Crosstech-Carbide Bur, FG, # 1557, Straight Dome End Cross Cut Fissure, 1.0 mm, 10/Pk, FG1557-10

Crosstech Carbide Straight Dome End Cross Cut Fissure Bur #1557 (FG, 1.0 mm) combines the dome-ended tip of a rounded fissure bur with cross-cut flutes for faster, more aggressive dentinal cutting. Ideal for cavity preparation where efficiency and a smooth internal floor are both required.

  • Dome-rounded end creates a smooth, rounded cavity floor while preventing apical gouging
  • Cross-cut flutes increase cutting efficiency and speed compared to plain fissure designs
  • 1.0 mm diameter suited for Class I and Class II cavity box forms
  • Combination of dome tip and cross-cut pattern reduces need for multiple bur changes during preparation
  • FG friction-grip shank compatible with all standard high-speed handpieces
  • 10 per pack; autoclave-safe for routine sterilization
