3M 7000045624 Ceramic Abrasive Disc 60 Grit 1.5 in

Product Description

The 3M 7000045624 is a coated abrasive disc from the Roloc 777F series, designed for grinding and surface finishing in metal fabrication and industrial maintenance applications. It combines ceramic abrasive grain with aluminum oxide in a blended mineral system that self-sharpens during use, maintaining a consistent cut rate across the disc life. The heavy polyester backing is water-resistant and rated for medium-pressure operation in both wet and dry conditions. At 1.5 inches in diameter and 60 grit, it is suited for stock removal and transitional finishing passes on metals including stainless steel, nickel alloys, and titanium.

This disc is built for use with compatible Roloc quick-change attachment systems, making it a practical choice for angle grinders and die grinders used in production grinding, weld blending, and deburring. The 60-grit specification targets aggressive material removal while the ceramic-aluminum oxide blend provides the durability needed for repetitive passes on heat-sensitive alloys. A grinding aid incorporated into the formulation helps reduce grinding temperatures, which is particularly relevant when working on stainless steel and similar alloys where heat discoloration or metallurgical damage is a concern.

Key Features

• Ceramic and aluminum oxide blended mineral self-sharpens for improved cut rate and durability over standard aluminum oxide discs
• Roloc-style quick-change attachment enables fast, secure disc swaps without tools
• Heavy polyester backing supports medium-pressure applications in wet and dry environments
• Grinding aid reduces heat buildup, protecting heat-sensitive alloys such as stainless steel, nickel alloys, and titanium
• Heat-resistant resin bond maintains abrasive adhesion under sustained pressure and elevated temperatures

Compatibility

Designed for use with Roloc-compatible quick-change disc holders and backup pads on angle grinders and die grinders used in metal fabrication, weld finishing, and surface prep applications.

Installation Notes

Disc installation and removal should be performed with the grinder powered off and unplugged or the air supply disconnected. Ensure the backup pad is rated for the spindle speed of the tool before attaching the disc. Inspect the disc for damage before each use and do not use damaged or delaminated discs. Follow applicable workplace safety standards for abrasive wheel use, including appropriate eye and face protection.
