Abrasive bristle disc 3M 07525, 50.8 mm diameter, grit K80, Scotch-Brite

Abrasive bristle disc 3M 07525 is a Scotch‑Brite surface conditioning accessory with a 50.8 mm diameter and K80 grit formulated for controlled material removal on metals and composite substrates. The disc's flexible bristle construction conforms to contours and edges, delivering consistent deburring, blending and finishing in small or detailed areas. Designed for use with compatible rotary tools, the bristle disc reduces the risk of gouging associated with rigid wheels while maintaining effective stock removal and a uniform surface texture.

Advantages

The flexible abrasive bristles provide uniform contact across curved and irregular surfaces, improving consistency of finish without aggressive cutting. K80 abrasive grains balance material removal and surface refinement, making the disc suitable for removing burrs, light oxidation and paint feathering. The small 50.8 mm diameter allows access to tight spaces and precision work while the open-bristle design minimizes loading and heat buildup during operation.

Suitable for

• Deburring and edge blending on steel, stainless steel and aluminum
• Surface conditioning and light rust or oxidation removal
• Feathering paint edges and preparing small areas for refinishing
• Finishing contours and recessed or detailed features

Key specifications

• Disc diameter: 50.8 mm
• Abrasive grit: K80
• Construction: flexible abrasive bristles (Scotch‑Brite style)
• Intended substrates: ferrous metals, non-ferrous metals and composites
• Tool compatibility: designed for use with compatible rotary tools and small angle drivers

How to use

Mount the abrasive bristle disc onto a compatible rotary tool following the tool manufacturer's instructions and ensure secure attachment before use. Operate the tool at recommended speeds for small-diameter bristle discs; apply light, consistent pressure and allow the flexible bristles to conform to the workpiece rather than forcing aggressive cuts. Move the disc steadily across the work area to achieve even deburring or blending, and pause periodically to inspect the surface and avoid excessive material removal.

Usage recommendations

Use appropriate personal protective equipment, including eye protection, gloves and respiratory protection when working with metal particulates. For best results, start with moderate speed and light pressure, testing on a scrap area to confirm finish and material removal rate before proceeding to the main workpiece.
