3 x 21 Aluminium Oxide Sanding Belt KY517

Product Description

The 3 x 21 Aluminium Oxide Sanding Belt KY517 is designed for heavy-duty metal grinding, deburring, weld removal, rust cleaning, and surface finishing applications. Manufactured with premium KY517 calcined aluminum oxide abrasive grain and durable Weight-Y polyester cloth backing, this sanding belt delivers stable grinding performance, excellent durability, and long service life for industrial and workshop use.

Compared with standard aluminum oxide sanding belts, KY517 calcined aluminum oxide provides better heat resistance, smoother grinding performance, and improved wear resistance during continuous grinding operations. It is especially suitable for stainless steel processing, carbon steel grinding, metal fabrication, and general industrial surface preparation.

The sanding belt features strong lap joint construction for higher joint strength, smoother running, and better grinding stability during high-pressure applications. Butt joint and bi-directional joint are also available for customized requirements.

Suitable for portable belt sanders, backstand grinders, and industrial sanding machines, the 3 x 21 sanding belt is widely used in metal fabrication workshops, weld seam grinding, edge grinding, rust removal, and surface finishing operations.
