Vanadium Steel

Sets of 9 or 12 Helvetica vanadium steel hart (bearing cutter) burs provided in plastic stands with clear covers. Made in Switzerland. 3/32" shanks.

The Basics

  • Hart (Bearing Cutter) Burs are used to cut seats in prongs, flush settings, & channels. They are available with 45°, 70° or 90° cutting angles. They can also be used for bright cutting.
  • Vanadium Steel burs are economically priced. They cut precisely when new, but don't retain their sharpness as long as other steel alloys. They're used at low speeds.
  • 3/32" dia. shanks are the jeweler's preferred standard for burs and small rotary tools. They fit the adjustable chucks found on most flexshaft handpieces as well as 3/32" handpiece collets.
