The Basics

  • Vanadium Steel burs and drills are economically priced. They cut precisely when new, but lose their sharpness faster than hss and carbide steel. They are used at lower 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.
