3M 7000045621 Abrasive Disc 80 Grit Ceramic 1 Inch

Product Description

The 3M 7000045621 is a coated abrasive disc designed for both stock removal and finishing operations in metalworking and fabrication environments. It combines 3M-engineered ceramic abrasive grain with aluminum oxide to deliver a self-sharpening mineral blend that outlasts standard aluminum oxide discs in cut rate and durability. The disc features a heavy, water-resistant polyester backing rated for medium-pressure applications and performs consistently in both wet and dry conditions. A grinding aid is incorporated into the construction to reduce heat buildup, making it suitable for heat-sensitive alloys. Licensed tradespeople and shop professionals working with stainless steel, nickel alloys, and titanium will find this disc well-suited to precision grinding tasks.

This disc is built for use in industrial and fabrication settings where consistent cut rate and attachment reliability matter. The Roloca attachment system provides secure disc mounting and efficient removal, reducing changeover time during production runs. It is appropriate for applications ranging from general metal stock removal to surface finishing passes, and its wet and dry capability supports varied shop environments where coolant or water-based processes are in use.

Key Features

• Ceramic and aluminum oxide blend self-sharpens during use for improved cut rate and durability over aluminum oxide alone
• Roloca attachment system provides secure, efficient disc mounting and fast removal
• Heavy polyester backing supports medium-pressure grinding in wet and dry conditions
• Grinding aid reduces heat generation, protecting heat-sensitive alloys such as stainless steel, nickel alloys, and titanium
• Heat-resistant resin bond holds abrasive to backing under pressure, heat, and water exposure
• 80 grit rating suits general stock removal and intermediate finishing

Compatibility

Designed for use with compatible Roloca-style disc tools and backing pads that accept 1 inch diameter coated abrasive discs in medium-pressure grinding and finishing applications.

Installation Notes

Installation is performed by qualified grinding and fabrication professionals familiar with abrasive disc handling. Ensure the backing pad and tool are powered off and fully stopped before mounting or removing the disc. Inspect the backing pad for wear or damage before attaching a new disc. Follow applicable ANSI B11 and shop safety standards for abrasive tool operation, including appropriate RPM ratings and personal protective equipment.
