3M 7010328377 Coated Abrasive Disc 3 Inch 40 Grit

Product Description

The 3M 7010328377 is a 3-inch coated abrasive disc engineered for metal grinding and finishing applications where both cut rate and durability matter. It combines 3M ceramic abrasive grain with aluminum oxide in a self-sharpening blend that outlasts standard aluminum oxide discs in stock removal and finishing passes. A heat-resistant resin bond locks the abrasive to a heavy polyester backing rated for medium-pressure use in wet or dry conditions. A grinding aid is integrated into the construction to reduce heat buildup during work on heat-sensitive alloys. HVAC fabricators, metal fabrication shops, and industrial maintenance trades rely on this disc for consistent performance across demanding material types.

This disc is suited for stock removal and surface finishing on stainless steel, nickel alloys, titanium, and other heat-sensitive metals where controlling grinding temperatures is critical. The Roloca attachment system allows fast, secure disc changes without adhesive-backed mounting, making it a practical choice in production environments where downtime between disc changes adds up. It performs in both wet and dry grinding setups, making it adaptable to a range of workstation configurations.

Key Features

• Ceramic and aluminum oxide blend self-sharpens for improved cut rate and durability over standard aluminum oxide
• Roloca attachment system provides secure, tool-free disc mounting and fast removal
• Heavy polyester backing handles medium-pressure applications in wet or dry environments
• Integrated grinding aid reduces heat buildup when working stainless steel, nickel alloys, and titanium
• Heat-resistant resin bond holds abrasive firmly under pressure, heat, and water exposure

Compatibility

Designed for use with compatible Roloca-style disc holders and angle grinder backings that accept 3-inch coated abrasive discs.

Installation Notes

Installation and disc changes should be performed with the grinder fully powered down and unplugged or locked out per standard LOTO procedures. Verify the backing pad is rated for the disc diameter and RPM before mounting. Inspect the disc for damage before each use and discard any disc showing cracks, tears, or delamination. Follow applicable ANSI B11 and OSHA grinding safety guidelines for personal protective equipment and guarding requirements.
