Ultra-fine diamond instruments engineered for sintered zirconia and lithium disilicate finishing. Coolant-optimized cutting pattern reduces heat buildup and produces a surface ready for the final polishing step.
Fully sintered zirconia and lithium disilicate are among the hardest materials in modern
restorative dentistry. Conventional finishing instruments generate excessive heat, create
surface defects, and wear rapidly. Diacool Ice addresses all three problems with a
diamond-bonded abrasive matrix and a coolant-channel geometry that actively draws air
and water through the cutting zone.
100,000–200,000 RPM with continuous air/water coolant
Exceeding the recommended speed range without adequate coolant may cause surface
micro-cracking in lithium disilicate. Always use adequate air/water spray.
| Grit Grade | ISO Color | Typical Use |
|---|---|---|
| Coarse | Red | Initial reduction, gross material removal |
| Medium | Blue | Contouring, milling mark removal |
| Fine | Yellow | Surface refinement, pre-polish prep |
| Extra Fine | White | Surface smoothing before polishing |
| Super Fine | Light Blue | Final surface preparation, high-gloss pre-stage |
Follow the Diacool Ice grit sequence for predictable surface quality. Each step
removes the scratch pattern from the previous instrument before moving forward.
Address occlusal contacts, reduce high spots, and establish gross contour after milling.
Refine anatomy, remove milling marks and tool path lines from CAD/CAM processing.
Smooth the surface uniformly. Eliminate the coarse scratch pattern from the blue instrument.
Create a uniform, scratch-free surface. The restoration is ready for polishing compounds.
Achieve a near-gloss surface. Proceed to Panther polishing system for mirror finish.
