Foredom Diamond Bur Cone Xxxc 19mm L 12mm D 2.35mm

Description:

The Diamond bur Cone XXXC 19mm l 12mm d 2.35mm is engineered for maximum material removal during demanding restorative and prosthodontic procedures. With a larger 19 mm cone diameter and 12 mm abrasive length, this bur offers extended cutting reach and increased surface engagement for reshaping high-strength ceramics such as zirconia, lithium-disilicate, and feldspathic materials. The XXXC diamond grit provides ultra-aggressive abrasion, allowing rapid bulk reduction when time-consuming adjustments or significant contouring are required. Its cone geometry enables efficient removal along both flat and tapered surfaces. Clinicians benefit from the instrument�s ability to cut uniformly on axial walls, occlusal surfaces, and thick ceramic margins. In laboratory environments, it is commonly used during the initial sculpting of monolithic zirconia crowns, bridges, and long-span frameworks that require substantial contouring before fine detail and characterization are applied. The sheer cutting power of the XXXC grit makes it indispensable for situations where restorations arrive with excess volume or require major reshaping to achieve proper fit or occlusal clearance. When used intraorally, abundant water irrigation is essential to control thermal effects and maintain material stability. The standard 2.35 mm shank ensures compatibility with most contra-angle handpieces designed for high-load cutting. Following gross reduction with this bur, workflow progression typically involves stepping down to XXC, XC, and medium-grit burs to refine the surface and eliminate deep abrasive marks. Its size, grit, and versatility make it a cornerstone instrument for technicians and clinicians performing heavy ceramic modification.
