3M 7000045625 Abrasive Disc 80 Grit Ceramic 1.5 in

Product Description

The 3M 7000045625 is a coated abrasive disc designed for stock removal and surface finishing in demanding trade and industrial applications. It combines 3M ceramic abrasive grain with aluminum oxide to deliver a self-sharpening mineral blend that maintains a consistent cut-rate over the life of the disc. The disc measures 1.5 inches in diameter and cuts at 80 grit, making it suitable for medium-pressure grinding and finishing on metals and other materials. A heat-resistant resin bonding system secures the abrasive to the polyester backing, supporting performance under pressure, heat, and moisture exposure.

This disc is suited for metal fabrication, maintenance grinding, and surface preparation work in both wet and dry conditions. The heavy polyester backing holds up to medium-pressure applications without delaminating or losing cutting efficiency. Its grinding aid helps reduce heat buildup during grinding, making it appropriate for heat-sensitive alloys including stainless steel, nickel alloys, and titanium. Licensed tradespeople in fabrication shops, maintenance facilities, and manufacturing environments are the primary installers and users.

Key Features

• Ceramic and aluminum oxide blend self-sharpens for improved durability and cut-rate over aluminum oxide alone
• 80 grit rating suitable for medium stock removal and transitional finishing passes
• Heavy, water-resistant polyester backing supports both wet and dry applications
• Grinding aid reduces heat buildup during processing of heat-sensitive alloys such as stainless steel, nickel alloys, and titanium
• Heat-resistant resin bond holds abrasive securely under pressure and elevated temperatures
• Roloca attachment system enables fast, secure disc changes

Compatibility

Designed as a coated abrasive disc replacement for use with compatible 1.5-inch Roloca-style disc holders and grinders accepting that attachment format.

Installation Notes

Mounting and removal should be performed with the tool powered off and unplugged or locked out per applicable lockout-tagout procedures. Confirm the grinder spindle speed rating meets or exceeds the maximum rated speed of the disc before use. Inspect the disc for damage before each use and replace if cracking, fraying, or delamination is present. This consumable is typically installed and changed by machinists, fabricators, or maintenance technicians following the grinder manufacturer guidelines.
