Crosstech Inverted Cone Diamond Bur (Coarse, Green, 1.2 mm) is an FG friction-grip diamond instrument for creating undercuts, retention grooves, and accessing deep subgingival preparation areas. Its wider tip relative to the body allows undercutting and flat-floor preparation in locations where standard bur shapes cannot reach effectively.

  • Coarse grit (green band) provides efficient material removal for initial reduction and primary shaping
  • Inverted cone geometry (wider at the tip) enables undercutting and retention groove preparation not achievable with standard cylindrical or tapered burs
  • Effective for creating retention form in inlay and onlay preparations where diverging walls are required
  • 1.2 mm tip diameter provides adequate cutting width for premolar and molar preparation needs
  • FG friction-grip shank compatible with all standard high-speed handpieces
  • 5 per pack; essential addition to any bur kit requiring undercut or retention groove preparation
