Crosstech Carbide Bur #245 (FG, Amalgam Prep, 0.8 mm) is a slim tapered cross-cut fissure bur designed for Class I and Class II amalgam cavity box form preparation. Its narrow 0.8 mm tip cuts clean, precise walls for reliable amalgam retention.

  • Tapered cross-cut fissure geometry creates flat-floored box forms with defined proximal walls for amalgam retention
  • 0.8 mm tip width allows entry into tight proximal contacts without excessive tooth destruction
  • Cross-cut flutes provide aggressive, efficient dentinal cutting with smooth walls
  • FG friction-grip shank fits standard high-speed handpieces
  • 10 per pack for consistent clinical availability
  • Autoclave-safe stainless steel shank and precision-ground carbide head
