Wire cup brush Szczotpol 125 mm with wavy wire, M14 thread

The Szczotpol wire cup brush, 125 mm in diameter with wavy (crimped) steel wire filaments and an M14 threaded arbor, is intended for surface preparation on metal. It removes rust, flaking paint, scale and welding residues, and can also deburr edges and clean seams. The brush is compatible with angle grinders that accept M14 mounting and is suitable for both industrial environments and DIY metalwork.

Advantages

The wavy steel filaments provide an aggressive yet flexible action that balances material removal with surface finish control, reducing the risk of gouging. The cup brush form concentrates brushing force for efficient cleaning of flat areas and contours. The M14 threaded arbor ensures quick, secure fitting to commonly used angle grinders for uninterrupted work.

Suitable for

• Removal of rust and loose paint from steel and iron surfaces
• Eliminating scale and oxidation prior to painting or welding
• Cleaning weld seams and removing weld slag
• Deburring and preparing metal edges and profiles
• Surface conditioning before priming or coating

Key specifications

• Brush diameter: 125 mm
• Wire type: wavy (crimped) steel filaments
• Brush shape: cup
• Mounting thread: M14 threaded arbor for angle grinders
• Typical application speed: suitable for standard angle grinder RPM ranges (observe tool limits)

How to use

Mount the cup brush securely onto an angle grinder with M14 fitting following the grinder manufacturer’s instructions. Before starting work, check that the brush is free from damage and that the grinder’s guard is in place. Operate the grinder at a steady speed, applying light to moderate pressure and keeping the brush flat or at a slight angle to the surface to avoid concentrated gouging. Move the brush evenly across the workpiece until the desired level of cleaning or surface preparation is achieved. Allow rotating brush to stop completely before setting the tool down.

Usage recommendations

Use appropriate personal protective equipment: eye protection, gloves, hearing protection and a dust mask. Do not exceed the maximum safe speed of the angle grinder or the brush; follow both tool and accessory safety guidelines. For thin or soft metals, test on a small area to ensure the wire filaments do not over-abrade the surface.
