Wire cup brush GEKO G00590-1 brass-plated 65 mm M14 for angle grinders

GEKO wire cup brush G00590-1 is a 65 mm brass-plated wire cup designed for attachment to angle grinders with an M14 threaded arbor. The brush features densely packed brass-plated steel filaments arranged in a cup shape to access curved and flat surfaces. It is intended for surface cleaning tasks including removal of rust, paint and scale, light deburring, and preparing metal surfaces before welding or painting. The compact cup diameter provides control and access in confined areas while delivering consistent cleaning performance on ferrous and non-ferrous metals.

Advantages

The brass-plated steel filaments combine good abrasion resistance with reduced sparking compared with plain steel, improving operator visibility and making the brush suitable for a range of metalworking environments. The cup form holds filaments securely to maintain shape during rotation, ensuring even contact with the workpiece. The 65 mm diameter balances reach and precision, allowing work in tighter spots without sacrificing material removal efficiency. Threaded M14 connection ensures compatibility with common angle grinders equipped with the matching arbor.

Suitable for

• Removing rust and old paint from metal surfaces
• Surface preparation before welding or painting
• Light to medium deburring of edges and seams
• Cleaning weld spatter and scale
• Restoration and maintenance of metal structures and tools

Key specifications

• Cup diameter: 65 mm
• Filament material: brass-plated steel
• Mounting thread: M14 (for angle grinders)
• Shape: cup brush
• Intended use: surface cleaning, rust/paint removal, deburring, surface preparation

How to use

Fit the wire cup brush onto an angle grinder with the appropriate M14 threaded arbor, ensuring the tool is disconnected from power during installation. Secure the brush according to the grinder manufacturer’s instructions and perform a short spin test at low speed to confirm proper mounting and absence of wobble. When operating, hold the grinder with a firm two-handed grip and apply light, steady pressure to the workpiece, moving the brush across the surface to avoid concentrating on one spot. Use appropriate grinder speed and avoid excessive force to prevent premature filament wear and workpiece damage.

Usage recommendations

Always wear eye protection, gloves, and suitable respiratory protection when working with wire brushes. Select the brush for light to medium-duty cleaning tasks and replace it when filaments are significantly worn or bent. Avoid use on delicate finishes; test on a small area first. Follow the angle grinder manufacturer’s safety guidelines, maintain proper rotational speed limits, and keep bystanders clear of the work area.
