3M 7100138183 Bristle Disc 7 Inch 36 Grit Ceramic

Product Description

The 3M 7100138183 is a 7-inch ceramic abrasive bristle disc designed for aggressive surface preparation on large work areas. Molded, flexible bristles filled with proprietary ceramic abrasive grain strip paint, rust, weld burns, heavy oxides, adhesives, and other surface contaminants with consistent cutting action from first use to last. The straight-style disc is built for use with compatible right-angle grinders and surface preparation tools common in metal fabrication, industrial maintenance, and facility service work. At 36 grit, it delivers fast material removal without the wire-filament hazard associated with wire cup brushes.

This disc is suited for coating removal, deburring, blending, and cleaning on metal surfaces including steel, aluminum, and other structural materials. The flexible bristle design allows the disc to conform to contours and complex part geometries, making it useful for both flat surfaces and irregular profiles. Typical applications include weld preparation and cleanup, rust and oxide removal, and paint or adhesive stripping across large surface areas in industrial, commercial, and heavy-maintenance environments. Installation and operation require appropriate personal protective equipment including eye and face protection.

Key Features

• Ceramic abrasive grain provides aggressive, consistent cutting throughout the full disc life
• Flexible, abrasive-filled bristles conform to contours and complex part profiles
• Removes paint, rust, weld burns, heavy oxides, adhesives, and surface contaminants
• No wire filaments, reducing the safety risks associated with wire brush breakage
• Requires less operator pressure than wire brushes for effective material removal
• Bristle spacing optimized for high-loading coating removal applications

Compatibility

Designed as an OEM-style abrasive disc for use with right-angle grinders and surface preparation tools that accept a 7-inch straight bristle disc.

Installation Notes

Mounting and operation should be performed by qualified personnel familiar with abrasive disc safety practices. Verify that the tool speed rating meets or exceeds the maximum RPM rating of the disc before mounting. Ensure the work surface is secured and all nearby personnel are clear before operating. Always wear appropriate eye, face, and hand protection during use.
