Shendiao 3.175mm Shank DLC-Coated Zirconia Milling Burs

SINCEN Dental Shendiao-compatible zirconia milling burs with a 3.175mm smooth shank and DLC (diamond-like carbon) coating. Designed for dry milling pre-sintered and multi-layer zirconia in Shendiao milling machines. Three head diameters—φ0.6mm, φ1mm, and φ2mm—cover finishing and roughing for single crowns, bridges, full-arch frameworks, and implant abutments.

Application

The φ2mm bur is suited for roughing and bulk material removal in large frameworks and bridges. The φ1mm bur is suited for semi-finishing and general shaping, while the φ0.6mm bur is suited for fine finishing, occlusal detail, and margin definition.

Limitations

These burs are not for milling metals, glass ceramics, composites, or for wet milling; they are only for dry milling of pre-sintered and multi-layer zirconia in Shendiao machines with a φ3.175mm collet.

Frequently Asked Questions

What shank type do these burs use?

These burs use a φ3.175mm smooth shank, clamped by a collet in Shendiao milling machines. They are not threaded shank burs.

Are these burs compatible with Sirona CEREC MC, MC X, or MC XL?

No. Sirona CEREC MC, MC X, and MC XL machines use a proprietary M3.5 threaded shank, not a φ3.175mm smooth shank. These burs are for Shendiao milling machines.

What does the DLC coating do for zirconia milling?

The DLC (diamond-like carbon) coating reduces friction and helps prevent zirconia dust from sticking to the tool during dry milling. This can reduce cutting force and improve chip evacuation.

Which head diameter should I choose for roughing vs finishing?

The φ2mm bur is generally used for bulk material removal (roughing). The φ1mm bur handles intermediate semi-finishing. The φ0.6mm bur is for fine details, tight occlusal anatomy, and margin areas.

How do I know when to replace these burs?

Replace the bur when you notice increased milling time, rougher surface finish, chipping on restoration margins, or visible wear on the cutting edges. Do not rely on a fixed number of units.

Are these OEM Shendiao burs?

No. These are aftermarket burs manufactured by SINCEN Dental, designed to fit Shendiao milling machines with a φ3.175mm collet. They are not original equipment manufacturer burs.

Can these burs mill wet zirconia or other materials?

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