Key Features 

The Heavy Duty Braided Cup Brush delivers a range of advantages that set it apart from conventional alternatives: 

1. High-quality carbon steel braided wire: Provides greater durability and wear resistance. 
2. Aggressive cleaning action: Removes rust, paint, and embedded dirt in less time. 
3. Enhanced safety: Doe not shed wires during use. 
4. Shape retention: The braid retains its structure even under intensive work 
5. Universal compatibility: Suitable for use with ⅝”-11 spindle angle grinders (always consult the manufacturer’s manual). 

Recommended Applications 

This wire brush is primarily designed for cleaning carbon steel, but it can also be used on other ferrous metals when proper precautions are observed. Its most common applications include: 

• Rust removal: Ideal for restoring corroded metal components. 
• Paint removal: Effectively removes aged or deteriorated coatings without damaging the base material. 
• Light burr removal: Perfect for newly cut or machined parts. 
• Weld slag cleaning: Leaves joints clean and ready for further processing. 

Safe operating instructions 

Correct use of the FANDELI Braided Cup Brush not only guarantees a better finish, but also extends the life of the tool and protects the operator. 

1. Correct assembly: With the tool disconnected, screw the brush onto the angle grinder with a ⅝”-11 spindle.     
2. Initial test: Run the carding tool idle for 1 minute to check that it is not damaged.     
3. Working angle: Maintain an angle of less than 10° to the workpiece.                                
4. Controlled pressure: Do not apply excessive pressure; let the wire do the work.    
5. Personal protection: Wear leather gloves, safety glasses, a mask, hearing protection, and safety footwear.                 
6. Safe environment: Work in a well-ventilated area free of flammable materials. 

 Competitive advantages over other brushes 

The Heavy Duty Braided Cup Brush is no ordinary tool; it is designed to meet the demands of the industrial sector: 

• Greater wear resistance thanks to its optimized gauge braided wire.
• Lower risk of accidents due to filament breakage.
• More uniform finish in less time.
• Adaptability to multiple work environments, from machine shops to construction. 

Tips for extending the life of the brush 

• Do not exceed the maximum speed recommended by the grinder manufacturer.  
• Avoid prolonged contact on the same spot to prevent deformation of the braids.      
• Clean the brush after use to remove metal or paint residue.      
• Store it in a dry place protected from impact. 

Storage and Packaging 

To preserve product quality, the brush should be stored horizontally in a cool, dry place. Avoid drops or impacts that could deform the braided wires. 

• Internal packaging: 1 piece 
• External packaging: 60 pieces (for distribution; sale to the end user depends on the distributor or point of sale). 

The FANDELI Heavy Duty Braided Cup Brush (⅝”-11) is the perfect ally for those who need maximum efficiency and durability in metal cleaning and preparation work. Its robust construction, combined with a design optimized for intensive use, makes it a smart investment for workshops, factories, and maintenance companies. 

Whether removing rust, cleaning welds, or preparing surfaces for painting, this brush ensures a professional-quality finish with every use.
