Wire brush Abraboro AB90416421, 125 mm diameter, 22.2 mm bore

Abraboro AB90416421 is a 125 mm wire brush with a 22.2 mm central bore designed for mounting on angle grinders and compatible rotary tools. It is intended for mechanical surface preparation tasks such as removal of rust, paint, scale and burrs, as well as cleaning welds and preparing metal surfaces before coating. The brush construction provides consistent abrasive action across the working diameter while fitting standard 22.2 mm spindles used on many grinders.

Advantages

The Abraboro 125 mm wire brush delivers uniform material removal and surface cleaning thanks to its radial wire arrangement and balanced construction. The 22.2 mm bore ensures secure fitting on common angle grinders, reducing runout and vibration during use. Its diameter offers a trade-off between access and coverage: large enough to cover broader areas efficiently yet compact enough for controlled work in tighter spots. The brush is suitable for repeated workshop use and maintenance tasks where mechanical abrasion is required.

Suitable for

• Removing rust and scale from metal surfaces
• Removing old paint and coatings prior to repainting
• Cleaning weld seams and preparing joints for welding
• Deburring and edge blending on fabricated metal parts
• Surface preparation before application of primers and coatings

Key specifications

• Brush diameter: 125 mm
• Central bore diameter: 22.2 mm (for direct mounting on compatible spindles)
• Brush type: wire brush for mechanical abrasion and cleaning
• Application: rust, paint, scale removal, deburring, weld cleaning
• Compatible tool: angle grinders and rotary tools with 22.2 mm spindle

How to use

Mount the wire brush on the grinder spindle following the tool manufacturer's instructions and ensure the bore fits securely on the 22.2 mm spindle. Tighten the mounting nut to the specified torque and confirm that the brush is centered and free of wobble before switching on the tool. Operate the grinder at the recommended speed range for the brush and apply moderate, even pressure—allow the brush action to remove material rather than forcing it. Move the brush across the workpiece in steady passes, keeping the tool at an appropriate angle to the surface for effective cleaning while avoiding aggressive gouging.

Usage recommendations

Use appropriate personal protective equipment including eye protection, face shield, gloves and hearing protection. Inspect the brush for damage or loose wires before each use and do not use if the brush shows significant wear or distortion. Avoid exceeding the maximum RPM rating of your grinder and maintain steady motion to prevent localized overheating or gouging. For painted surfaces containing suspected lead or hazardous coatings, follow local regulations for containment and disposal.
