Swiss Advance Stone Setting Bur Kit of 30 Pieces

This 30-piece kit brings together the most essential Swiss-made Tungsten Vanadium stone setting burs and twist drills used in professional jewelry work. Tungsten Vanadium burs are machine-made to ultra-high precision tolerances, producing uniformly consistent geometry that cuts precious metal smoothly and cleanly — with no chatter or drag. This precision manufacturing sets them apart from High Speed Steel (HSS) burs, which are individually hand-cut and therefore variable from piece to piece.

The kit is assembled from Otto Frei's own line of Swiss Tungsten Vanadium burs, produced using the most modern equipment available combined with Swiss steel hardening expertise — making this line a bestseller among professional jewelers. All burs in this set feature 3/32" diameter shafts. The 30-piece set arrives organized in a round plastic holder for bench-ready storage.

Note: Tungsten Vanadium burs are not as long-lasting as USA-made High Speed Steel burs, but typically cost less and offer superior uniformity.
