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

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



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
