ABSTRACT:
A method of manufacturing endodontic files involves a chemical milling process to yield endodontic files having a desired taper. The process involves the steps of (a) providing a metallic rod having a cutting portion with a polygonal cross section; (b) torsioning the rod so as to form helical cutting surfaces in the cutting portion of the metallic rod; and (c) chemically milling the cutting portion of the rod so as to taper the cutting portion. The rod may be formed of any desirable metallic material, for example stainless steel or a nickel-titanium alloy.
