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.Set contains 3 different OneFiles length 25mm, 1pc size 10, taper 5%, 1pc size 20, taper 5% and 1pc size 25. Recommended speed: 400rpm, max torque 2.5 N.cm.
