Increased Thread Turning Stability With New Walter TS

28 June 2025

Walter has added a new, high-performance tooling system to its portfolio with the new TS thread turning inserts and T1011 threading tools. The most striking special feature of the T1011 tool holder is a carbide pin in the rear asset of the cutting inserts.

This new feature prevents wear on the insert seat while the system's claw clamping ensures a stable hold for the TS indexable inserts. The toolholder can be fitted with four different indexable insert types in two highly wear-resistant Tiger-tec® Gold coatings. This includes the WMP22G grade that enables the highest possible cutting speeds, while the universal WMP32G grade has been designed for 70% of all applications, presenting maximum process reliability.

Both insert grades are suitable for ISO materials groups P and M and, as a secondary application, for ISO S, N and K. This ensures the new range is extremely versatile for a complete range of materials. The combination of Tiger-tec® Gold cutting inserts, innovative and stable clamping and the wear-protected insert surface ensures that tool life and thread precision are maximised.

The Sintered F5 and M5 geometries ensure very good chip-breaking properties. The F5 geometry produces very short chips on steel and stainless steel materials. In contrast, the M5 inserts enable a softer cut when applying lower cutting forces. The precision-ground single and multi-tooth inserts complete the system.

The latter reduces the number of thread infeeds, thus reducing the machining time by up to 40%. A new, customer-friendly two-pack also contributes to cost-effectiveness and sustainability. This minimises storage and procurement costs, especially where different threads have to be produced in small batch sizes.

Walter is initially offering the widely applicable TS system for the two most common insert sizes, TS16 and TS22, as well as various shank variants. This includes the addition of square shanks from 12 by 12mm to 40 by 40mm and C3 to C6 variants for Walter Capto™. From April, Walter has been adding new variants for internal threading to the programme.
