Wire Kegel Brush Makita D-39861 100 mm for surface cleaning and rust removal

Makita D-39861 is a 100 mm kegel (cone) wire brush designed as an accessory for power tools, intended for mechanical removal of rust, paint, scale and dirt from metal and other hard surfaces. The conical shape concentrates wire tips for access to weld seams, tight corners and irregular surfaces, enabling surface preparation before painting, coating or welding and finishing after grinding or deburring.

Advantages

The cone-shaped wire cluster and 100 mm diameter provide targeted contact area for efficient material removal while preserving surrounding geometry. Constructed for use with compatible grinders and rotary tools, the brush offers consistent cleaning performance on steel and other robust substrates. Its design facilitates access to narrow joints and crevices where flat brushes cannot reach, improving preparation quality for subsequent treatments.

Suitable for

• Removing rust, scale and old paint from metal surfaces
• Cleaning weld seams and removing welding spatter
• Deburring and edge preparation on metal parts
• Surface preparation prior to painting, coating or welding

Key specifications

• Brush type: kegel (cone) wire brush
• Diameter: 100 mm
• Intended use: surface cleaning, rust and paint removal, deburring
• Compatible with: grinders and rotary tools that accept this brush type
• Application materials: metal and other hard surfaces

How to use

Fit the Makita D-39861 wire kegel brush to a compatible grinder or rotary tool following the tool manufacturer’s instructions and safety procedures. Secure the brush and check for correct mounting and run-out before operation. Operate the tool at recommended speeds, applying steady, moderate pressure while moving the brush across the target area to avoid excessive material removal. Maintain control of the tool and allow the brush to do the work rather than forcing it into the surface. Stop the tool and inspect the workpiece periodically to achieve the desired finish.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves, and respiratory protection when working with metal dust and paint residues. Avoid contact with soft materials and finished surfaces to prevent scratching. Follow the grinder or rotary tool speed limits and replace the brush if wires become excessively worn or damaged.
