Wire cup brush Polax M14 100 mm with brass bristles for angle grinders

Polax wire cup brush with M14 thread and 100 mm diameter, equipped with brass bristles, is intended for use with angle grinders for cleaning and surface preparation of metal parts. The brush removes rust, old paint, scale and light welding spatter while producing less surface scratching than steel-wire brushes. Its compact cup shape and balanced construction ensure stable rotation and consistent contact with the workpiece.

Advantages

The brass bristles provide effective material removal while minimizing the risk of deep scratches on softer metals and finished surfaces. The M14 threaded mount allows quick and secure attachment to most angle grinders that accept M14 fittings. A 100 mm diameter offers a good compromise between working area and operator control, enabling access to edges and curved surfaces. The cup design helps concentrate brushing action and maintain even wear across the bristle field.

Suitable for

• Removal of rust and loose paint from ferrous and non-ferrous parts
• Light deburring and edge cleaning after cutting or grinding
• Surface preparation before welding, soldering or painting
• Cleaning of corrugated or curved metal surfaces and corners
• Light polishing and finish work on softer metals such as brass, copper, and aluminum

Key specifications

• Mount type: M14 threaded arbor suitable for compatible angle grinders
• Brush diameter: 100 mm for moderate coverage and control
• Bristle material: brass wires designed to reduce scratching on sensitive surfaces
• Shape: cup brush for focused brushing and consistent contact
• Typical applications: rust removal, paint stripping, deburring, light polishing

How to use

Fit the brush onto the angle grinder spindle using the M14 threaded connection and ensure it is properly tightened according to the grinder manufacturer's instructions. Before full-speed operation, run the tool at a safe distance from the workpiece to confirm balance and correct mounting. Hold the grinder at a shallow angle and apply light, even pressure—allow the brush's bristles to perform the cutting action rather than forcing the tool. Move the brush steadily across the surface to avoid gouging and to achieve uniform results. Use appropriate feed speed and overlap passes for thorough cleaning.

Usage recommendations

Wear appropriate personal protective equipment, including eye protection, gloves and hearing protection. Use in well-ventilated areas and consider a dust mask when removing paint or heavy rust. Avoid excessive pressure and speeds beyond the brush's rated limit to prevent premature wear or bristle loss. Inspect the brush regularly for wire wear or damage and replace it if bristles are significantly worn or missing.
