Function
The bur holder is a Zirkonzahn CAD/CAM system accessory. It is used to keep the various types of burs in order. The bur holder is available in three different versions (for zirconia, PMMA and wax).

Application
Thanks to its handy and space-saving shape, the bur holder can be applied to the milling unit in any position. The bur holder is magnetic and thus always has to be applied to a metal surface. Each bur holder contains six milling burs.
 
The markings on the bur holder – referring to the material for which it is indicated (zirconia, PMMA, wax) and its dimensions (2 L, 1 L, 0.5 S, 1.5 A, 0.6 A, 0.3 C) – allow for greater processing speed. They also make it easy to always keep your working tools in order and ready for use.

Note
Never place the bur holder too close to mobile components (tracks) to avoid any resulting shocks and damages. Position the bur holder so that the suspended tubes do not tangle with the burs.
