Yunjia Compatible Zirconia Milling Burs

DLC-coated milling burs designed for Yunjia milling machines, engineered for dry milling of pre-sintered and multi-layer zirconia. Available in three configurations with φ4mm smooth shanks for collet clamping, these burs support precise machining of single crowns, bridges, full-arch frameworks, and implant abutments.

Application

φ2mm is suited for roughing and bulk material removal in large frameworks and full-arch restorations. φ1mm handles semi-finishing and medium detail, while φ0.6mm is intended for fine finishing, occlusal anatomy, and precise margin definition.

Limitations

These burs are not for milling metals, glass ceramics, or any material other than pre-sintered and multi-layer zirconia, and are not for wet milling.

Frequently Asked Questions

What shank type do these Yunjia compatible zirconia burs use?

These burs use a φ4mm smooth shank (collet-clamped), not a threaded shank. They are not compatible with Sirona CEREC MC/MC X/MC XL machines, which require a proprietary M3.5 threaded shank, or CEREC 3, which uses M1.8.

Which Yunjia machines are these burs compatible with?

They are designed for Yunjia milling machines that accept φ4mm smooth shank tools with collet clamping. Always verify your machine's tool holder specification before ordering.

What materials can these burs mill?

These burs are intended for dry milling of pre-sintered zirconia and multi-layer zirconia. They are not suitable for metal, glass ceramics, or wet milling applications.

How do I choose between φ0.6mm, φ1mm, and φ2mm?

Use φ2mm for bulk material removal and roughing large frameworks; φ1mm for semi-finishing and medium-detail areas; φ0.6mm for fine finishing, tight occlusal anatomy, and delicate margin lines where precision is critical.

How do I know when to replace these burs?

Monitor for visible wear signs: increased edge chipping on milled zirconia, rougher surface finish, higher spindle load, or longer milling times. Replace when cut quality degrades or coating shows visible damage. No fixed unit count is specified.

Are these OEM Yunjia burs or aftermarket?

These are aftermarket burs manufactured by SINCEN Dental, designed to be compatible with Yunjia milling machines. They are not original Yunjia parts but are produced to fit the same φ4mm collet interface.

Can these burs be used for wet milling?

No. These burs are specified for dry milling only. Using them with coolant or in wet milling machines may affect coating performance and is outside the intended application.
