3M 7000000759 Scotch-brite Bristle Disc 3/4 in 400 Grit

Product Description

The 3M 7000000759 Scotch-Brite Radial Bristle Disc is a flexible abrasive disc designed for surface preparation, coating removal, deburring, and finishing on metal and other hard surfaces. The disc uses ceramic abrasive grain molded directly into flexible bristles, delivering consistent cutting action from first use to last. At 3/4 inch in diameter and 400 grit, it is suited for fine surface conditioning, blending, and light material removal in tight spaces or on contoured workpieces. No wire filaments are present, reducing the risk of wire fragment contamination. Metalworkers, fabricators, and maintenance technicians commonly use this disc with rotary tools and die grinders.

This disc is used in industrial and commercial fabrication environments where surface prep work demands consistent finish quality. Typical applications include removing weld burns, rust, heavy oxides, paint, adhesives, and other surface contaminants. The curved, flexible bristle design allows the disc to conform to irregular and complex geometries, making it effective on parts where flat abrasive tools lose contact. It is commonly used in metal finishing, maintenance and repair operations, and light manufacturing settings where controlled material removal is required.

Key Features

• Ceramic abrasive grain molded into flexible bristles delivers consistent cut rate throughout disc life
• Bristles conform to contours and complex part geometries, maintaining surface contact better than rigid abrasives
• Contains no wire filaments, eliminating the risk of embedded wire fragments in finished surfaces
• Bristle spacing is optimized for coating removal and high-loading surface contaminants
• Curved disc profile provides more surface contact than flat wire brushes on contoured workpieces
• Effective for stripping, deburring, blending, finishing, polishing, and cleaning in a single tool

Compatibility

Designed as an OEM-style replacement or direct-fit abrasive disc for rotary tools and die grinders accepting 3/4 inch diameter radial bristle disc attachments.

Installation Notes

Installation and operation should be performed by trained metalworkers or maintenance technicians familiar with rotary abrasive tooling. Verify that the rotary tool or die grinder RPM rating is compatible with the disc before mounting. Always wear appropriate PPE including eye protection and gloves when operating abrasive discs. Inspect the disc for damage before each use and do not use a damaged or deformed disc.
