HyFlex EDM NiTi files are flexible and fracture resistant due to their manufacturing process using electric discharge machining: a potential is generated between the workpiece and the tool. The sparks generated cause the surface to melt and evaporate and make the files stronger and more fracture resistant, which makes it possible to reduce the number of files required and still preserve the root canal anatomy. Just like HyFlex CM files, HyFlex EDM files have controlled memory. The Max Curve Shaping set contains 1pc file size 15, taper 3%, 1pc file size 10, taper 5% and 1pc file size 20, taper 5%. All files are 25mm long.
