Komet's ZR943 diamond disk is designed to cut zirconia.
Komet USA this week announced a diamond disk that cuts zirconia at high speeds.

Komet's ZR943 diamond disk is designed to cut off sprues from pressed ceramics and to separate the coping from the HIP zirconia blank. Available in FG shank only, the ZR943 disk is obtainable in three sizes (065, 080, and 100). With a medium grit of 100 µm, it has a 1-mm coating of quality industrial diamonds on 0.3 mm of the disk's width.

Used at optimal speed of 160,000 rpm and with sufficient water cooling, the ZR943 diamond disk is also suited for the separation and contouring of veneer ceramics. However, these disks are not designed for intraoral use.
