Busch U-taper burs made of carbide for Princess Cut, Fig. 2K-AU / HM

The corners of the gemstones themselves, as well as the corners of the settings, are critical areas, especially when setting angular gemstones such as Princess Cut diamonds. In order to avoid damaging the corners of the gemstones when fitting them into square bezel settings, for example, it makes sense to optimise the corners of the setting to the geometry of the gemstones. The figure 2K-AU, with its smooth face, offers an optimum solution for this work step. The smooth, non-toothed face avoids unwanted milling contacts in the axial direction. Existing polished edges in the axial direction are therefore not damaged by the use of the 2K-AU.
