6" PURPLE FILM BACKED NO-HOLE PSA SANDING DISCS WITH TAB - 50 PACK

Benchmark Abrasives 6" purple film backed no-hole PSA sanding discs are designed for high-performance sanding where durability, fast cutting, and a consistent finish matter. The ceramic and zirconia abrasive blend delivers a sharp, efficient cut, while the tear-resistant polyester film backing stays flatter and stronger than conventional paper-backed discs, especially around edges, contours, and detailed surfaces.

Each disc includes a tabbed release liner for quick peel-and-stick mounting to a compatible PSA backing pad. The open-coat construction helps reduce loading, while the film backing provides a more uniform abrasive surface for a consistent scratch pattern from aggressive material removal through very fine surface refinement.

Quantity: 50 discs

PSA backing pad sold separately where applicable.

Use lower grit numbers for faster, more aggressive material removal. Progressively finer grits provide more control and a smoother scratch pattern for blending, finishing, and surface preparation.

Why Choose Purple PSA Discs?

Purple combines a premium ceramic/zirconia abrasive blend with a strong polyester film backing for users who want more durability, more consistent scratch patterns, and a wider finishing range than conventional paper-backed discs.

The PSA attachment gives you a firm, direct connection to the backing pad, while the tabbed release liner makes disc changes fast and clean. It is especially well suited for automotive, fabrication, woodworking, paint-prep, and finishing applications where disc durability and surface consistency matter.

Tips for Better Sanding Performance

• Start with a clean, dry PSA backing pad for the strongest adhesive hold.
• Use the tab to remove the release liner without handling the adhesive surface unnecessarily.
• Center the disc on the backing pad before pressing it firmly into place.
• Keep the sander moving to maintain a uniform scratch pattern.
• Allow the abrasive to do the cutting rather than applying excessive downward pressure.
• Move through progressively finer grits instead of making large grit jumps.
• Take advantage of the durable film backing when sanding edges, contours, and irregular surfaces.
• When wet sanding, use equipment and procedures appropriate for wet applications.
• Replace the disc when cutting performance noticeably decreases or the abrasive becomes excessively loaded.

• Use appropriate eye, hearing, respiratory, and hand protection for the material being sanded.

Built for Better Results Across More Sanding Stages

From aggressive material removal through fine finish preparation, Benchmark Abrasives Purple PSA Discs give you the durability, consistency, and grit range to keep more of the sanding process within one dependable disc family.

For shops, fabricators, woodworkers, painters, and finishers who want fewer failures from torn backing and more control over the final surface, Purple is the higher-performance PSA choice.
