Walter AG presents new Supreme blind hole taps
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.
