4ZRS.314.016 pack unit 5

Komet's 4ZRS Jackie is a coarse-grit diamond used for cutting, slitting and removing all-ceramic crowns. The 4ZR can be used on all-ceramic crowns, including:

• Zirconia / Zirconium dioxide
• Lithium disilicate

Benefits:

• Creates lingual, occlusal and buccal separating joints due to its tapered 4 mm working length
• Withstands friction created by all-ceramic crowns due to having more diamond particles closer together on the blank

Recommendations for Use:

• Use a generous amount of water and light hand 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
