Swiss Cone Square Cross Cut Bur Kit 11 Pieces. 0.60mm To 2.20mm

This 11-piece kit brings together Swiss-made Tungsten Vanadium Cone Square Cross Cut Burs in a graduated size range from 0.60mm to 2.30mm. Tungsten Vanadium burs are the most popular burs used in the jewelry industry, and for good reason: manufactured on modern precision equipment using Swiss steel hardening expertise, these burs are machine-made to ultra-high precision tolerances. The result is a bur that is uniformly consistent from piece to piece, cutting precious metal smoothly and cleanly with no chatter or drag.

Unlike High Speed Steel (HSS) burs, which are individually hand-cut and therefore variable, Tungsten Vanadium burs are mechanically produced so every bur in this set performs the same way. While HSS burs offer greater longevity, Tungsten Vanadium burs deliver excellent value and reliable performance, making them the best-selling bur type at Otto Frei. The Cone Square Cross Cut profile is ideal for setting stones, refining seats, and working in tight areas where a precise conical point is required. The cross-cut pattern breaks up chips and reduces heat buildup during use.

All burs in this set feature standard 3/32" diameter shafts, compatible with most flex-shaft handpieces and rotary tools. The set ships in a round plastic holder that keeps each bur organized and protected.
