Long Reach Thread Mills
Long Reach Thread Mills have three teeth and a helical flute that provide reduced side cutting pressure. The first tooth roughs, the second and third finish. This allows for the efficient cutting of extremely deep threads in small sizes. These tools cut internal threads only
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 arc made from premium sub-micron carbide (except for TI5 Powdered Metal Thread Mills) and arc stocked with or without aTiALN 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.
