SINCEN Dental Roland compatible zirconia milling burs are DLC-coated cutting tools designed for dry milling of pre-sintered and multi-layer zirconia in Roland milling machines. They are supplied in three head diameters—φ0.6mm, φ1mm, and φ2mm—with a φ4mm smooth collet-clamped shank, covering single crowns, bridges, full-arch frameworks, and implant abutments.

| φ0.6mm | φ0.6×TL10×φ4×L50 | 0.6 | 10 | 4 | 50 | 1 |

The φ2mm head diameter is suited for roughing and bulk material removal on large frameworks and full-arch restorations. The φ1mm head is suited for general contouring of crowns and bridges, while the φ0.6mm head is suited for finishing fine details such as occlusal anatomy, margin lines, and implant abutment contours.
These burs are not for milling metals, glass ceramics, or fully sintered zirconia, and they are not intended for wet milling.
All three variants use a φ4mm smooth shank that is collet-clamped in the milling machine spindle. This is the shank interface specified for Roland milling machines.
No. Sirona CEREC MC, MC X, and MC XL machines require a proprietary M3.5 threaded shank, and CEREC 3 requires an M1.8 threaded shank. These SINCEN burs use a φ4mm smooth shank and are intended for Roland milling machines only.
The φ2mm head is suited for bulk material removal on larger frameworks and full-arch restorations. The φ1mm head is a general-purpose diameter for crowns and bridges. The φ0.6mm head is intended for fine detail areas such as occlusal anatomy, margin lines, and implant abutment contours.
DLC stands for diamond-like carbon. On these burs, the DLC coating is applied to the cutting surfaces to reduce friction during dry milling of pre-sintered and multi-layer zirconia.
Monitor cutting behavior and restoration quality. Wear signs include increased spindle load, rougher milled surfaces, chipping on thin zirconia margins, visible rounding or dulling of the cutting edges, and dimensional inaccuracies in milled restorations. Replace the bur when these signs appear.
These burs are specified for dry milling in a lab environment. Do not use them with liquid coolant unless the machine manufacturer explicitly permits it for this tool type.
These are SINCEN Dental aftermarket burs manufactured to fit Roland milling machines. They are not produced by Roland. The φ4mm smooth shank matches the Roland spindle interface, but the bur is a SINCEN product.
