Material Guide: Which Bur for Which Block?

Different materials require specific bur coatings and cutting geometries. Using the wrong bur type on a material causes poor surface finish, shortened tool life, or restoration fit issues.

Lithium Disilicate (e.max CAD)

Use electroplated diamond burs with micro-grain matrix. Coarse grit for roughing, fine grit for finishing. All our glass ceramic burs are optimized for e.max.

Zirconia (Pre-sintered)

Requires special-coated burs to withstand abrasive zircon dust. Engineered to precisely mill enlarged frameworks accommodating the ~25% sintering shrinkage. Contact us for zirconia bur specs for your machine model.

PMMA / Wax

Use resin-specific burs. Diamond burs are not recommended — they clog on soft materials and wear unevenly.

Metal (CoCr / Titanium)

Requires tungsten carbide burs with specialized geometries. Do not use diamond burs on metal.

Frequently Asked Questions

Q: Which burs fit my Sirona CEREC MC XL / MC X / MC?

Sincen offers 7 Sirona-compatible glass ceramic burs tailored for CEREC MC XL / MC X / MC: Step Bur (12S, 12, 20) and Cylinder Pointed Bur (12S, 12 EF, 20) and Cylinder Bur (12 EF). All are engineered with an electroplated diamond micro-grain matrix optimized for high-precision milling of lithium disilicate blocks.

Q: Can I use the same burs on CEREC MC XL / MC X / MC and inLab MC X5?

No. These models use different shank dimensions and the burs are not cross-compatible. Always select the correct bur set for each specific machine model.

Q: What materials can I mill with Sirona burs?

Our Sirona-compatible burs support: Glass Ceramic — electroplated diamond burs with micro-grain matrix
Zirconia — diamond-coated burs (contact for specs)
