Foredom Radial Bristle Disc Blue 400 Gr 20mm D 1.6mm Ah

Description:

The Radial bristle disc blue 400 gr 20mm d 1.6mm AH is built for situations where efficient contouring, material reduction, and foundational surface shaping are required in dental restorative and laboratory applications. Featuring 400-grit coarse bristles, this disc provides more aggressive abrasion than finer grits, making it a suitable choice for initial shaping after bulk material placement or during appliance adjustments. Its 20 mm diameter provides an optimal balance between accessibility and surface coverage, allowing clinicians and technicians to shape line angles, flatten high spots, contour proximal surfaces, and refine the overall morphology of composite or acrylic restorations. The flexible polymer bristles contain embedded abrasives that cut smoothly while reducing the risk of chatter or uncontrolled removal commonly associated with rigid burs or stones. This disc is compatible with a 1.6 mm mandrel system, suited for slow-speed handpieces used in chairside or benchtop procedures. It is often used for trimming orthodontic resin attachments, adjusting soft-tissue fitting surfaces on mouth guards, reducing high spots on provisional crowns, and shaping acrylic denture bases prior to fine finishing steps. The blue bristle system disperses heat well, preventing thermal damage to polymeric restorative materials. Its structure also allows debris to be expelled during rotation, preventing clogging and maintaining consistent abrasive performance. When followed by medium- and fine-grit radial bristle discs, it forms part of an efficient multi-step abrasive workflow that results in smooth, contoured dental restorations ready for polishing.
