The solid carbide TC470 Supreme from Walter USA LLC (Waukesha, WI) takes an innovative approach to thread forming by combining a new geometry with more forming edges than comparable thread formers. A new coating and surface treatment increases tool life, productivity, and 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’s also shown good results in machining cast iron and aluminum.
Four variants are available: with or without lubrication grooves and/or internal coolant as well as with radial or axial coolant outlet, optimized for long and short threads. Dimension range of (metric) M3–M10 or (metric fine) M10 × 1–M16 × 1.5.
One of three designations for the company’s products, Supreme indicates the highest level of technology and performance available. Perform tools provide an economical solution with focused importance on price. Advance tools are efficiently balanced between price and performance.
