Walter has introduced the TC470 Supreme solid carbide thread former, an innovative approach to thread forming that combines a new geometry with more forming edges than comparable thread formers. The new thread former features a new coating and surface treatment for better tool life, higher productivity, and increased process reliability in large batch and high-volume production while achieving a lower cost per thread.

The exceptionally smooth yet hard coating improves surface quality, which, in turn, significantly reduces torque requirements. Intended for blind hole and through hole threads and thread depths up to 3.5 x DN in steel, it has also shown good results in machining cast iron and aluminum. The TC470 Supreme is offered in four variants: With or without lubrication grooves and/or internal coolant, as well as with radial or axial coolant outlet, optimized for long and short threads.

The TC470 thread former is available in dimension range of (metric) M3 to M10 or (metric fine) M10 x 1 to M16 x 1.5.

The Supreme designation indicates the highest level of technology and performance available. The Supreme lineup of products is one of three designations to Walter product technology – Preform, Advance, Supreme.

The Perform tools are products that provide an economical solution with focused importance on price. The Advance tools are products which are efficiently balanced between price and performance.
