About

The 4ZR is used for cutting all-ceramic crowns, and works especially well on extremely hard ceramic materials such as zirconium dioxide.

Recommendations for Use:

When cutting materials that tend to "jump" (ex. certain non-precious alloys), use the instrument in the turbine and apply a low contact pressure
To take full advantage of the instrument's shape and size, apply the instrument at an angle of 45 degrees to the crown
Always apply sufficient coolant (at least 50 ml/min)
Do not exceed a maximum contact pressure of 2N

Benefits:

Tip transversing blade on tungsten carbide burs to facilitate penetration of the crown material
Time savings
Reduced heat generation thanks to effective chip spaces
Outstanding durability
