GMA MicroCut™

GMA MicroCut is the high-precision garnet abrasive for waterjet cutting of small, or tight tolerance parts. MicroCut is ideal for cutting thin, soft, and brittle materials, or when parts are nested closely together

The finely graded particle size allows operators to achieve superior edge quality with maximum precision.  The smaller particles also allow for a smaller orifice and nozzle combination, which results in less kerf or waste material. Ideal for electronics, medical devices, aerospace, jewelry, watchmaking and microtechnology components.

Industry Applications

Glass cutting
Plastic cutting
Medical devices
Precious metals

Why choose GMA’s waterjet products?

Engineered blends

Secure supply

GMA is the only global garnet supplier to manage their complete supply chain from source and processing to international distribution, giving you minimal disruptions to your consistent supply of garnet.

Quality badge

Consistent quality

Our high standards in processing and quality control ensures each batch contains consistently 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.


Superior performance

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 oversized 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 unique garnet provides the perfect balance between cutting speed and edge quality, requiring less garnet to make the cut while achieving the best edge quality. This results in direct cost savings and a longer operating life for your waterjet equipment.


Disposal and recycling

GMA has invested heavily in innovative ways to reduce landfill and reprocess garnet, with an expanding number of reprocessing facilities opening around the world.
