Diamond-coated milling burs with a φ4mm smooth shank for ARUM 4X Series and Axsys Versamill 5X-200 wet milling of glass ceramics. Designed for lithium disilicate (IPS e.max), feldspathic ceramic, Vita Suprinity, and Celtra Duo. Suited for single crowns, inlays, onlays, veneers, and anterior bridges in chairside or lab workflows. Available in four head diameters: φ0.6, φ1.0, φ1.5, and φ2.5.

φ2.5 and φ1.5 are suited for roughing and bulk material removal in glass ceramic blocks. φ1.0 and φ0.6 are suited for finishing passes, fine occlusal detail, and margin definition.
Not for metal, zirconia, or dry milling; only for wet milling of glass ceramics in ARUM 4X Series and Axsys Versamill 5X-200 machines with a φ4mm smooth shank collet.
They use a φ4mm smooth shank that is collet-clamped. This is not a threaded shank and not compatible with Sirona CEREC MC, MC X, or MC XL spindles, which require a proprietary M3.5 threaded shank.
They fit ARUM 4X Series and Axsys Versamill 5X-200 milling machines that accept a φ4mm smooth shank in a collet.
They are for glass ceramics: lithium disilicate (IPS e.max), feldspathic ceramic, Vita Suprinity, and Celtra Duo. They are not for metals, zirconia, or resin-based materials unless specified by the material manufacturer.
The φ2.5 and φ1.5 diameters are typically used for bulk material removal and roughing, while φ1.0 and φ0.6 are used for fine detail, occlusal anatomy, and margin finishing.
Watch for signs such as increased spindle load, chipping at margins, longer milling time, or visible loss of diamond coating on the cutting head. Replace when cut quality or edge definition declines.
These are aftermarket burs manufactured by SINCEN Dental specifically to fit ARUM 4X Series and Axsys Versamill 5X-200 machines with a φ4mm smooth shank collet.
No. These burs are designed for wet milling of glass ceramics. Dry milling may cause overheating, coating damage, and poor surface quality.
