Crosstech-Carbide Bur, FG, # 1558, Straight Dome End Cross Cut Fissure, 1.2 mm, 10/Pk, FG1558-10

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
