3M 7000119207 Cubitron Ii 987C Fiber Disc 60 Grit 4.5 in

Product Description

The 3M 7000119207 is a Cubitron II 987C coated fiber disc engineered for medium to heavy-duty grinding, weld grinding, and beveling applications. It uses 3M Precision-Shaped Grain, a ceramic abrasive mineral that maintains sharp cutting points throughout the disc life. This design delivers a higher cut rate with less applied pressure compared to conventional fiber discs. The stiff fiber backing paired with a strong resin bond resists tearing under aggressive load conditions. A built-in grinding aid reduces heat buildup at the work surface, making this disc suitable for heat-sensitive alloys. Fabricators, welders, and metal finishing technicians are the primary installers of this product.

This disc is suited for robotic grinding setups, pressure-assisted angle grinder applications, and manual weld removal on structural and sheet metal. The 4.5-inch diameter and 60-grit specification make it a practical choice for aggressive stock removal and weld bead grinding where surface prep speed matters. The coated construction and fiber substrate handle high grinding pressures without delaminating, reducing the frequency of disc changes and associated downtime on production lines or job sites.

Key Features

• 3M Precision-Shaped Grain maintains sharp cutting points for fast stock removal with reduced pressure
• Runs cooler than conventional abrasive discs, extending disc life on heat-sensitive alloys
• Stiff fiber backing and strong resin bond resist tearing in high-pressure weld grinding and beveling
• Built-in grinding aid minimizes heat generation at the work surface
• Reduces disc changeouts in robotic and pressure-assisted grinding applications
• Higher cut rate and longer service life per disc compared to standard fiber discs

Compatibility

Designed for use with standard 4.5-inch angle grinders and disc holders compatible with coated fiber discs in medium to heavy-duty metal grinding and finishing applications.

Installation Notes

Installation and disc changes should be performed by qualified metalworking or fabrication personnel following grinder manufacturer guidelines and applicable ANSI B11 safety standards. Ensure the grinder is powered off and unplugged before mounting or removing any abrasive disc. Confirm the disc backing hub and arbor size match before use, and inspect the disc for damage prior to each application. Do not exceed the maximum RPM rating marked on the disc or grinder guard.
