The hob cutter, commonly known as a hob, is a specialized cylindrical cutting tool utilized in a machining process called hobbing to precisely form gear teeth, splines, and sprockets.
A hob cutter, or simply hob, is a highly precise, specialized cylindrical cutting tool designed for hobbing, a machining process used to generate gear teeth, splines, sprockets, and other similar toothed profiles. Its unique helical cutting teeth, arranged around the circumference, progressively remove material from a rotating workpiece to create the desired form. Hob cutters are typically manufactured from high-performance materials to withstand the demanding conditions of gear cutting, including high cutting forces and temperatures.
