Angle grinders are widely used for cutting tile, stone, masonry and other materials, but the blade must be compatible with both the material and the machine.

Check the Grinder First

Before selecting a blade, confirm the grinder's permitted disc diameter, arbor and speed requirements. Common markets use different grinder sizes, including 100 mm, 115 mm, 125 mm, 150 mm, 180 mm and 230 mm classes.

Use only a blade that is designed and rated for the equipment and application.

Match the Blade to the Material

For concrete and masonry, segmented diamond blades are common. For ceramic and porcelain, thin turbo or continuous-edge designs may be preferred for cleaner cuts. Vacuum brazed diamond discs can be used for certain specialized multi-material applications depending on the product design.

Think About Cutting Quality

A construction cut and a visible tile edge have different requirements. For tile, users often prioritize low chipping. For masonry, productivity and durability may be more important.

Wet or Dry?

Many angle-grinder applications are dry, but product designs differ. Follow the blade and tool instructions. Do not introduce water unless the equipment is designed for wet operation.
