Swiss 90 Degree Hart Bur Master Kit 28 Pieces 0.90 mm To 5.00 mm

This 29-piece master kit brings together a comprehensive range of Swiss-made Tungsten Vanadium 90° Hart Burs in a single convenient set. Hart burs are used by jewelers and stone setters to cut precise seats in prongs and channels, making them an essential tool for professional stone setting work. The set spans sizes from 0.90 mm to 5.00 mm and includes a wood storage box, keeping every bur organized and protected at the bench.

Tungsten Vanadium vs. High Speed Steel (HSS) Burs: Tungsten Vanadium steel burs are the most popular burs in the jewelry industry. Machine-made to ultra-high precision tolerances, they 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 are exactly alike. Tungsten Vanadium burs are not as durable as USA-made High Speed Steel burs, but they typically cost less.
