Komet 4ZR is a cylinder-round end, coarse grit diamond used for cutting all-ceramic crowns. The 4ZR can be used on all-ceramic crowns, including: Zirconium dioxide Lithium disilicate
Recommendations for Use: When cutting materials that tend to "jump" (ex. certain non-precious alloys), use the instrumentin the turbine and apply a low contact pressure To take full advantage of the instrument& shape and size, apply the instrument at an angle of45 degrees to the crown Always apply sufficient coolant (at least 50 ml/min) Do not exceed a maximum contact pressure of 2N
