Swiss Round Finishing Bur Kit 9 Pieces 1.20mm to 4.00mm

This 9-piece kit brings together Otto Frei Swiss Tungsten Vanadium Round Finishing Burs in a curated size range spanning 1.20mm to 4.00mm — the most widely used bur type in the jewelry industry. Machine-made to ultra-high precision tolerances, Tungsten Vanadium steel burs are uniformly consistent from piece to piece, cutting precious metal smoothly and cleanly with no chatter or drag. The modern Swiss manufacturing equipment combined with expert Swiss steel hardening technique makes this line of burs a consistent best seller at Otto Frei.

Unlike High Speed Steel (HSS) burs, which are individually hand-cut and therefore subject to slight variation between pieces, Tungsten Vanadium burs are machine-produced to exacting standards, delivering repeatable performance across every size in the set. While HSS burs offer greater long-term durability, Tungsten Vanadium burs provide excellent value and consistent quality at a lower price point — making them an ideal choice for everyday setting work.

All burs in this kit feature 3/32" diameter shafts and arrive organized in a round plastic holder for easy bench storage and quick size selection.
