The Swiss Cup Bur Assortment brings together 9 essential sizes of Swiss-made Tungsten Vanadium Cup Burs in a single convenient plastic container — giving jewelers an immediate, ready-to-use range from 0.90mm to 2.30mm. Cup burs are among the most widely used burs in the jewelry industry, prized for setting stones, rounding prong tips, and refining seat edges with speed and control.

Tungsten Vanadium steel burs are machine-made to ultra-high precision tolerances, producing cuts that are uniformly smooth and clean with no chatter or drag on precious metal. Unlike High Speed Steel (HSS) burs, which are individually hand-cut and therefore vary from piece to piece, Tungsten Vanadium burs are mechanically consistent — every bur in this set performs predictably. The most modern manufacturing equipment combined with Swiss steel hardening expertise makes this line of burs a top seller for professional bench jewelers. All burs in this assortment feature the standard 3/32" diameter shank, compatible with most flex shafts and rotary handpieces.

Note that while Tungsten Vanadium burs offer exceptional precision and value, they are not as long-lasting as USA-made High Speed Steel burs and are typically available at a lower price point.
