FQ .04 ISO 45 25mm 6pcs

Heat-treated nickel-titanium rotary endodontic file system designed for efficient and minimally invasive root canal preparation. Features a variable taper core with double S cross-section for maximum flexibility and cutting efficiency, allowing the file to follow complex canal anatomy even in severely curved canals. The pre-bendable design reduces the risk of ledging and zipping while providing enhanced resistance to cyclic fatigue and instrument separation. Package contains 6 files of 25mm length.
