Threading

The TC430 Supreme thread former, specialized for ISO P materials, is for blind-hole and through-hole threads up to 3.5 x DN. Multiple coolant configurations are offered to best optimize performance—axial or radial coolant, with or without lubrication grooves. This HSS-E-PM thread former with AlCrN or TiN coating is available for both metric and metric fine threads. Grade designations are WW60AD andWW60EL.

The TC420 Supreme includes one configuration with chamfer form E, (M5–M16) for blind-hole threads up to  3.5 × DN, which uses an innovative combination of chamfer form E with axial internal coolant and without lubrication grooves. This new combination also improves the lubrication and, at the same time, reduces the torque by up to 30% – with a corresponding extension of tool life.

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. 

Walter has introduced the TC410 Advance HSS-E thread former, a versatile new TiN-coated threading tool that’s cost-effective even for small and medium batch sizes. It can be used universally for blind-hole and through-hole threads in most materials having a primary application in ISO material groups P, M and N and ISO K and S as a secondary application.

Tungaloy expands its TungThread line of indexable threading tools to include 11ER external threading inserts, as well as 8x8 mm and 10x10 mm square shank holders to accommodate the new inserts.

Scientific Cutting Tools has expanded the Single Point Thread Mill (SPTM) line with new sizes and lengths. The additional sizes include #5 and 7/16 for UN standards as well as larger M3 and M11 sizes for metric. The new extra long (XL) lengths were created for deeper threads. It is available in both UN and metric. All tools are available uncoated or with AlTiN coating.

Known for smooth cutting operations at high feed rates that reduce machining time, the Carmex Precision Tools Mini Spiral Mill-Thread line is now available in inch sizes, as well as metric. The spiral fluted toolholders, with internal coolant bore, hold from one to three inserts and are available in comparably small cutting diameters.
