SINCEN Dental diamond-coated glass ceramic milling burs for Sirona CEREC MC, MC X, and MC XL systems. These threaded-shank burs are designed for wet milling of lithium disilicate, feldspathic ceramic, Vita Suprinity, and Celtra Duo. Seven configurations support single crowns, inlays, onlays, veneers, and anterior bridges.

The 20 configurations (longer TL21.5 cutting length) are suited for initial material removal or roughing, while the 12 and 12S configurations (TL13.5) are suited for finer detail and finishing. Cylinder, cylinder pointed, and step geometries provide different cutting profiles for specific milling stages.
These burs are not for milling metal, not for dry milling, and not compatible with CEREC 3 (M1.8 threaded shank).
These burs use an M3.5 threaded shank that screws directly into the Sirona CEREC MC, MC X, and MC XL spindle. They are not smooth collet-clamped shanks. The CEREC 3 system uses a different M1.8 thread, so these burs are not compatible with CEREC 3.
These burs are compatible with Sirona CEREC MC, MC X, and MC XL milling units. They are not compatible with CEREC 3, which uses an M1.8 threaded shank.
These diamond-coated burs are designed for wet milling of glass ceramics: lithium disilicate (IPS e.max), feldspathic ceramic, Vita Suprinity, and Celtra Duo.
The 12 and 12S configurations (TL13.5 cutting length) are typically used for finer detail and finishing work, while the 20 configuration (TL21.5 cutting length) is suited for initial material removal or roughing. Cylinder, cylinder pointed, and step geometries provide different cutting profiles for specific milling stages.
Watch for visible loss of diamond coating on the cutting surface, increased milling time, rougher surface finish on restorations, or chipping on the workpiece. These are signs the bur may need replacement.
These are SINCEN Dental aftermarket burs manufactured to fit Sirona CEREC MC, MC X, and MC XL systems. They use the same M3.5 threaded shank interface and are designed for the same glass ceramic materials.
No. These burs are designed for wet milling of glass ceramics. Dry milling is not recommended.
