Nylon Brush Makita P-04438 K80 — surface preparation brush, K80 abrasive

Makita Nylon Brush P-04438 K80 is a surface preparation brush with K80-grade abrasive nylon filaments designed for use with compatible rotary power tools. The brush provides controlled abrasion for cleaning, deburring and removing coatings, rust and scale from metal and other durable surfaces. It is intended for workshop and jobsite use where consistent surface preparation is required prior to painting, coating or further finishing.

Advantages

The brush combines resilient nylon filaments with embedded K80 abrasive grains to deliver uniform material removal while maintaining filament flexibility and durability. Its construction reduces the risk of aggressive scratching compared with wire brushes, while still offering effective cleaning and light surface profiling. The design supports steady performance over repeated tasks and is suitable for use on irregular surfaces due to the conforming action of the filaments.

Suitable for

• Cleaning rust and scale from metal components
• Removing paint, coatings and adhesives from durable surfaces
• Deburring and descaling machined parts
• Surface preparation before painting, powder coating or sealing
• General workshop and maintenance cleaning tasks

Key specifications

• Abrasive grit: K80 (medium-coarse) embedded in nylon filaments
• Filament material: nylon with abrasive particles
• Intended use: surface cleaning, deburring, coating removal
• Compatible tool type: rotary or angle grinders and other compatible power tools designed for brush attachments
• Performance characteristics: consistent abrasion, flexible filaments for irregular profiles

How to use

Fit the nylon brush to a compatible power tool following the tool manufacturer's mounting and safety instructions. Start the tool at low speed and make an initial test pass on an inconspicuous area to verify the effect. Apply even, moderate pressure and move the brush across the surface in smooth passes; avoid excessive force that can overheat the workpiece or prematurely wear the filaments. Maintain steady tool speed appropriate for the brush and material being worked on, and periodically inspect the brush for wear and clogging.

Recommendations

Use appropriate personal protective equipment (eye protection, gloves, respirator if dust is present) and ensure the workpiece is secured. For painted or coated surfaces, test for underlying materials and hazardous coatings before aggressive cleaning. Replace the brush when filaments are significantly worn or abrasive performance declines to maintain consistent results.
