The world’s most popular waterjet garnet
GMA waterjet abrasives are engineered for peak performance, accuracy, and speed. Refined over 40 years alongside industry experts, our products are the first choice of operators who demand ultra-precise waterjet cutting.
GMA’s world-class processing facilities guarantee every batch contains consistent-sized grains of the purest garnet, ensuring steady abrasive flow, reduced consumption, and less downtime for maintenance and parts replacement.
The GMA advantage
Engineered for precision cutting
GMA’s range of waterjet cutting abrasives strikes the perfect balance of cutting efficiency and edge quality for results that improve production uptime.
Optimum hardness
The harder the grain, the better it cuts. Our garnet is hard, tough, and dense – the perfect combination for effective cutting, with low abrasive consumption and excellent edge quality.
Consistent grain sizing
Inconsistent grain sizing causes blockages, creating unsteady abrasive pressure and flow, fluctuating cutting speed, and poor edge quality.
Our processing methods ensure every bag contains the most precisely-sized grains of garnet, accelerating your production, and reducing the frequency of expensive parts replacement.
Cleanliness and purity
Dusty, dirty, or impure garnet impacts cutting performance, causing inconsistent pressure, frequently blocked focussing tubes and filters, increased wear and replacement of focussing tubes, and potential damage to the cut parts.
GMA’s advanced processing methods produce the cleanest, purest, dust free garnet for the best results and the highest productivity.
