This 36-piece master kit brings together a comprehensive range of Swiss-made Tungsten Vanadium ball burs, housed in a wooden storage box. Tungsten Vanadium ball burs are the most widely used burs in the jewelry industry, prized for their machine-made precision and consistent performance. Manufactured to ultra-high tolerance standards, these burs cut precious metal smoothly and cleanly—with no chatter or drag.

Unlike High Speed Steel (HSS) burs, which are individually hand-cut and vary slightly from piece to piece, Tungsten Vanadium burs are machine-made to be uniformly consistent. This makes them an excellent choice for repetitive setting work where predictability matters. Note that while Tungsten Vanadium burs offer outstanding value and precision, they are generally not as long-lasting as USA-made High Speed Steel burs.

All burs in this set feature 3/32" diameter shafts, compatible with standard flex shaft handpieces and rotary tools used in jewelry making and stone setting.
