Powerful in all steel materials

With the TC120, TC121 and TC122 product range, Walter is presenting three new blind hole taps in the Supreme line specially developed for machining steel materials.

The taps cover all tensile strengths from 300 to 1400 N/mm2: The TC120 Supreme with a 45° helix angle makes it possible to reliably produce threads up to 3 × DN in soft and medium-strength steels. The TC120 Supreme stands out thanks to its partial TIN coating in the chamfer section, which increases the tool life, a special geometry to prevent bird nesting and the extra-long threaded part to reduce fractures. The TC121 Supreme is suitable for threads up to 2.5 × DN in steels with medium tensile strengths between 800 and 1250 N/mm2. The tap with a 40° helix angle and a geometry which ensures tightly rolled chips combines maximum tool life with a high level of process reliability.

The TC122 Supreme with a 15° helix angle ensures a long tool life in medium-strength to high-strength ISO P materials. It can produce thread depths up to 1.5 × DN without internal cooling, while up to 2.5 × DN is possible with internal cooling. With internal cooling, the specialist in high-strength steels is increasing process reliability by flushing out the chips. The hardened tap features a special geometry which breaks the chips so that they are extremely short, as well as a TiCN coating. As a "package", the three HSS-E and HSS-E-PM taps offer particular benefits for users who want to machine a wide range of steel materials – for example in general mechanical engineering. As individual tools, they impress in their specific range of applications.
