Swiss Fig. 5 cone burs in larger diameters are designed for shaping and enlarging tapered openings in precious metals. The straight cone profile provides controlled stock removal and clean definition, making them well suited for heavier bench work where accuracy is still important.

Features

  • Fig. 5 straight cone profile for tapered cuts and shaping
  • Manufactured from tungsten vanadium steel for strength and edge retention
  • Precision-made to tight tolerances for consistent performance
  • Larger diameters ideal for bold settings and heavier material removal
  • Preferred by many jewelers for everyday reliability
  • Sold individually
