Sanding brush Makita D-73330 8 cm 12500 RPM

The Makita D-73330 sanding brush is a rotary-tool accessory with an 8 cm diameter and a thickness of 0.5 mm, designed for sanding and light grinding tasks. Rated for a maximum rotational speed of 12,500 RPM, this single-pack brush is intended for surface preparation, smoothing edges, and removing small amounts of material from wood, metal, and composites. The construction is compatible with common rotary tool collets and provides consistent contact with the treated surface for uniform finish.

Advantages

The sanding brush offers a compact 8 cm working diameter that balances coverage and control, while the 0.5 mm thickness ensures flexibility for following contours. Its 12,500 RPM maximum speed allows efficient material removal without excessive vibration when used within recommended limits. The single-pack format makes it easy to replace spent brushes and keeps spares on hand for project continuity.

Suitable for

• Removing paint, rust, and corrosion from small areas
• Sanding and finishing wooden surfaces and edges
• Deburring and smoothing metal parts
• Preparing composite or plastic surfaces prior to bonding or painting
• Detail work with rotary tools in hobby and light professional applications

Key specifications

• Working diameter: 8 cm
• Thickness: 0.5 mm
• Maximum rotational speed: 12,500 RPM
• Pack quantity: single brush
• Compatible with standard rotary tool collets and mandrels

How to use

Mount the sanding brush securely in the rotary tool collet or onto a compatible mandrel, ensuring correct seating and balance before operation. Start the tool at a low speed to confirm stable rotation, then increase speed up to but not exceeding the specified maximum of 12,500 RPM based on the material and task. Apply light, even pressure and move the brush across the surface in steady strokes to achieve a uniform finish; avoid forcing the brush into the workpiece to minimize wear and prevent uneven results. Replace the brush when abrasive performance decreases or if the brush shows signs of damage.

Usage recommendations

Use appropriate personal protective equipment such as eye protection, dust mask, and gloves. For best results, match brush speed and pressure to the substrate: lower speeds for delicate materials and higher speeds within the rated limit for tougher sanding tasks. Keep the work area well ventilated and secure the workpiece before starting. Store the brush in a dry place to preserve abrasive qualities.
