Foredom Cup Brush Steel Wire12 Mm Dia. 9.5mm L 2.35mm

Description:

The Cup brush steel wire 12mm dia. 9.5mm l 2.35mm is a robust dental laboratory brush designed for strong abrasive performance when working with metal frameworks and prosthetic hardware. Steel wire provides the highest level of cleaning and cutting action among wire-based brushes, making it ideal for technicians involved in fabrication of partial denture frameworks, orthodontic appliances, and implant-supported restorations (laboratory use). Its 12mm cup head supports broad engagement across metal surfaces, enabling efficient cleaning of major connectors, lingual plates, clasp assemblies, and attachment components. With a 9.5mm bristle height, the brush maintains structural stiffness needed for deep cleaning while allowing enough flexibility for precise directional control. The standard 2.35mm shank ensures compatibility with laboratory handpieces capable of handling high-torque polishing. This steel cup brush is especially useful in early finishing stages, such as removing investment residues after casting, eliminating oxide layers formed during soldering, cleaning weld joints, and decontaminating metal surfaces before polishing. Due to its aggressive nature, the brush is typically used prior to transitioning to brass wire or softer bristle brushes. The tool plays an essential role in prosthetic fabrication workflows where accurate metal preparation is critical for ensuring proper fit, attachment seating, and material bonding. Although strong, the fine wire gauge provides controlled abrasion rather than uncontrolled cutting, supporting both efficiency and precision. Overall, this steel wire cup brush is a dependable instrument for heavy-duty metal finishing tasks, offering reliability, durability, and high performance in dental laboratory applications.
