The radial bristle discs are designed for professional deburring, polishing, and surface treatment of metals – ideal for goldsmiths, jewelry designers, and workshops working with precious metals and intricate details.

The bristles are made of flexible synthetic fibers embedded with an abrasive material harder than most metals. This ensures effective removal of oxides and impurities – without the need for messy polishing compounds. At the same time, these discs generate far less heat than traditional rubber wheels, making them suitable even for delicate surfaces.

The radial design ensures consistent contact with the surface, making the bristle discs perfect for contours, rounded edges, and hard-to-reach areas on jewelry and pieces in platinum, gold, silver, copper, tin, and brass. They can be used individually for precision work or stacked for greater coverage.

Radial bristle discs are available in four grit sizes, giving full control over abrasion and desired finish:

• K80 – yellow: Coarse deburring and rapid material removal
• K220 – red: Medium finish and light surface treatment
• K400 – blue: Fine polishing and smooth finish on metal surfaces
• X-fin – pink: Very fine polishing and gentle deburring of delicate surfaces

Specifications:

• Diameter: Ø19 mm
• Type: C – curved, flexible design
• Recommended speed: max. 6,000 rpm (recommended below max for longer life)
• Mounts on mandrel. Sold separately (article no. ED00305 or ED00308).

Advantages:

• Consistent and precise deburring – even on complex pieces
• Long service life with constant abrasive effect
• Flexible design that follows contours and edges
• Quick and effective removal of rust, weld burns, paint, and coatings
• Less heat generation than rubber wheels – gentle on sensitive surfaces
• Can be used individually or stacked for larger coverage
