Swiss Cylinder Square Cross Cut Bur Kit. 12 Pieces. 0.70mm To 2.70mm

This 12-piece kit brings together Swiss-made Tungsten Vanadium Cylinder Square Cross Cut Burs spanning 0.70mm to 2.70mm — a comprehensive range for precise metal removal across everyday jewelry work. Tungsten Vanadium burs are the most widely used burs in the jewelry industry, prized for their machine-made uniformity and ultra-high precision tolerances. Each bur cuts precious metal smoothly and cleanly, with no chatter or drag.

Unlike High Speed Steel (HSS) burs, which are individually hand-cut and can vary from piece to piece, Tungsten Vanadium burs are manufactured to consistent, repeatable standards. While HSS burs offer greater long-term durability, Tungsten Vanadium burs deliver reliable performance at a lower price point—making this kit an excellent value for bench jewelers who work at volume. All burs feature a standard 3/32" diameter shank compatible with common flex shaft handpieces and rotary tools.

The set is stored in a round plastic holder (part #119.248) that keeps each bur organized and protected at the bench.

Notes

Tungsten Vanadium burs are not as long-lasting as USA-made High Speed Steel burs. The source data lists one size as "0.09mm" — this is most likely a typographical error for 0.90mm, consistent with the progressive size sequence of the kit. Verify with Otto Frei if exact size confirmation is required.
