The 6-inch P320 17-hole yellow sanding disc is specifically designed for primer sanding, surface finishing, coating pretreatment, wood surface preparation, and composite material processing.
This product features aluminum oxide abrasive, resin-on-resin bonding, and a Treated Paper backing, along with a 17-hole dust extraction design. It is compatible with common 150mm random orbit sanders used in automotive refinishing, woodworking, industrial manufacturing, and coating pretreatment applications.
Sanding discs manufactured by Aozhong strictly adhere to FEPA abrasive standards and utilize industry-standard sizes accepted in both Europe and North America.
Suitable for automotive refinishing, woodworking, metal fabrication, and composite material sanding where stable cutting performance and consistent surface preparation are required.
Designed for intermediate sanding stages, this P320 aluminum oxide sanding disc combines controlled cutting performance, efficient dust extraction, flexible backing, and fast hook and loop replacement.
P240 is commonly used after P180 and before P320 during multi-step sanding processes. According to FEPA standards, P240 abrasive grain size is approximately 46.2 μm.
The hole configuration allows dust to move through the sanding disc and backing pad into the extraction system.
Aluminum oxide provides controlled cutting action suitable for intermediate sanding stages.
The treated paper backing helps the sanding disc conform to curved surfaces while maintaining structural integrity during mechanical sanding.
The hook and loop backing supports fast replacement and stable disc attachment during repeated sanding operations.
