#35 x 25mm Pac-File NiTi Rotary File with 0.04 Taper – 6/Pack (FNT250435)

• An endodontic instrument set used for efficient root canal shaping and cleaning, containing 6 nickel-titanium (NiTi) rotary files with a 21mm length and a constant .04 taper

• Comparable to K3, Vortex, HyFlexNT, Endosequence

Uses

• Final Canal Preparation:

• Widens and finishes the mid-to-apical third of root canals after smaller files (sizes #20, #25, or #30) have established the shape

• Anatomically Balanced Reach:

• Optimally prepares standard-length anterior and posterior teeth requiring a 25mm instrument depth

• Calcified Path Clearance:

• Effectively moves through mineralized blocks and removes dentinal shavings in the apical zone

• Gutta-Percha Removal:

• Functions as an effective mechanical tool to clear old obturation materials during retreatment procedures

• Universal Workflows:

• Integrates effortlessly into standard crown-down or alternative constant-taper endodontic shaping techniques

• Universal Handpiece Integration:

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

Features

• Super-Elastic USA NiTi Alloy:

• Manufactured from premium American nickel-titanium alloy, providing maximum structural flexibility and strength

• 3-Fluted Cross-Section:

• Incorporates an efficient three-fluted design that enhances debris clearance and prevents debris packing

• Pre-Bend with No Rebound:

• Can be manually pre-bent by the operator to negotiate challenging curvatures or tight access points without snapping back straight

• Flute Unwinding Safety Mechanism:

• Under excessive torsional resistance, the file flutes structurally unwind rather than breaking instantly, offering a clear visual warning to discard the file

• Calibration & Color System:

• Built with integrated calibration rings for precision depth verification and a silver handle indicating a 0.04 taper

• Industry Compatibility:

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

Benefits

• High Breakage Resistance:

• Delivers exceptional protection against cyclical fatigue failures, drastically reducing the risk of broken fragments in the tooth

• Anatomy Preservation:

• Follows the natural curvature of the root morphology. This minimizes clinical complications like zipping, ledge formation, canal transportation, or apical wall perforation

• High Cutting Efficiency:

• The size #35 tip geometry paired with premium metallurgy yields rapid dentin cutting, minimizing chair time and enhancing patient comfort

• Direct Inventory Matching:

• Functions as a seamless clinical alternative to market-leading file sequences like K3, Vortex, HyFlexNT, and Endosequence without modifying handpiece settings
