Wire cup brush Szczotpol model N157, 100 mm diameter, 6 mm shank, A40 abrasive

Szczotpol wire cup brush model N157 with a 100 mm diameter and a 6 mm shank is designed for aggressive surface preparation and cleaning. The brush uses A40 abrasive-grade wire filaments to remove rust, paint and oxidation, deburr edges and prepare metal surfaces for further treatment. It attaches to drills and rotary tools that accept a 6 mm shank and is balanced for stable rotation during medium- to heavy-duty tasks.

Advantages

The wire cup brush delivers consistent material removal thanks to uniform A40 wire filaments and a wide 100 mm contact area that reduces the number of passes required. The 6 mm shank ensures compatibility with most handheld drills and rotary tools while providing secure mounting and minimal wobble. Its construction maintains filament retention under high-speed rotation, offering reliable performance for cleaning, rust removal and paint stripping on steel and other metals.

Suitable for

• Removing rust, scale and old paint from metal surfaces
• Deburring and edge blending after cutting or welding
• Preparing metal surfaces before welding, priming or painting
• Cleaning automotive components, chassis parts and tools
• General maintenance and surface conditioning in workshops

Key specifications

• Brush type: wire cup brush with A40 abrasive-grade filaments
• Diameter: 100 mm
• Shank diameter: 6 mm
• Filament material: abrasive wire suitable for metalworking
• Intended operating range: medium- to high-speed rotary tools

How to use

Secure the brush in the drill chuck or rotary tool collet so the 6 mm shank is fully seated and tightened. Start at low speed to check balance and clearance, then increase speed to the tool’s recommended operating range for wire cup brushes. Apply steady, even pressure and move the brush across the workpiece; avoid excessive force that may accelerate wear or damage the surface. Use appropriate directional movement to reach weld seams, corners and irregular surfaces.

Usage recommendations

Wear eye and hand protection and a dust mask when using the brush. Test on a small area to confirm the aggressiveness of A40 filaments for the specific material. Replace the brush if wires become excessively worn or dislodged. Keep workpiece and brush cool by intermittent operation to prolong filament life.
