Product Details

Description:

The Cup brush brass wire 12mm dia. 9.5mm l 2.35mm is an essential metal-finishing tool used in dental laboratories for surface preparation and intermediate cleaning of metal components. Brass wire offers a softer abrasive profile than steel, making it ideal for technicians who require effective cleaning without leaving deep scratches on chrome-cobalt frameworks, removable partial denture components, and orthodontic wires. The 12mm cup shape enables wide-area metal cleaning, allowing uniform abrasion across structural frameworks, connectors, clasps, and solder joints. The 9.5mm bristle length provides enough body for effective contact with the metal surface while maintaining flexibility during contouring and preparation tasks. The 2.35mm shank is compatible with micromotors and standard lab handpieces. This brush is particularly effective in removing oxide layers, polishing compound residues, and investment particles left after casting. It can also be used to refine the texture of metal surfaces before acrylic processing, veneering, or ceramic layering. Because brass is less aggressive than steel, it allows technicians to work confidently on delicate or thin metal areas without risking structural compromise. Its balanced abrasive action supports tasks such as smoothing clasp undersides, refining occlusal rest seats, and cleaning intricate prosthetic components. The brush also helps enhance surface retention when preparing metal frameworks for bonding with acrylic or composite materials. Overall, this brass wire cup brush is a practical and reliable laboratory tool, offering controlled abrasive performance ideal for metal preparation and restorative fabrication.
