2-in-1 Pre-Sintered Zirconia Grinding Polishing Bur Disc Dental Lab Dual Grit Crown Bridge Restoration Tool 15000RPM

Application

Pre-sintered & green-state zirconia

Recommended speed
15,000–20,000 RPM

Shank
HP · 2.35 mm diameter

Grit system
Medium (grey) + Fine (white)

2-step dual-grit workflow

1
Step 1 — Grinding & shaping (grey-black · medium-coarse grit)
Removes bulk material and refines contour. The medium-coarse abrasive segment efficiently shapes the restoration without causing micro-cracks in the fragile pre-sintered body.
2
Step 2 — Polishing & finishing (white · fine grit)
Achieves a smooth, polished surface in a single pass. The fine-grit segment simplifies the finishing step before final sintering, reducing overall lab time.

Usage: for grinding and polishing zirconia workpiece

Product features

* Dual-grit abrasive body combines medium-coarse (grey) and fine (white) zones in one bur — no tool change required between grinding and polishing.

* Specially developed for the lower strength of pre-sintered zirconia (green-state / bisque-fired), preventing chipping or fracture during shaping.

* No colour pigments used — zero contamination risk to zirconia, preserving translucency and shade accuracy after final sintering.

* Rapid polished finish — simplifies post-sintering finishing steps by achieving a smoother pre-sintered surface.

* Suitable for crowns, bridges, inlays, onlays and other full-contour zirconia restorations.
