Foredom Diamond Polishing Disc 10'' Dia. 40grit .5'' Ah

Description:

Diamond Polishing Disc 10'' dia. 40Grit .5'' AH is engineered for heavy-duty material reduction in dental laboratory procedures. With its coarse 40-grit diamond abrasive surface, this disc offers strong cutting performance ideal for initial shaping and contour adjustments of high-strength dental materials such as zirconia, feldspathic porcelain, lithium disilicate, and composite blocks. The disc�s large 10-inch diameter makes it exceptionally efficient for handling sizable frameworks, multiple units, or large prosthetic structures. This broader surface supports quick and even reduction, allowing dental technicians to achieve desired anatomical contours before switching to finer polishing stages. Its .5-inch arbor hole ensures compatibility with standard polishing motors, providing secure attachment and vibration-controlled rotation. This coarse disc is particularly valuable in removing bulk material during the early stages of crown, bridge, and implant-supported prosthetic fabrication. It allows precise shaping of margins, occlusal anatomy, and framework outlines without compromising structural integrity. The uniform distribution of diamond particles ensures consistent abrasion across the entire disc surface, which improves workflow predictability and reduces the risk of uneven reduction. While the 40-grit disc is intentionally aggressive, it is designed to minimize chipping when used properly, even on brittle ceramic materials. After using this disc, dental technicians typically transition to medium and fine grit discs for refinement and smoothing. Its strong cutting ability, durability, and efficiency make it indispensable in laboratory environments where precision shaping and reliable performance are essential.
