether you’re a Sydney stonemason cutting granite or a tradie slicing through tile or concrete, this guide will help you choose the right diamond blade for the job.
Whether it’s bluestone, marble, sandstone, engineered stone or porcelain, every material cuts differently. If your blade isn’t designed for the hardness, density, or moisture content of the material, it will burn out early, cause chipping, cut unevenly or slower, overheat your tool.
And in a busy Sydney job site where time is money? That’s the last thing you need.

Dry cutting is more common on outdoor jobs or where water isn’t available — but it:
