Walter’s new TC420 Supreme thread for universal use is an HSS-E-PM thread former with a high number of forming edges, produces high cutting speeds with up to 30 per cent less torque.
The TC420 Supreme includes one configuration with chamfer form E, (M5–M16) for blind-hole threads up to 3.5 × DN, which uses a combination of chamfer form E with axial internal coolant and without lubrication grooves.
This new combination improves lubrication and reduces torque.
The TC420 Supreme metric version has radial internal coolant for blind-hole and through-hole threads.
These new thread formers show higher break-out resistance under dynamic load compared with other threading techniques. They are available for medium to large batch sizes with and without lubrication grooves, axial or radial internal coolant, or without internal coolant.
Tool coating options are either TiN coating (WW60AD grade) or TiCN (WW60BA). Typical areas of application include general metalworking as well as the automotive and energy industries, for ISO materials P, M, K, N, and a secondary use in ISO S materials.
