Rotary Bristle Brush 3M Roloc 76 mm K80 Yellow for Surface Cleaning and Finishing

The 3M Roloc Rotary Bristle Brush 76 mm K80 in yellow is a compact abrasive tool designed for use with Roloc quick-change systems. The brush combines flexible, abrasive-filled nylon bristles with a 76 mm diameter to deliver controlled material removal, surface cleaning, light deburring and paint or coating scuffing. Constructed for consistent contact with irregular shapes and contours, it helps prepare metal and other solid substrates for subsequent finishing operations while maintaining workpiece profiles.

Advantages

This 3M Roloc bristle brush offers conformable abrasive action that adapts to contours and edges, reducing the risk of gouging while ensuring even surface treatment. The K80 abrasive grade balances cutting speed and surface finish for effective paint and rust removal as well as light deburring. Its Roloc-compatible mounting enables fast, secure tool changes to increase workflow efficiency in workshop and maintenance environments. The compact 76 mm diameter provides access to confined areas where larger tools cannot reach.

Suitable for

• Surface cleaning and light paint removal on metal parts
• Light deburring and edge blending after machining or cutting
• Preparation of substrates before priming, painting or coating
• Cleaning weld seams and removing oxidation or scale

Key specifications

• Diameter: 76 mm
• Abrasive grit: K80 (medium coarse)
• Bristle material: abrasive-filled nylon
• Mounting system: Roloc quick-change compatible
• Intended use: rotary surface conditioning for metal and solid substrates

How to use

Attach the brush to a Roloc-compatible rotary tool according to the tool manufacturer’s instructions, ensuring a secure fit before operation. Operate at the recommended speed range for Roloc bristle brushes and apply light to moderate pressure to allow the bristles to conform to the work surface; excessive pressure may reduce bristle life and degrade finish quality. Move the brush steadily across the workpiece, maintaining consistent contact and overlapping passes for uniform results. Periodically inspect the brush for wear and replace when bristles are excessively worn or performance declines.

Recommendations

Use appropriate personal protective equipment including eye and respiratory protection, gloves and hearing protection when operating rotary tools. Test on a sample area before full application to confirm compatibility with the substrate and desired finish. Store in a clean, dry place away from solvents and high temperatures to preserve bristle integrity.
