Fresas de carburo Busch Fig. 413AU para engaste, vástago de 3/32", de 0,80 mm a 3,00 mm, por unidad

These burs cut a precise seat so faceted stones sit firmly in flush and bezel settings. Finally, the stone setting bur setters have been waiting for. Busch Fig. 413AU ultra-precise stone setting burs are made from hot-isostatically compressed, finest-grain carbide for maximum durability and cutting power, on a 3/32" shank. They are super sharp and super flexible, outlasting tungsten vanadium and HSS burs, especially in hard jewelry alloys like platinum, titanium, and white gold. Each bur cuts cleanly across a wide RPM range.

Sold by the piece. A complete 23-piece set is available separately (see related products).

• Secure the workpiece and keep the bur square to avoid tapered or oval seats.
