Diamond blade

To choose the right diamond disc, consider the available diameter and thickness (for example 115 mm / 10 mm or 230 mm / 10 mm) and match it to your tool (cut-off saw, angle grinder, etc.). Segmented discs improve cutting efficiency and reduce friction. For different materials such as concrete, masonry, tiles, or granite, choose a specific disc and check its segmented design—this helps with effective cooling and optimal dust extraction.

A segmented design helps create a fast, stable cut by distributing cutting forces. The spaces between segments allow for efficient cooling and dust evacuation, helping prevent overheating and premature wear. This setup is especially useful for continuous work on concrete, stone, and tiles, reducing rough edges and extending the disc’s lifespan. Match the diameter and thickness to your cutting depth and the tool you’re using.

Segmented diamond discs are widely suitable for concrete and masonry, providing a clean cut without excessive overheating. For tiles, marble, and granite, choose discs designed for the hardness of the stone and for the intended cutting depth and thickness. Some blades are available in thinner or reinforced versions for heavy industrial applications. Always check the manufacturer’s recommendations and consider practical tests to get the best results and avoid damage to the workpiece.

Wear proper protective gear (goggles, gloves) and make sure the tool is in good condition before each use. Follow the rated rotation speed and don’t force the disc into the cut. Keep the disc clean and ensure sufficient cooling during long work sessions. Use supports and guides when needed for straight, precise cuts, and replace the disc if you notice signs of wear or cracks.

For everyday professional use, you’ll typically find discs ranging from 115 mm to 230 mm, with common thicknesses around 10 mm and larger versions for industrial applications up to 16 inches. The 115 mm and 230 mm discs fit easily into most grinders and saws, while 9 to 16 inch versions are suitable for heavier machines and heavy-duty granite and tile cutting.

Discs intended for granite or marble usually have a segmented dirt id and a cutting architecture designed for fast cutting without overheating. For tiles and ceramic, choose finer segments and an appropriate thickness for clean, straight cuts without chipping. Also check the diameter and compatibility with your tool, because some discs are only meant for specific tools and may require proper adjustments.
