3M 7100032844 Abrasive Disc Roll 5 Inch P500 Grit

Product Description

The 3M 7100032844 is a Stikit film disc roll designed for fine sanding applications in finishing and surface prep work. Built on a durable, tear-resistant film backing with aluminum oxide abrasive grain, this roll delivers a close-tolerance, consistent finish at P500 grit. The open coat construction reduces loading and keeps the disc cutting aggressively through the work cycle. The pressure-sensitive Stikit adhesive backing attaches and releases quickly from compatible random orbital and finishing sanders. Trade finishers, body shop techs, and fabricators working with plastics, gel coats, and polyurethane solid surfaces will find this roll suited to production sanding workflows.

This disc roll is intended for fine finishing passes on plastics, gel coats, and polyurethane solid surface substrates. The 5 inch diameter and P500 grit make it appropriate for final surface refinement before topcoat or inspection. The roll format eliminates individual disc liners, allowing faster disc changes on the tool and reducing handling time during production runs. Minimum order quantity is 4 rolls per purchase.

Key Features

• Aluminum oxide abrasive grain delivers fast cut and extended service life across a range of surface materials
• Tear-resistant film backing maintains dimensional stability and supports a consistent, close-tolerance finish
• Open coat construction minimizes loading on fine finishing passes
• Stikit pressure-sensitive adhesive backing allows rapid disc application and clean removal from the backup pad
• Roll format removes the need to peel individual disc liners, improving throughput in production environments

Compatibility

Designed for use with 5 inch Stikit-compatible backup pads on random orbital and finishing sanders used in plastics fabrication, fiberglass, gel coat, and polyurethane solid surface finishing work.

Installation Notes

This product is installed by pressing the disc firmly onto a clean, dry Stikit-compatible backup pad. Ensure the backup pad surface is free of debris before attaching a new disc to maintain full adhesive contact. Disengage the sander from power before changing discs. Inspect the film backing for tears or edge damage before each use and discard damaged discs to avoid uneven finish results.
