Foredom Cup Brush Black Bristle12 Mm Dia. 9.5mm L 2.35mm

Description:

Cup brush black bristle 12mm dia. 9.5mm l 2.35mm is a durable and moderately firm polishing brush suitable for dental professionals requiring greater abrasive strength during restorative and laboratory finishing procedures. Black bristle fibers provide enhanced stiffness, making the brush ideal for shaping and smoothing acrylic appliances, trimming provisional restorations, and performing intermediate finishing on composite materials. Designed with a 12mm cup configuration, the brush offers efficient coverage across large or rounded surfaces, improving working speed and consistency. The 9.5mm bristle length provides an excellent balance between flexibility and structural firmness, allowing the brush to adapt to curved anatomical forms while delivering effective polishing force. The 2.35mm shank ensures compatibility with standard slow-speed polishing handpieces. This brush is frequently used after initial contouring with carbide burs or abrasive stones. It helps remove scratch marks, even out textures, and prepare surfaces for finer polishing systems. Due to its firmer nature, it performs well in shaping areas of denture acrylic, orthodontic retainers, or splint materials prior to soft polishing steps. In the laboratory, it assists in refining clasp areas, finishing appliance borders, smoothing cast surfaces, and cleaning minor irregularities. When combined with pumice or abrasive polishing compounds, it provides consistent, controlled material removal. Its durability and moderate abrasiveness make it a reliable mid-stage polishing tool, bridging the gap between heavy contouring and delicate final finishing processes.
