CGW 52773 5" Dia 50-Grit Green Zirconia Y-Weight Cloth With Grinding Aid PSA DOR Sanding Disc

CGW CGW52773 5 inch diameter PSA sanding disc features a Y-weight resin bond polyester cloth backing with two coatings of grinding aid, designed for precision finishing on hard metals. The 50-grit zirconia abrasive provides aggressive material removal while maintaining shape and edge stability, which helps reduce loading during long grinding sessions. This disc is intended for use with orbital or random orbit machines and is suitable for applications involving cast iron, nickel, and stainless steel surfaces where a balance of material removal and finish quality is required.

The disc’s PSA (pressure-sensitive adhesive) backing simplifies quick, clean mounting to compatible sanding systems, enabling fast changes and reduced downtime on busy production lines. Zirc-inspired zirconia grains offer improved durability and heat resistance compared to some standard aluminous abrasives, making them a practical choice for metalworking tasks that generate heat and require steadier performance. The combination of Y-weight cloth and grinding aid helps to manage grinding temperatures and reduces heat-affected zones when working metal substrates.

For procurement, each disc is a standalone item, with a packaging quantity of 50 discs per box, making it suitable for maintenance inventories and recurring jobs. When selecting this disc, ensure compatibility with your sanding tool’s disc size and attachment method, and verify that 5" PSA discs are a fit for your machine’s clamping system and pad. Regular inspection of the backing and abrasive surface, along with prompt replacement when performance diminishes, will help maintain consistent results on metal-finishing tasks.
