The Kerr Zir-CUT Diamond Bur (Z878K-021) is a high-performance rotary instrument engineered for efficient reduction and contouring of zirconia, ceramic, and other high-strength restorative materials. Its exclusive Z-Grit diamond coating and bonding technology reduce micro-fractures while providing aggressive yet controlled cutting, and the concentric design minimizes vibration for smooth, precise adjustment and finishing. The friction grip shank ensures secure seating in high-speed handpieces, making it ideal for crown adjustment, bridge refinement, and ceramic modification procedures.
