#50 x 31mm Pac-File NiTi Rotary File with 0.04 Taper – 6/Pack (FNT310450)

• A nickel-titanium (NiTi) rotary file specifically designed for high-precision root canal shaping in endodontic procedures, featuring a #50 tip size, a .04 taper, and a 31mm length

• Comparable to K3, Vortex, HyFlexNT, Endosequence

Uses

• Extra-Long Canal Shaping:

• Specifically designed for long roots (like canines) where standard 21mm or 25mm files are too short

• Posterior Access:

• The 31mm length provides better visibility and clearance when using a handpiece in the back of the mouth

• Deep Retreatment:

• Used to remove filling material from the apical third of very long root canals

• Universal Handpiece Integration:

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

Features

• Extended 31mm Shaft:

• Provides maximum reach for non-standard clinical cases

• Super-Elastic NiTi:

• Made from high-quality American nickel-titanium for superior flexibility

• Fail-Safe Design:

• The file is engineered to “unwind” rather than snap when it encounters excessive torque

• Constant .04 Taper:

• Ensures a predictable, uniform shape throughout the canal preparation

• ISO Color-Coded:

• Features a yellow shank/handle marker to signify the #50 size for quick identification

• Industry Compatibility:

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

Benefits

• Canine Specialist:

• Essential for maxillary canines, which often exceed 25mm in total length

• High Breakage Resistance:

• Offers nearly 5x the cyclical fatigue resistance of conventional rotary files

• Anatomic Centering:

• Maintains the natural curvature of the canal, minimizing the risk of “zipping” or transporting the apex

• Tactile Feedback:

• The alloy provides a balance of stiffness and flexibility, allowing the clinician to “feel” the canal anatomy even at 31mm

• 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
