Straight Cross Cut Fissure Surgical Carbide Bur (#557L, 1.0 mm, Long) is an FGOS friction-grip oral surgery carbide instrument featuring an extended cutting head for deep access during complex oral surgical procedures. The long cross-cut design reaches areas that standard-length fissure burs cannot access.

  • Extended cutting head length provides deeper reach for sectioning impacted teeth and bone at posterior surgical sites
  • Cross-cut flute pattern maintains efficient chip evacuation even during deep, confined surgical cuts
  • 1.0 mm head diameter enables precise, narrow sectioning cuts in restricted posterior access areas
  • Preferred for deeply impacted mandibular third molar sectioning and posterior osteotomy cuts requiring additional depth
  • FGOS friction-grip oral surgery shank — extended shank length compatible with standard surgical handpieces
  • 10 per pack; single-use recommended to maintain sterility and peak cutting performance
