Crosstech Carbide Straight Dome End Cross Cut Fissure Bur #1558 (FG, 1.2 mm) is a wider dome-ended cross-cut fissure bur for efficient cavity preparation in moderate to large posterior restorations. The 1.2 mm diameter allows faster material removal across a broader cutting path.

  • 1.2 mm diameter provides broader cutting width for larger Class I and Class II posterior preparations
  • Dome-rounded end prevents apical perforation and creates a smooth, rounded internal floor
  • Cross-cut flutes deliver aggressive, efficient dentinal removal with reduced clogging
  • Straight walls produce parallel cavity walls for predictable crown or direct restoration margins
  • FG friction-grip shank for standard high-speed handpieces
  • 10 per pack; autoclave sterilization compatible
