Sanding brush Makita D-73427 Carbon steel 11.5 cm 12500 RPM

The Makita D-73427 sanding brush is a carbon-steel rotary brush intended for surface preparation and light material removal. With a working diameter of 11.5 cm and a rated top speed of 12,500 RPM, this accessory is designed to attach to compatible rotary tools for sanding, deburring, rust removal and surface blending on metal and other hard substrates.

Advantages

This carbon steel construction provides consistent stiffness and wear resistance for repeated use. The 11.5 cm diameter gives a balance between coverage and control, allowing efficient removal of paint, corrosion, or scale from medium-sized areas. The brush is compatible with high-speed rotary tools that support the specified maximum RPM, offering predictable performance when used within recommended speed limits.

Suitable for

• Removing rust and scale from metal surfaces
• Deburring welded seams and cut edges
• Preparing metal for painting or coating
• Surface blending and light sanding on hard materials

Key specifications

• Brush material: carbon steel filaments
• Working diameter: 11.5 cm
• Maximum rotational speed: 12,500 RPM
• Intended tool type: rotary/polishing tools with compatible attachment
• Suitable for use on metal and other hard substrates

How to use

Mount the sanding brush on a compatible rotary tool according to the tool manufacturer’s instructions and ensure the attachment is secure before operation. Verify the tool’s maximum speed and operate at or below 12,500 RPM. Hold the tool with a firm, steady grip and apply light to moderate pressure while moving the brush across the work surface to avoid gouging. Allow the brush filaments to do the work; avoid excessive force and frequent side loading which can reduce brush life. Inspect the workpiece intermittently and stop periodically to check progress and to clear any debris build-up.

Usage recommendations

Wear appropriate personal protective equipment including eye protection, gloves, and respiratory protection when working with metal dust or paint residues. Use in well-ventilated areas and follow the rotary tool manufacturer’s safety guidelines. Match brush size and filament type to the task, and replace the brush when filaments show significant wear or deformation to maintain consistent results.
