Ronix 100mm Crimped Wire Cup Brush – Premium Quality for Effective Surface Preparation

The Ronix 100mm Crimped Wire Cup Brush (Model RH-9941) is a premium-quality accessory designed for professional surface preparation and cleaning tasks. The crimped wire design provides a softer, more flexible brushing action compared to twisted knot brushes, making it ideal for lighter-duty applications such as smoothing, cleaning welds, blending edges, and removing light surface rust or old paint without overly aggressive material removal. The 100mm (4-inch) diameter is perfectly sized for use with standard angle grinders. Constructed to the “RONIX Standard,” this cup brush features high-quality wire for maximum durability and long life. It is an essential tool for metalworkers, restorers, and general contractors requiring a clean, prepped surface before painting or welding.

Application Instructions

• Safety First: ALWAYS wear heavy-duty safety goggles, a face shield, and protective clothing.
• Mounting: Securely thread the cup brush onto the angle grinder spindle. Ensure the grinder’s RPM does not exceed the brush’s maximum safe speed (typically listed on the side of the brush).
• Operation: Start the grinder and bring the brush into contact with the surface at a slight angle.
• Technique: Use consistent, sweeping motions, letting the tips of the wires do the work. Do not press too hard.

Pro Tips

• Wear a leather apron or thick clothing to protect against flying wires and debris.
• Never use a wire brush near others without proper shielding, and ensure the work area is clear.
• Store the brush carefully to prevent damage to the crimped wires, which can cause premature failure.
• Use a knotted wire cup brush for extremely heavy rust or scale removal; use the crimped for finishing.
• Replace the brush when the wires become excessively short or significantly damaged.
