A method is provided for tipping the leading edge of teeth on a thread cutting tool with wear resistant material, without altering the basic size and shape of the tool, and without having to alter the way in which the teeth are cut. A plurality of veins of wear resistant material are hardened in slots in the tool body before axial flutes are cut into the tool body. When the flutes are cut, one side of the veins is exposed, and when the teeth are cut, they are thereby armored by the remainder of the exposed veins.
