Wire cup brush Polax 75 mm M14 shank, brass bristles

Polax wire cup brush, 75 mm diameter with an M14 threaded shank, fitted with brass bristles for controlled surface treatment. Designed for use with angle grinders that accept an M14 arbor, this cup brush is intended for cleaning, removing rust and paint, deburring and light polishing on metal and mixed materials. The compact 75 mm cup allows access to confined areas while providing a consistent finish on workpieces during renovation and metalworking operations.

Advantages

The brass bristles provide effective abrasion while reducing the risk of sparking and scratching compared with harder steel wires. The cup shape ensures uniform contact with flat or slightly contoured surfaces and helps maintain balance at typical operating speeds of handheld grinders. Threaded M14 attachment offers wide compatibility with angle grinders that use a standard M14 arbor, enabling quick fitting and secure mounting during operation.

Suitable for

• Surface cleaning of metal parts
• Removal of rust and flaking paint
• Deburring edges and weld seams
• Light polishing and finishing of metal surfaces
• Preparation of small areas before painting or coating

Key specifications

• Brush shape: cup
• Typical applications: surface cleaning, rust and paint removal, deburring, light polishing

How to use

Mount the wire cup brush securely on an angle grinder with a compatible M14 arbor following the tool manufacturer's instructions. Before full operation, run the grinder at low speed to check for balance and secure attachment. Hold the grinder with both hands, apply light to moderate pressure, and move the brush steadily across the surface to remove rust, paint or burrs. Avoid excessive force and do not jam the brush, as this can deform the bristles and reduce effectiveness. After use, allow the brush to stop fully before setting the tool down and inspect the bristles for wear or damage.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and hearing protection. Select the brass-bristled cup brush where reduced surface marking is desirable compared with harder wire brushes. Replace the brush when bristles are worn or when performance declines. Do not use the brush at speeds exceeding the maximum RPM rating of the brush or the grinder.
