DAMI Abrasive Filaments: What You Need to Know‌

DAMI abrasive filaments are made by mixing abrasive grits—things like silicon carbide (SIC) or aluminum oxide (AO)—into good-quality nylon, then extruding the mix into filaments. The result is a material that’s stiff but still flexible and elastic, which makes it great for brushes used in grinding, finishing, polishing, and deburring. These brushes handle all kinds of surfaces, like curves, pipes, or uneven shapes, without messing up the workpiece’s dimensions or smoothness.

The nylon used can be N612, N610, or N6, and the abrasive grits include SIC, AO, WA, GC, or DM. The grit sizes range from coarse (#36) to fine (#1200), with diameters varying accordingly. For example, #36 grit has a 1.90mm diameter, while #1200 is as thin as 0.30mm. The grit load also changes with the size—30% for mid-range grits like #80-#320, 25% for coarser or finer ones like #36-#600, and 18%-20% for the finest (#800-#1200), with a tolerance of ±2%.

The filaments come in different styles: wavy, or straight. Standard items like #80-#500 are usually in stock and ship fast. One standout material is N612, which absorbs less water, lasts longer, and bends back into shape better than other types. It’s also closer to international standards, making it competitive with big global brands.

In short, DAMI abrasive filaments are a reliable choice for industrial surface work, offering a balance of toughness and precision. Whether you need heavy grinding or fine polishing, there’s a grit size and material combo that fits the job. And with standard items ready to go, you won’t wait long to get started.
