Crosstech Modified Bevel Cylinder Diamond Bur (Xtra Fine, Yellow, 1.6 mm) is an FG friction-grip diamond bur featuring a cylindrical body with a rounded bevel (KR modification) at the tip. The rounded chamfer creates a smooth shoulder-chamfer transition for marginal integrity in ceramic and PFM restorations.

  • Extra Fine grit (yellow band) produces the smoothest surface finish for final margin polishing, pre-impression refinement, and detail work
  • Rounded bevel (KR tip) creates a smooth shoulder-chamfer margin — reducing stress concentration and improving marginal fit in ceramic restorations
  • Cylindrical body produces parallel axial walls for controlled path of insertion
  • 1.6 mm diameter suited for premolar and molar crown preparations with chamfer margin design
  • FG friction-grip shank for use in standard high-speed handpieces
  • 5 per pack; suitable for shoulder-chamfer margin refinement in PFM and full-ceramic crowns
