Swiss 90 Degree Hart Bur Kit 17 Pieces 0.90mm To 4.00mm

This 17 piece bur set is made up of Swiss Made Tungsten Vanadium 90° Hart Burs. These burs are used for making cuts in prongs and channels for setting stones. Tungsten Vanadium Steel Burs are the most popular burs used in the jewelry industry. Machine made to ultra high precision tolerances, Tungsten Vanadium steel burs are uniformly perfect, and cut precious metal smoothly and cleanly, with no chatter or drag. High Speed Steel (HSS) burs are individually hand cut so no two burs are exactly alike. Tungsten vanadium burs are not as long-lasting as USA made High Speed Steel burs. Tungsten Vanadium burs usually cost less than HSS burs.

This 90° Hart Bur Set is made up of Otto Frei Swiss Tungsten Vanadium burs. The most modern equipment in the world combined with Swiss steel hardening know-how makes this brand of burs our best seller. The burs have 3/32" diameter shafts.
