3M 7010308402 Psa Cloth Disc 348D 30 Inch 80 Grit Ao

Product Description

The 3M 7010308402 is the 348D PSA Cloth Disc, a heavy-duty abrasive sanding disc built for aggressive material removal on large-surface applications. It features a pressure-sensitive adhesive backing that bonds securely to a backup pad or steel platen, then releases cleanly for fast disc changes. The aluminum oxide abrasive delivers rapid cut rates and extended service life across a wide range of substrate types. An X-weight cloth backing resists tearing and edge wear under demanding conditions, and a resin bond system shields the disc from heat buildup to further extend disc life.

This disc is suited for high-production grinding, blending, and finishing operations where a large-diameter abrasive is required. The 30-inch diameter and 80-grit cut make it a practical choice for wide-surface stock removal on metal, wood, composites, and similar materials. It supports both wet and dry sanding environments, giving fabricators and finishing shops the flexibility to use it across different process setups. Typical installers include metalworking fabricators, industrial finishers, and woodworking production shops.

Key Features

• Pressure-sensitive adhesive backing bonds to backup pads or steel platens and releases cleanly for quick replacement
• X-weight durable cloth backing resists tearing and edge wear in aggressive applications
• Aluminum oxide abrasive provides fast cut rates and long service life on a broad range of surfaces
• Resin bond construction reduces heat damage and extends overall disc life
• Compatible with both wet and dry sanding applications

Compatibility

Designed for use with large-diameter backup pads or steel platens that accept 30-inch PSA-style sanding discs in industrial and production finishing equipment.

Installation Notes

Clean the backup pad or steel platen surface before applying the disc to ensure full adhesive contact. Press the disc firmly and evenly from center to edge to eliminate air pockets. When removing the disc, peel back slowly at a low angle to protect the platen surface. Always power down and lock out the machine before mounting or removing any abrasive disc.
