Norton 66261183823 Psa Disc 400 Grit 6 in Aluminum Oxide 100pk

Product Description

The NORTON 66261183823 is a pressure-sensitive adhesive (PSA) abrasive disc engineered for super fine surface finishing and blending operations. Built on a flexible C-weight paper backing with an aluminum oxide abrasive layer, this 6-inch disc delivers consistent 400-grit cutting action across a broad range of materials. The PSA mount allows for fast, secure attachment to compatible backup pads without mechanical fasteners. Each pack contains 100 discs, making it a practical shop supply for production-level work. Aluminum oxide construction provides a sharp, durable cut that holds up through multiple passes on aluminum, composites, and similar materials.

This disc is suited for finishing and blending tasks on aluminum and composite substrates in both production and job-site environments. The flexible paper backing conforms to mild contours, making it effective on shaped panels and fabricated parts. It is designed for use on random orbital sanders rated for PSA-style disc mounting. The 400-grit super fine classification places it in finish preparation stages, typically following coarser stock removal and preceding final surface treatment or coating application. Automotive body technicians, metal fabricators, and composites shops are the primary installers.

Key Features

• 400-grit aluminum oxide abrasive for super fine blending and finish preparation
• Pressure-sensitive adhesive (PSA) backing for tool-free disc changes on compatible backup pads
• Flexible C-weight paper backing conforms to light contours
• Rated to 15,000 RPM for use on random orbital sanders
• No vacuum holes — suited for solid backup pad configurations
• Pack of 100 discs supports continuous production use

Compatibility

Designed for use on random orbital sanders equipped with PSA-style backup pads accepting 6-inch discs. Rated for aluminum and composite material applications per manufacturer specification.

Installation Notes

Ensure the sander is powered off and unplugged before mounting or removing discs. Align the disc flush with the backup pad surface before pressing firmly to activate the adhesive bond. Verify the sander is rated for the 15,000 RPM maximum speed of this disc before operation. No vacuum hole alignment is required, but confirm the backup pad is clean and free of debris to maintain full adhesive contact.
