Features:*Scope of application: suitable for polishing shapes such as marble/quartzs stone/tiles.*Using high-quality material, high hardness, quick cutting, high density and not easy to fall off.*The brazing process does not lose sand, and you can grind it wet or dry. Brazing technology is wear-resistant and durable.*The substrate is made of high manganese steel, which is integrally formed, and has good shock resistance, compression and impact resistance. It will not be deformed or broken during use, and the work is safe and secure.* Easy to install and use.Notice:1.Actual color may be slightly different from the image due to different light effect2.Please allow 1-3cm deviation due to manual measurementDescription:Specification:Grinding thickness 10mmGrinding thickness 20mmGrinding thickness 25mmGrinding thickness 35mmGrinding thickness 40mm
