Abstract
A tool for shaping wax and wax-like substances has a handpiece containing an electrical connector for connection to a source of electrical power and an opening in which an electrically heated tool tip is removably mounted for the convenient interchange of tips. The tool tip is held in a fixed predetermined position in the opening by ridges in the opening interlocked with complementary notches on the tip and is removably mounted within the opening in electrical connection with the connector. A cooling air gap is formed between the outer surface of said tip and the inner surface of said opening by the interlocked ridges and notches to prevent overheating of the handpiece. The tip comprises two spaced apart electrically conductive parallel wires which are connected at one end to form a continuous tip which defines a confined air gap of a defined configuration which is suitable for holding and shaping wax.
