Thread Mills cut a thread using helical interpolation. Helical interpolation involves moving three axes simultaneously. The X and Y axes move in a circular motion while the Z axis moves in a linear motion. This allows Thread Mills to cut both right and left hand threads and to produce a variety of thread sizes (of the same pitch). All Thread Mills are made from premium sub-micron carbide (except for T15 Powdered Metal Thread Mills) and are stocked with or without a TiALN coating. They are ground on state-of-the-art CNC tool and cutter grinders and have been engineered for high performance. Programming assistance is available.
