Diamond plates

Diamond plate for concrete

High-performance diamond plates for grinding all types of concrete on site.

The diamond plate for concrete is an essential consumable for surface grinding. Designed to remove laitance, open up porosity or level a slab, it combines high-density diamond segments with a bond suitable for the substrate hardness. Sept Tools selects its plates from proven European suppliers and guarantees perfect compatibility with its brushless grinders. Whether you are preparing a screed before applying epoxy resin or stripping a parking slab, this consumable ensures uniform attack, predictable longevity and controlled surface finish.
