OUR GARNET

The GMA advantage

GMA GarnetTM is a strong, natural mineral that outperforms other garnets due to its unique properties and our advanced processing methods, refined over 40 years. Unique grain hardness, toughness, density, and angularity ensure perfect edge quality on any material with a thickness of up to 30 inches.

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.

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.

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.
