Usage Tips That Apply Across Materials

Regardless of material or instrument type, these fundamental technique principles
will maximize performance and instrument life.

• 
  Use appropriate RPM. Most Wagner Precision instruments are optimized for
  25,000–35,000 RPM for ceramic and zirconia. Refer to individual product sheets for
  material-specific speed recommendations.
  
• 
  Apply light, consistent pressure. Excessive pressure generates heat,
  accelerates wear, and risks micro-fracture in ceramic materials. Let the abrasive do
  the work.
  
• 
  Use coolant or air when indicated. Sintered zirconia and lithium disilicate
  benefit from air or water cooling. The Diacool Ice system is specifically engineered
  for coolant-assisted cutting.
  
• 
  Follow the grit sequence. Moving through coarse, medium, fine, and
  extra-fine stages in order removes previous scratch depth systematically. Skipping steps
  extends total finishing time rather than shortening it.
  
• 
  Clean instruments between uses. Use a soft brush or ultrasonic cleaning
  to remove debris between cases. Loaded instruments cut less efficiently and generate more heat.
  
• 
  Keep instruments moving. Stationary contact concentrates heat. A gentle
  circular or figure-eight motion distributes load and improves surface uniformity.
  
• 
  Inspect before each use. Worn abrasive elements or damaged shanks should
  be replaced. A degraded instrument creates an unpredictable cutting surface.
  
• 
  Match instrument to substrate hardness. Coarser grits for harder, more
  resistant materials; finer grits for softer ceramics and esthetically critical surfaces.
