Wire cup brush Lessmann Kopbørste Bølget 100 mm M14 RF 0,35 for angle grinders

Lessmann Kopbørste Bølget 100 mm M14 RF 0,35 is a wire cup brush designed for use with angle grinders. The 100 mm diameter and M14 mounting make it compatible with many common grinders, while the wavy wire profile provides an aggressive brushing action for metal surface preparation. This brush is intended for tasks such as rust and paint removal, deburring edges, and cleaning weld seams to prepare surfaces before coating or further processing.

Advantages

The wavy wire design ensures efficient material removal and reduces vibration compared with straight-wire brushes of similar grade. Constructed for stable rotation at grinder speeds, the cup shape maintains good contact with curved and irregular surfaces. The brush offers consistent performance for repeated cleaning and surface preparation jobs, and its dimensions are optimized for a balance between coverage area and access to tighter spots.

Suitable for

• Removing rust and old paint from metal surfaces
• Cleaning and preparing weld seams prior to inspection or painting
• Deburring and edge blending on steel components
• General metal surface finishing and maintenance

Key specifications

• Brush type: wavy wire cup brush
• Diameter: 100 mm
• Mounting thread: M14 compatible with angle grinders
• Wire thickness/profile: RF 0,35 (wavy wire)
• Shape: cup for good surface contact on curved areas

How to use

Secure the brush onto the angle grinder using the M14 thread according to the grinder manufacturer's mounting instructions. Operate the grinder at the recommended speed range and apply light to moderate pressure, allowing the brush to do the work rather than forcing it into the surface. Move the brush steadily across the workpiece to avoid local overheating or excessive material removal. Inspect the brush and workpiece regularly during use to ensure even surface treatment.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves, and hearing protection. For best results on painted surfaces or heavy corrosion, combine the brush with coarse abrasive discs for bulk removal, then finish with finer brushes or abrasives as needed. Store the brush in a dry place away from corrosive environments to maintain wire integrity.
