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

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. This assortment gives stone setters a complete progression of sizes in a single purchase, eliminating the need to source 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 is especially well-suited to 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, ensuring consistent performance and long tool life.
