3M 7100050503 Wetordry Abrasive Disc 240 Grit 8 Inches

Product Description

The 3M 7100050503 is a silicon carbide Wetordry abrasive disc designed for wet or dry sanding applications. Built on a C-weight paper backing, this 8-inch disc delivers consistent cut and finish on a range of surfaces. The 240-grit rating makes it well-suited for fine material removal, surface prep, and finish sanding where control and surface quality matter. Trades and finishing professionals choose silicon carbide abrasives for their sharp, friable grain structure, which cuts cleanly and resists glazing on hard materials.

This disc is used in bodywork, metal finishing, composite surface preparation, and similar trade applications where both wet and dry sanding methods are employed. The C-weight paper backing provides a balance of flexibility and durability, making it appropriate for flat and low-contour surfaces. Wet sanding with this disc helps reduce heat buildup and swarf loading, extending usable disc life in production or service environments.

Key Features

• Silicon carbide abrasive grain for sharp, consistent cut on hard surfaces
• 240 grit for fine material removal and surface finishing
• 8-inch diameter with no-hole (NH) center for use with appropriate backing pads
• C-weight paper backing balances flexibility and tear resistance
• Runs wet or dry for versatile application across service environments

Compatibility

Designed as an OEM-style replacement abrasive disc for use with standard 8-inch backing pads compatible with no-hole (NH) disc configurations.

Installation Notes

This disc is installed by hand onto a compatible backing pad sized for 8-inch abrasive discs. Ensure the backing pad surface is clean and free of debris before attaching the disc to maintain even contact. When sanding wet, follow all applicable shop safety practices for slippery surfaces and abrasive slurry disposal. Inspect the disc for tears or uneven wear before each use and replace as needed.
