Busch Fig. 415 Knife Edge Bur Kit of 11 - 1.0mm - 2.0mm

Cut narrow, clean seats and bright-cut lines in precious metal for stone setting work. The Busch Fig. 415 Knife Edge Bur Kit contains one each of 11 burs ranging from 1.0mm to 2.0mm, packaged together in a plastic storage container, giving stone setters a complete progression of sizes in a single purchase instead of sourcing each bur individually.

Busch Fig. 415 burs, also known as Lens burs, feature a 55-degree angle that produces narrow, precise cuts in precious metals. This geometry suits stone setting work where controlled material removal and clean seat edges are critical. The burs are manufactured from tungsten vanadium steel to ultra-high precision tolerances, for consistent performance and long tool life.
