Foredom Diamond Polishing Disc 6'' Dia. 40grit .5'' Ah

Description:

Diamond Polishing Disc 6'' dia. 40Grit .5'' AH is a heavy-duty dental laboratory disc intended for rapid material reduction and shaping during the early stages of prosthetic fabrication. With its coarse 40-grit diamond abrasive surface, the disc is capable of removing substantial material from zirconia, metal alloys, ceramics, and acrylics with speed and consistency. This makes it especially valuable during the initial contouring of dental crowns, bridges, implant components, and denture bases. The larger 6-inch diameter provides a broad working area, allowing dental technicians to work efficiently on bigger or multiple units at once. Its size also enhances disc stability, minimizing vibration during use and ensuring even pressure distribution across the surface. The .5-inch arbor hole allows reliable attachment to polishing motors and bench units commonly used in dental laboratories. This disc is typically used during the rough shaping stage when restorations need significant adjustment to achieve approximate anatomical form. Its aggressive abrasive power helps shorten workflow time and prepare the restoration for subsequent refinement using medium- and fine-grit discs. Despite its coarse nature, the diamond bonding ensures durability and controlled abrasion, reducing the risk of chipping brittle materials like ceramic or zirconia when handled properly. For dental professionals who require efficiency and speed in prosthetic fabrication, this disc offers a dependable solution for early-stage grinding tasks. The 6-inch 40-grit diamond polishing disc is a foundational tool in many laboratories, forming the first step in producing precise, functional, and esthetically refined dental restorations.
