Zirconia alumina is an ultra-tough, synthetic abrasive which provides a free, cool cut for high stock removal applications. It is tougher and sharper than aluminum oxide. It has a micro-crystalline structure which allows for controlled breakdown and self-sharpening.
- heavy-duty snagging and grinding of all ferrous and non-ferrous metals
- abrasive planing of wood, plywood and particleboard
- grinding fiberglass, rubber and plastics
With an open coat, 50% to 75% of the coated abrasive surface is covered by abrasive grain. There are evenly spaced voids between particles of grain, helping reduce the effect of loading caused by wood dust or metal particles.
