Wire cup brush Smart 125 mm braided disc, bent type, with grease fitting

Wire cup brush Smart 125 mm braided disc, bent type, with grease fitting is a 125 mm diameter braided-wire cup brush designed for heavy-duty surface cleaning and metal preparation. The bent (offset) profile improves contact angle and access to edges and irregular surfaces while the grease fitting allows lubrication of the arbor area for smoother rotation and reduced wear. This accessory is intended for use with angle grinders and bench tools that accept 125 mm cup brushes and is suitable for tasks such as rust and paint removal, deburring and preparing metal before welding or coating.

Advantages

The braided-wire construction provides dense, durable filaments that resist breakage and maintain aggressive brushing action over extended use. The bent or offset cup design enhances operator control and improves contact with uneven surfaces and profiles. An integrated grease fitting simplifies maintenance by enabling periodic lubrication of the central hub, which helps reduce heat and extend bearing or arbor life. The 125 mm size balances coverage and maneuverability for workshop and on-site tasks.

Suitable for

• Removing rust and old coatings from metal surfaces
• Deburring welded joints and cut edges
• Surface preparation before painting, galvanizing or welding
• Cleaning castings, profiles and structural elements

Key specifications

• Brush type: braided wire cup, bent/offset profile
• Diameter: 125 mm
• Attachment: central arbor mount compatible with 125 mm cup brush spindles
• Wire material: steel braided filaments for aggressive cleaning
• Maintenance: integrated grease fitting for hub lubrication
• Intended use: angle grinders and bench tools rated for 125 mm cup brushes

How to use

Mount the cup brush on a tool that accepts 125 mm cup accessories, ensuring the arbor and locking nut are compatible and tightened to the tool manufacturer’s recommended torque. Wear appropriate personal protective equipment including eye and face protection, gloves and hearing protection. Start the tool at low speed to check balance and clearance, then operate at the tool’s recommended speed for wire cup brushes. Use steady light-to-moderate pressure; avoid excessive force that could overload the tool or deform the wire filaments. Periodically stop to inspect the brush for wear, damage or loose wires.

Usage recommendations

Use on clean, dry surfaces and select the appropriate grinder speed and feed pressure for the material being worked. Regularly apply lubricant via the grease fitting to maintain hub performance. Replace the brush when filament wear or damage reduces effectiveness or creates a safety risk. Follow the angle grinder and workplace safety guidelines for abrasive wire accessories.
