Wire Cup Brush Makita P-04488 65 mm M14 for steel, paint and rust removal

Wire Cup Brush Makita P-04488 is a 65 mm diameter cup brush with an M14 thread, designed to be mounted on angle grinders and similar rotary tools with an M14 arbor. The brush is intended for mechanical cleaning of steel surfaces and for preparing metal before painting or welding. Its compact diameter and cup shape provide concentrated brushing action for efficient removal of paint, rust and other surface contaminants on workpieces and structural elements.

Advantages

The brush delivers stable rotational balance and consistent wire engagement with the surface, enabling controlled material removal and uniform finish. Its cup form concentrates brushing force on a defined area, which improves access to curved and uneven surfaces compared with flat discs. The M14 threaded connection ensures compatibility with a wide range of grinders and simplifies mounting and replacement.

Suitable for

• Removing paint and coatings from steel parts
• Rust and scale removal on metal surfaces
• Surface preparation before welding or repainting
• Cleaning weld seams, joints and small structural elements

Key specifications

• Cup diameter: 65 mm
• Thread type: M14 (for tool arbor)
• Brush material: steel wire suitable for ferrous metals
• Shape: cup brush for concentrated brushing action
• Typical application speed: compatible with standard grinder speeds (observe tool limits)

How to use

Fit the wire cup brush onto the grinder spindle using the M14 thread and secure it according to the grinder manufacturer’s instructions. Run the grinder at a speed appropriate for the brush and the workpiece, and apply steady, controlled pressure while moving the brush across the surface. Avoid excessive force or dwell in one spot to prevent damage to the base material. Use with both pushing and sweeping motions to achieve an even result on flat and contoured areas.

Usage recommendations

Use appropriate personal protective equipment: eye and face protection, gloves and respiratory protection when working with paint and rust. Ensure the grinder’s guard is in place and follow the tool manufacturer’s maximum speed rating. Inspect the brush before use for wire breakage or deformation and replace if worn or damaged.
