Wire Cup Brush Aptel M14 65x18 mm steel, crimped, for angle grinders

The Aptel wire cup brush with M14 thread, 65x18 mm, is a steel crimped brush designed for mounting on angle grinders. It provides medium-aggressive brushing action for surface preparation tasks including rust and paint removal, deburring, scale and weld cleaning. The compact cup shape and steel wire filaments make it suitable for targeted work on metal surfaces where controlled material removal and surface conditioning are required.

Advantages

This steel crimped wire cup brush offers a balance between aggressiveness and control, delivering efficient removal of corrosion, paint and welding residues while preserving the underlying geometry of workpieces. The M14 thread ensures secure and simple attachment to most common angle grinders, and the compact 65x18 mm size allows access to tighter areas compared with larger cup brushes. The crimped wire construction reduces vibration and provides consistent brushing performance over the brush life.

Suitable for

• Removing rust and old paint from steel parts
• Deburring edges and cleaning weld seams
• Scale removal from metal surfaces before painting or coating
• General metal surface preparation in fabrication and repair work

Key specifications

• Brush shape: cup
• Filament material: steel wire (crimped)
• Mounting: M14 threaded arbor
• Overall dimensions: 65 mm diameter × 18 mm height
• Intended tool: angle grinder
• Aggressiveness: medium (surface conditioning and material removal)

How to use

Fit the wire cup brush onto an angle grinder by screwing the M14 thread securely onto the grinder’s arbor according to the tool manufacturer’s instructions. Use appropriate rotational speed for the tool and the workpiece material; avoid exceeding the maximum safe speed rated for the brush as specified by the angle grinder and brush supplier. Hold the grinder firmly, apply light to moderate pressure, and move the brush steadily across the surface to achieve uniform cleaning or deburring. Allow the brush to do the work—excessive pressure shortens filament life and can damage the workpiece.

Usage recommendations

Always wear suitable personal protective equipment: eye protection, gloves, and hearing protection. Work in a well-ventilated area and secure small workpieces to prevent movement. Inspect the brush before use for damaged filaments or a loose mounting; do not use if the brush shows signs of excessive wear or damage. For painted or coated surfaces, test a small area first to check the brushing effect and avoid unintended material removal.
