#25 x 31mm Pac-File NiTi Rotary File with 0.04 Taper – 6/Pack (FNT310425)

• An endodontic instrument set used for efficient root canal shaping and cleaning, containing 6 nickel-titanium (NiTi) rotary files with a 31mm length and a constant .04 taper

• Comparable to K3, Vortex, HyFlexNT, Endosequence

Uses

• Ultra-Deep Canal Shaping:

• Designed for cleaning and shaping exceptionally long roots where 21mm or 25mm files fall short of reaching the apex

• Long-Tooth Endodontics:

• Essential for treatment of prominent canine and anterior teeth requiring extra physical reach

• Calcified Deep Canals:

• Safely bypasses calcification and cuts through debris deep within narrow canal pathways

• Deep Retreatment:

• Functions as an effective endodontic tool for reaching and extracting old gutta-percha fills from the deep apical third

• Rotary System Compatibility:

• Operates smoothly inside established rotational clinical procedures that utilize constant-taper files

Features

• Super-Elastic USA NiTi Alloy:

• Crafted from ultra-flexible, premium American nickel-titanium alloy to withstand significant stresses

• 31mm Working Shaft:

• Provides 6mm of additional length compared to a standard file, expanding procedural capability

• Pre-Bend Capability:

• The alloy permits pre-bending without rebounding to bypass difficult obstructions or enter constricted orifices

• 3-Fluted Safety Geometry:

• Uses an efficient 3-fluted cross-section alongside calibration rings to verify accurate depth control

• Visual Stress Indicator:

• Under excessive rotational torque, the flutes unwind instead of snapping instantly, serving as a warning to prevent instrument separation

• Silver Identifier Handle:

• Employs a silver-toned handle for immediate chairside identification of the 0.04 taper family

• Industry Compatibility:

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

Benefits

• Maximum Reach:

• Eliminates the clinical challenge of under-preparing exceptionally long canals by ensuring proper apex access

• High Fatigue Resistance:

• Offers superior structural protection against cyclical fatigue failures during prolonged rotational use

• Preserves Canal Integrity:

• Conforms reliably to natural root curvature, helping clinicians avoid structural errors like canal ledgering, transportation, or wall perforation

• Seamless Drop-In Replacement:

• Matches the operational parameters of market standards like K3, Vortex, HyFlexNT, and Endosequence
