The Advantages of GMA Waterjet Garnet

Reliable Supply

GMA is the only global garnet supplier to manage the complete supply chain from source and processing to international distribution. We own our mines and processing plants in Australia, USA and the Middle East. 

Guaranteed Purity

With our unmatched processing, each batch contains highly accurately sized grains of the highest quality almandine garnet. A bag of GMA Garnet™ contains as much as 98% pure garnet. Uncontaminated garnet enables faster cutting and cleaner cuts.

Higher Quality Cut

GMA’s waterjet abrasives’ unique grain hardness, density and toughness ensure the highest production rates and the perfect edge quality with the first cut. Our waterjet garnet can cut virtually any material with a thickness of up to 24 inches. 

No Oversize Grains

GMA Garnet™ has no dust particles or fine grains that hinder garnet flow or oversized grains that block focusing tubes. This means you can count on uninterrupted, efficient cutting from your equipment.

Reduced Abrasive Consumption

Our subangular grains provide the perfect balance between cutting speed and edge quality. The alluvial garnet grains result in direct cost savings and longer operating life of your waterjet equipment.
