Wire cup brush Abraboro AB90416412 115 mm M14 — twisted wire 0.5 mm

Abraboro wire cup brush AB90416412 is a 115 mm diameter cup brush with an M14 mounting thread, equipped with twisted 0.5 mm steel wires. It is engineered for use with angle grinders and comparable rotary tools to deliver aggressive surface preparation. The brush removes rust, paint and scale, cleans welds, deburrs edges and blends metal surfaces to restore or prepare metalwork for further treatment.

Advantages

The twisted 0.5 mm steel wire pattern provides high abrasion and fast material removal while maintaining the shape of the cup for prolonged contact on flat and curved surfaces. The cup design ensures stable operation at rated speeds and allows access to edges and contours that flat brushes cannot reach. Constructed for professional and DIY use, the brush balances durability with effective cutting action on corrosion, coatings and weld spatter.

Suitable for

• Removing rust and old paint from metal surfaces
• Cleaning weld seams and removing slag or spatter
• Deburring and edge rounding on sheet metal and fabricated parts
• Preparing steel surfaces for painting, priming or coating
• Surface blending and smoothing after cutting or grinding

Key specifications

• Brush diameter: 115 mm
• Mounting thread: M14 compatible with standard angle grinders
• Wire type: twisted steel wire
• Wire diameter: 0.5 mm
• Brush shape: cup for edge and contour access
• Intended use: aggressive surface preparation on metal

How to use

Mount the cup brush securely on an angle grinder whose spindle matches the M14 thread. Inspect the brush for damage before use and ensure the tool's guard is fitted. Operate the grinder at the recommended speed range for the brush and apply light, even pressure; let the brush do the work rather than forcing it. Move the brush steadily across the workpiece to remove rust, paint or weld residue, and maintain consistent contact to achieve uniform surface preparation.

Usage recommendations

Use appropriate personal protective equipment including eye protection, gloves and hearing protection. Avoid excessive lateral force and do not use the brush on softer materials where aggressive wire may cause unwanted surface marring. Replace the brush if wires become excessively worn, distorted or if the cup is damaged. Follow the angle grinder manufacturer's safety instructions and recommended maximum RPM values for cup brushes.
