Stainless steel files are not elastic, while nickel-titanium files are flexible and are more suitable for curved root canals.
Stainless steel files have more cutting force, but less breaking resistance. Compared with the NITI-TITANIUM files that have less cutting force, the files are not easy to break, which is safer. However, the cutting force of nickel-titanium files is weaker and less efficient than stainless steel files.
Increased angular rotation reduces fracture compared to stainless steel
Ni-Ti decreases zipping and stripping
K-Files are designed to clean and shape root canals. It gives the users a smooth tactile sense inside the canal during instrumentation.
Ni-Ti shaft is made of premium nickel-titanium with 5 times the flexibility compared to stainless steel files
Ni-Ti has 10 times the stress resistance compared to stainless steel files
Produces smooth and progressive enlargement of root canal
Ni-Ti follows the existing canal path and has memory so there is no need to pre-bend the files
K file is available in stainless steel & Titanium
