Pre-polishing brush YATO YT-47780, rotary tool accessory, 6 mm shank, max 4500 RPM

YATO YT-47780 is a pre-polishing brush for rotary tools with a 6 mm shank and a maximum rated speed of 4500 RPM. Designed for preliminary surface preparation, this accessory helps remove light burrs, smooth roughness and ready surfaces for finer polishing or finishing. The brush is suitable for use on metal, painted surfaces and soft composite materials in workshop and automotive environments.

Advantages

The brush offers a compact 6 mm shank for straightforward mounting in many rotary tool chucks and collets. Its construction enables consistent contact with the workpiece at speeds up to 4500 RPM, providing uniform pre-polishing without aggressive material removal. The design reduces the time required to prepare parts for subsequent polishing operations and is suitable for repeated workshop use where controlled surface treatment is needed.

Suitable for

• Removing light burrs and flash from metal parts
• Pre-polishing painted surfaces before finishing
• Smoothing soft composite or plastic components
• General surface preparation in automotive repair and metalworking

Key specifications

• Shank diameter: 6 mm
• Maximum rotational speed: 4500 RPM
• Intended use: pre-polishing, light deburring, surface preparation
• Compatible materials: metals, paint coatings, soft composites
• Tool interface: rotary tool accessory

How to use

Fit the brush securely into the rotary tool chuck or collet that accepts a 6 mm shank. Start the tool at low speed to check for runout and balance, then gradually increase up to the recommended maximum of 4500 RPM while maintaining steady control. Apply light, even pressure to avoid aggressive material removal; let the brush do the work. Move the brush across the surface in overlapping passes until the desired pre-polish or deburring is achieved. Inspect the workpiece frequently and stop the tool before changing accessories or making adjustments.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses, gloves and hearing protection. Avoid exceeding the specified maximum speed and ensure the brush is clean and undamaged before use. For painted surfaces, test on an inconspicuous area first to confirm compatibility. Store the accessory in a dry place to prevent contamination and deformation.
