Busch Inverted Cone Burs

Busch Inverted Cone Burs

Vanadium Steel

Vanadium steel inverted cone burs made in Germany by Busch®. 3/32" shanks.

The Basics

  • Inverted Cone Burs are shaped like an upside-down cone and are well-suited for making undercuts for stone setting and remove excess solder from tight spaces.
  • 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.
