How long does diamond abrasive filament last compared with silicon carbide or aluminum oxide?

Diamond filament wins on hard stone, and GrindX grades push the gap further.

On hard natural stone such as granite, diamond abrasive filament maintains cutting power far longer than silicon carbide or aluminum oxide filament, which lose their edges faster and need earlier brush changes. Within the GrindX™ range, CORE DIA is engineered for high-efficiency grinding with a 10 to 15 percent longer service life than comparable products, while PRIME DIA adds enhanced wear resistance for an additional 25 to 30 percent service life on top.

How to judge life in your own plant

  • Track brush hours against output area, not just hours, so different abrasives compare fairly.
  • Watch surface quality drift; rising finish roughness usually signals the economic end of brush life.
  • Test one GrindX™ brush against your current filament on the same stone batch before switching the line.
