Sanding brush Makita D-73396 Carbon steel 7.5 cm 12500 RPM

The Makita D-73396 sanding brush is a carbon steel rotary brush with a 7.5 cm diameter designed for surface finishing, rust and paint removal, and light deburring. Built for compatibility with angle grinders and other rotary tools that accept brush-style attachments, this sanding brush runs at up to 12,500 RPM to provide consistent material removal on metal, wood and composite surfaces. The compact diameter and dense carbon steel filaments give balance between aggressiveness and control for medium-duty cleaning and preparation tasks.

Advantages

The carbon steel construction offers durable filament life and strong abrasive action for effective rust, scale and old paint removal. At 7.5 cm diameter the brush provides good access to confined areas while maintaining sufficient coverage for faster work. The rated maximum speed of 12,500 RPM ensures efficient cutting and surface conditioning when used within the tool's specified speed range. The brush design promotes uniform contact with the workpiece for predictable results across repeated operations.

Suitable for

• Removing rust, scale and loose paint from metal surfaces
• Surface preparation before welding or repainting
• Light deburring and edge blending on metal parts
• Cleaning and conditioning small to mid-size wooden surfaces and composites
• Restoration of metal tools, fixtures and hardware

How to use

Secure the sanding brush to a compatible rotary tool or angle grinder according to the tool manufacturer's instructions, ensuring the tool is unplugged or the battery removed during installation. Verify the brush is mounted straight and tightened correctly, then wear appropriate personal protective equipment including eye protection, gloves and a dust mask. Start the tool at low speed and gradually increase to working speed, keeping steady, even pressure and moving the brush across the surface to avoid gouging. Work in controlled passes until the desired finish is achieved, and allow the brush to cool between extended uses.

Usage recommendations

Use the Makita D-73396 sanding brush on clean, dry workpieces and select a compatible tool whose maximum no-load speed matches or exceeds the brush's rated RPM. Avoid excessive pressure and lateral twisting to extend filament life and maintain consistent results. For painted surfaces, test in an inconspicuous area to ensure the brush aggressiveness meets the requirement for the finish. Replace the brush when filaments are worn or damaged to preserve efficiency and safety.
