Triple-Flex Files are triangular-bladed, stainless steel instruments designed for flexibility with integrity. The twisted flutes allow aggressive cutting and debris removal you demand without sacrificing the instrument’s inherent stability. Unlike round blades that have flutes ground in, these stainless steel endodontic files are highly breakage resistant, even in the most stressful situations. For performance and value you can depend on, our flexible endo file is the preferred choice.
