Sanding brush Makita D-73449 Carbon steel 10 cm 12500 RPM

The Makita D-73449 sanding brush is a carbon steel wheel designed for grinding and surface preparation. With a 10 cm diameter and 0.3 mm wire thickness, this brush is intended for use on angle grinders and similar rotary tools to remove rust, paint, burrs and to create a uniform matte finish. Its rated maximum speed of 12,500 RPM matches common rotary tool operating ranges and enables efficient material removal while maintaining consistent brush profile.

Advantages

The carbon steel filaments provide aggressive cleaning and long wear life compared with softer materials, while the 0.3 mm thickness balances stiffness and flexibility for controlled abrasion. The compact 10 cm diameter offers access to confined areas and steady handling during rotational work. Compatibility with high-speed tools up to 12,500 RPM ensures that the brush keeps its shape under typical working loads and delivers repeatable results.

Suitable for

• Removing rust and scale from metal surfaces
• Stripping paint and coatings
• Deburring welded joints and edges
• Surface preparation before painting or coating
• Matting or roughening surfaces for adhesion

Key specifications

• Brush material: carbon steel filaments
• Diameter: 100 mm
• Filament thickness: 0.3 mm
• Maximum rotational speed: 12,500 RPM
• Suitable for use with angle grinders and compatible rotary tools

How to use

Mount the sanding brush securely to a compatible tool according to the tool manufacturer’s instructions, ensuring that the spindle size and mounting method match. Inspect the brush for damage before each use and wear appropriate personal protective equipment such as eye protection, gloves and a dust mask. Start the tool at low speed to check balance, then increase to working speed as permitted, keeping steady, controlled passes across the workpiece. Avoid excessive side pressure; allow the brush filaments to do the work to reduce premature wear and maintain an even finish.

Usage recommendations

For optimal performance, use the brush on clean, dry surfaces and replace it when filaments become worn or deformed. Match brush speed to the material and maintain consistent feed to achieve uniform results. Store in a dry environment to prevent filament corrosion.
