Wire cup brush Abraboro AB99040009 — 65 mm, M14 shank, twisted wire 0.35 mm

The Abraboro wire cup brush AB99040009 is a 65 mm diameter cleaning accessory with an M14 threaded shank and twisted steel wire filaments of 0.35 mm thickness. Designed to be mounted on angle grinders or compatible rotary tools with an M14 spindle, this cup brush is intended for aggressive surface work on metal, providing effective removal of rust, paint, scale and burrs while preparing surfaces for further treatment.

Advantages

The twisted wire construction delivers a higher mechanical cutting action compared with knotted or crimped filaments, improving material removal rate on stubborn corrosion and coatings. The compact 65 mm cup size offers controlled contact area for more precise cleaning in confined or irregular spaces. The M14 shank ensures compatibility with a wide range of common angle grinders and rotary tools. Filament thickness of 0.35 mm balances durability and cutting aggressiveness for repeatable performance in workshop and industrial environments.

Suitable for

• Removing rust and old paint from steel and iron surfaces
• Stripping scale, weld spatter and oxidation
• Deburring edges and blending seams on metal parts
• Surface preparation before welding, priming or painting

Key specifications

• Brush diameter: 65 mm
• Shank/thread type: M14 threaded shank for angle grinders
• Filament type: twisted steel wire
• Filament thickness: 0.35 mm
• Brush shape: cup brush for surface contact and edge access

How to use

Securely mount the Abraboro cup brush onto the tool spindle with the M14 connection, following the tool manufacturer's instructions for correct tightening and guard placement. Operate the grinder at the recommended speed range for wire cup brushes and apply moderate, even pressure; avoid excessive force which can reduce filament life and increase vibration. Move the brush steadily across the work surface, keeping the contact angle consistent to achieve uniform material removal. Replace the brush when filaments are excessively worn or damaged.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and hearing protection. Ensure tool guards are fitted and that the workpiece is securely clamped. Test on a small area to confirm compatibility with the substrate and finishing requirements before full application.
