Swiss Ball Bur Kit-17 Piece-0.5mm to 3.0mm

This 17-piece kit brings together Swiss-made Tungsten Vanadium ball burs in a carefully selected size progression — from 0.50mm up to 3.30mm — giving jewelers a comprehensive range of precision cutting tools in a single, organized set. Tungsten Vanadium steel burs are the most popular burs used in the jewelry industry, prized for their machine-made uniformity and ability to cut precious metals smoothly and cleanly with no chatter or drag.

Unlike High Speed Steel (HSS) burs, which are individually hand-cut and vary slightly from piece to piece, Tungsten Vanadium burs are produced on modern equipment to ultra-high precision tolerances, making every bur in this set uniformly perfect. These burs are manufactured in Switzerland, where advanced machinery and Swiss steel hardening expertise combine to produce a consistently high-performing tool — making this line Otto Frei's best-selling bur brand. Note that while Tungsten Vanadium burs deliver excellent precision and value, they are generally not as durable as USA-made HSS burs.

All burs in this set feature 3/32" diameter shafts and are stored in a round plastic bur holder included with the kit.
