Kit de fraises Hart peu profondes à 70° suisses, 15 pièces, de 1,00 mm à 3,50 mm

Build precise prong and channel seats with confidence using this 15-piece Swiss 70° Shallow Hart Bur Kit. Spanning 1.00mm to 3.50mm, this comprehensive set covers the most commonly needed sizes for stone-setting work and arrives ready to use in a round plastic storage holder.

Each bur in this kit is made from Swiss Tungsten Vanadium Steel, machine-manufactured to ultra-high precision tolerances. The result is a bur that cuts precious metal smoothly and cleanly — with no chatter or drag — and is uniformly consistent from piece to piece. Combined with Swiss steel hardening expertise, this line of burs is among the most trusted in the jewelry industry.

Tungsten Vanadium vs. High Speed Steel (HSS)

Tungsten Vanadium Steel burs are the most widely used burs in the jewelry industry. Machine-made to precise tolerances, they are uniformly consistent and deliver smooth, clean cuts in precious metal. High Speed Steel (HSS) burs are individually hand-cut, meaning no two are exactly alike. HSS burs — particularly USA-made versions — tend to be longer-lasting than Tungsten Vanadium burs. Tungsten Vanadium burs typically cost less than HSS burs.
