4x21" Industrial Grade Zirconia Grinding Belts
Our industrial grade zirconia sanding belts are a great choice for heavy duty grinding applications. Zirconia’s self-sharpening abrasive grains extend belt life up to 2.5 times longer than aluminum oxide. Zirconia fractures during use, continuously revealing sharp abrasive grain. Its durability makes it a great choice for knife makers, blacksmiths, welders, or anyone working with metals. While it will not match the longevity of ceramic abrasives, zirconia is a cost-effective alternative. These belts will work for both wet and dry applications. They are hand built in the USA.
