• Reduced heat generation minimises risk of material damage.

Recommendations for Use

• Primary applications: Composite finishing and crown margin preparation.

• Equipment: Use with high-precision handpieces (max 10,000 RPM).

• Technique:

  • Start with coarser grits (e.g., 5862/6862) for bulk reduction.

  • Progress to fine/ultra-fine grits (8862/862UF) for final polishing.

  • Apply light pressure with intermittent water cooling.

• Safety: Wear protective goggles and a dust mask.

• Storage: Keep in a dry, sealed container to prevent corrosion.
