#55 x 25mm Pac-File NiTi Rotary File with 0.04 Taper – 6/Pack (FNT250455)

• A nickel-titanium (NiTi) rotary file specifically designed for high-precision root canal shaping in endodontic procedures, featuring a #55 tip size, a .04 taper, and a 25mm length

• Comparable to K3, Vortex, HyFlexNT, Endosequence

Uses

• Wide Canal Shaping:

• Used for larger canals, such as maxillary centrals or the distal canals of mandibular molars

• Apical Enlargement:

• Ideal for clinicians who prefer a larger apical seat (#55) for better irrigation penetration

• Standard Length Procedures:

• The 25mm length is the “universal” size, reaching most roots effectively

• Universal Handpiece Integration:

• Operates reliably across all common rotary endodontic techniques designed for constant-taper sequences

Features

• American NiTi Alloy:

• Premium super-elastic material provides high flexibility and strength

• “Unwinding” Safety Feature:

• The file is engineered to visibly unwind when over-torqued, acting as a warning before the file snaps

• Constant .04 Taper:

• Ensures uniform shaping and allows for conservative dentin removal compared to .06 tapers

• Three-Flute Design:

• Optimized cross-section for maximum debris removal and reduced “screw-in” effect

• ISO Color-Coded:

• Marked with a Red handle/ring to signify the ISO #55 size

• Industry Compatibility:

• Comparable in function to systems like K3, Vortex, HyFlex NT, and Endosequence

Benefits

• Superior Fatigue Resistance:

• Offers up to 490% more resistance to breakage from cyclical fatigue than traditional NiTi files

• Anatomic Centering:

• Successfully follows the natural path of the canal, reducing the risk of transport or zipping the apex

• High Efficiency:

• Sharp cutting edges and efficient flute design reduce clinical chair time

• Predictable Results:

• The constant taper simplifies the selection of matching gutta-percha and paper points

• Direct System Compatibility:

• Serves as a seamless clinical alternative to market-leading file sequences like K3, Vortex, HyFlexNT, and Endosequence without needing adjustments to pre-set motor settings
