3M 7000120352 Abrasive Disc P120 Grit 1.5 Inch Ceramic

Product Description

The 3M 7000120352 is a coated abrasive disc engineered for trade and industrial applications requiring both aggressive stock removal and controlled finishing. It uses a blend of 3M ceramic grain and aluminum oxide that self-sharpens during use, maintaining a consistent cut-rate longer than standard aluminum oxide discs. The heavy polyester backing is water-resistant and rated for medium-pressure applications in wet or dry conditions. A built-in grinding aid actively reduces heat buildup at the contact zone, making this disc appropriate for heat-sensitive alloys including stainless steel, nickel alloys, and titanium.

This disc is suited for metal fabrication, weld blending, and surface conditioning tasks where cut consistency and backing durability matter. The 3M Roloc attachment system allows fast, tool-free disc changes, which reduces downtime on repetitive grinding or finishing operations. At 1.5 inches in diameter with P120 grit, it fits compact right-angle die grinders and is appropriate for tight-access areas and detail work on ferrous and non-ferrous metals. Licensed tradespeople and fabricators working to production tolerances will find the predictable cut-rate useful for maintaining surface finish specifications.

Key Features

• Ceramic and aluminum oxide blend self-sharpens for improved cut-rate and durability over aluminum oxide alone
• 3M Roloc attachment system provides secure, tool-free disc mounting and removal
• Heavy water-resistant polyester backing supports medium-pressure wet and dry use
• Grinding aid reduces heat at the contact zone for safe use on stainless steel, nickel alloys, and titanium
• Heat-resistant resin bond holds abrasive grain firmly under pressure, heat, and moisture

Compatibility

Designed for use with 3M Roloc compatible mandrels and right-angle die grinders accepting 1.5-inch quick-change abrasive discs.

Installation Notes

Mount only on a Roloc-compatible mandrel rated for the disc diameter and operating RPM. Verify the grinder speed does not exceed the maximum rated RPM marked on the disc or packaging before use. Eye protection, hearing protection, and appropriate gloves are standard PPE for grinding operations. Inspect the disc for damage before each use and discard any disc that shows tearing, delamination, or unusual wear.
