ABSTRACT:
A completely corrosion resistant, high strength cutting tool such as an orthodontic wire cutter includes a stainless steel body having a pair of corrosion resistant alloy steel bonding tips brazed thereto. The tips are brazed to the body using a nickel alloy brazing foil at a brazing temperature of approximately 1900 degrees F. After a rough grinding to appropriate shape, the entire tool is heat treated in a process that heats the tool to an austenitizing temperature for the cutting tips that is about 2050 degrees F. and substantially above the brazing temperature to achieve a tip hardness of 62-67 Rc. Thereafter finish grinding, buffing, polishing and honing of the cutting edges completes the manufacture of the cutting tool.
