3M 7000000555 Abrasive Disc 80 Grit 3 Inch Ceramic

Product Description

The 3M 7000000555 is a coated abrasive disc engineered for trade and industrial grinding and finishing work. It combines 3M ceramic abrasive grain with aluminum oxide in a blend that self-sharpens during use, maintaining a consistent cut-rate longer than straight aluminum oxide discs. At 3 inches in diameter and 80 grit, it handles both stock removal and surface finishing on a single platform. A heat-resistant resin bonds the abrasive to a heavy polyester backing rated for medium-pressure wet and dry applications. An integrated grinding aid manages heat buildup, making the disc suitable for heat-sensitive alloys including stainless steel, nickel alloys, and titanium.

This disc is suited for metal fabrication, weld blending, and surface preparation in both shop and field environments. The 3-inch format fits compact angle grinders and inline grinders common in tight spaces on structural steel, pipe, and sheet metal work. The Roloca attachment system allows fast, secure disc changes without tools, reducing downtime during production runs. Both wet and dry grinding operations are supported by the water-resistant polyester backing.

Key Features

• Ceramic and aluminum oxide blend self-sharpens for improved durability and cut-rate over straight aluminum oxide
• Roloca attachment system provides secure, tool-free disc mounting and removal
• Heavy polyester backing is water-resistant and rated for medium-pressure wet and dry applications
• Grinding aid reduces heat buildup for use on stainless steel, nickel alloys, and titanium
• Heat-resistant resin bonding maintains abrasive integrity under pressure, heat, and moisture
• 80 grit is suitable for both stock removal and intermediate finishing passes

Compatibility

Designed for use with 3-inch Roloca-compatible grinder backing pads in medium-pressure grinding and finishing applications on metal substrates.

Installation Notes

Install and remove the disc using the Roloca attachment system on a compatible 3-inch backing pad. Inspect the disc for damage before each use and replace if torn, cracked, or glazed. Power down and disconnect the grinder before mounting or removing the disc. Use appropriate PPE including eye protection and gloves when operating abrasive grinding equipment.
