Crosstech Acorn Diamond Bur (Extra Fine, Yellow, 2.3 mm) is an FG friction-grip diamond instrument for occlusal adjustment, crown and bridge contouring, and porcelain finishing. The distinctive acorn shape combines a rounded tip and bulging mid-body, providing smooth, controlled material removal on curved occlusal surfaces.

  • Extra Fine grit (yellow band) produces the smoothest surface finish for polishing and final refinement
  • Acorn geometry provides a smooth, rounded contact area ideal for occlusal adjustment of crowns and natural teeth without creating flat spots
  • Rounded tip and convex sides conform to natural tooth curvature for comfortable, controlled finishing
  • 2.3 mm diameter provides the working surface needed for efficient occlusal adjustment and surface contouring
  • Excellent for porcelain and zirconia adjustment and finishing in indirect restorations
  • FG friction-grip shank for use in standard high-speed handpieces
  • 5 per pack; use fine and extra fine grits for final porcelain surface smoothing before polishing
