What this operative carbide bur is for

The R36 Economy Invert Cone tungsten carbide bur is designed for routine cavity preparation, crown and bridge adjustment, and restorative material reduction when lower replacement cost is the main priority.

  • Supports standard chairside cutting and adjustment tasks with practical handling.
  • Useful for routine preparation, training, and high-volume daily replacement.
  • Service life and cutting stability are lower than the High Quality version.
  • Good choice when economical use is more important than longest bur life.
