Sirona inLab MC X5 Zirconia Milling Burs with DLC Coating

SINCEN Dental offers DLC-coated zirconia milling burs for the Sirona inLab MC X5 dry milling system. Designed for pre-sintered and multi-layer zirconia, these burs support single crowns, bridges, full-arch frameworks, and implant abutments. Available in three head diameters—φ0.5mm, φ1mm, and φ2.5mm—each with a φ3mm smooth shank for collet clamping.

Application

The φ2.5mm head diameter is suited for roughing and bulk material removal. The φ1mm head diameter is suited for intermediate contouring, while the φ0.5mm head diameter is suited for fine finishing and small features.

Limitations

These burs are not for metal, glass ceramic, fully sintered zirconia, or wet milling applications.

Frequently Asked Questions

What shank type do these burs use for the Sirona inLab MC X5?

These burs use a φ3mm smooth shank that is collet-clamped. This is different from the proprietary M3.5 threaded shank used on CEREC MC, MC X, and MC XL machines, and the M1.8 threaded shank used on CEREC 3.

What is the DLC coating and why is it used on these burs?

DLC (diamond-like carbon) is a hard, low-friction coating. On these burs, it reduces friction during dry milling of pre-sintered and multi-layer zirconia, helping to manage heat and material adhesion without coolant.

Which machines are these burs compatible with?

These burs are specified for the Sirona inLab MC X5. They are not intended for CEREC MC, MC X, MC XL, or CEREC 3 machines, which require threaded shanks.

How do I choose between the φ0.5mm, φ1mm, and φ2.5mm head diameters?

The φ0.5mm variant is suited for fine detail and small features. The φ1mm variant handles medium contouring and intermediate material removal. The φ2.5mm variant is used for bulk material removal and roughing.

How can I tell when a bur is worn?

Watch for changes in milling sound, increased edge chipping on the zirconia, visible loss of coating on the cutting edges, or reduced dimensional accuracy of the milled restoration. Replace the bur when these signs appear.

Are these OEM Sirona burs or aftermarket?

These are SINCEN Dental aftermarket burs manufactured to fit the Sirona inLab MC X5. They use the same φ3mm smooth shank interface and are intended for the same dry zirconia milling applications.

Can these burs be used for wet milling or for other materials?

These burs are specified for dry milling of pre-sintered and multi-layer zirconia only. They are not intended for wet milling, metals, glass ceramics, or fully sintered zirconia.
