This sanding disc is suitable for automotive sanding, metal sanding, primer sanding, paint stripping, body filler sanding, composite material sanding, and surface finishing. P80 grit is typically used for the coarse sanding stage, followed by finer grit sanding.
Product specifications are based on the provided product images, common 6-inch sanding disc dimensions, and standard conversion practices in the abrasives industry. Final specifications, including hole patterns, backing thickness, grit range, packaging, and private label printing, can be customized according to the buyer’s requirements.
The 41-hole purple ceramic polyester sanding disc P80 is designed for automotive body repair, metalworking, woodworking, composite sanding, and industrial maintenance.
Suitable for coarse sanding, material removal, surface leveling, old coating removal, and pre-treatment before painting or recoating.
The 41-hole purple ceramic polyester sanding disc is built with five functional parts: ceramic abrasive layer, resin-coated bonding layer, polyester film base, hook-and-loop adhesive layer, and 41 dust-removal holes.
Each layer contributes to cutting performance, abrasive grain stability, backing strength, tool attachment, and dust removal during sanding.

Hole Layout
Provides cutting performance for material removal, old paint stripping, putty sanding, rust removal, and surface preparation.
Helps secure ceramic abrasive grains and supports stable sanding performance during coarse sanding operations.
Provides tear resistance, dimensional stability, and flexible backing support for machine sanding.
Allows the sanding disc to attach securely to compatible hook-and-loop sanding pads and supports quick disc replacement.
The 41-hole layout helps improve dust extraction efficiency, reduce abrasive loading, and support cleaner sanding when used with compatible dust collection systems.
Different sandpaper grit ranges are used for different sanding stages, from heavy material removal to surface leveling, paint preparation, and fine sanding.
P80 is not a fine-grit sandpaper. It is primarily used when material needs to be removed from a surface before proceeding to finer sanding steps.
Used for coarse sanding where fast cutting and heavy material removal are required.
Used for coarse sanding, paint stripping, putty shaping, and early-stage surface correction.
Used for surface leveling before priming and preparing the surface after coarse sanding.
Used for primer sanding, paint preparation, and surface refinement before coating.
Used for fine sanding, flaw correction, finish preparation, and sanding stages that require a more refined surface.
