3M 7100288135 Hook Loop Sanding Disc 6 in 220 Grit

Product Description

The 3M 7100288135 is a 6-inch hook-and-loop sanding disc engineered for orbital and random-orbit sanders used in surface preparation and finishing work. Built on a mesh backing with precision shaped ceramic abrasive, this disc delivers consistent cut rates and extended service life compared to conventional aluminum oxide or silicon carbide discs. It runs at up to 12,000 RPM and is rated at 220 grit, placing it in the fine finishing range. The purple-colored disc belongs to the 3M 710W series. It is used by finishing contractors, cabinet installers, auto body technicians, and skilled trades workers requiring a reliable hook-and-loop interface for quick disc changes during sanding operations.

This disc is suited for fine finish sanding on wood, painted surfaces, composites, and similar substrates where surface smoothness and scratch pattern consistency matter. The mesh backing allows dust to pass through the abrasive layer itself, improving debris clearance even on sanders without dedicated vacuum ports. This makes it a practical choice in dry sanding applications where clogging and heat buildup are concerns. The hook-and-loop attachment system is compatible with standard 6-inch hook-and-loop backup pads commonly used on random orbital sanders in shop and field settings.

Key Features

• Precision shaped ceramic abrasive for consistent cut and extended disc life
• Mesh backing improves dust clearance without requiring vacuum holes in the disc
• 220 grit rating for fine surface finishing and scratch refinement
• Hook-and-loop attachment for fast, tool-free disc changes
• 12,000 RPM maximum speed rating suits standard random orbital sanders
• Part of the 3M 710W series for consistent abrasive performance across the product line

Compatibility

Designed for use with 6-inch hook-and-loop backup pads on random orbital and orbital finishing sanders. No vacuum holes are included on this disc; confirm compatibility with your sander and backup pad configuration before use.

Installation Notes

This disc is installed by pressing the loop side firmly onto a hook-style backup pad mounted on an orbital sander. Ensure the sander is powered off and disconnected before changing discs. Do not exceed the 12,000 RPM maximum speed rating. Inspect the backup pad hook surface regularly for wear, as a degraded pad face reduces disc retention and can cause disc separation during operation.
