Thread milling? Yes, that''s right!

Tübingen, 2014 – The new Walter Prototyp TC610/TC611 product family offers thread milling at its best. Two newly developed types of mill in two grades offer an increase in performance and process reliability that''s well worth a look.

Thread mills are not typical kinds of tools for mass production but rather for special applications. They are used in cases where processes such as thread cutting and thread forming don''t go far enough. In production scenarios like these, tool quality and process reliability assume an overproportional importance. And so it''s hardly a coincidence that the Tübingen tool specialist is entering the two equally new thread mills TC610 (thread depth = 1.5 x D) and TC611 (thread depth = 2.0 x D) in the race as the first representatives for its newly introduced and immediately available "Walter Supreme" product line.

"Supreme" means "highest" or "top". In the Walter range, "Walter Supreme" will from now on stand for, and quite clearly represent, the maximum possible quality, that''s to say the highest quality. Supreme tools can be used in cases where performance really matters. Because when very high cutting speeds, maximum tool life and the highest level of reliability are called for, particularly high-performance tools are also required. The Walter Supreme product line was designed specifically for such demanding applications and production objectives. The real thing in high-performance tools: In the Premier League for machining, they are the candidates for the "Champions League".

The two new TC610 and TC611 mills which have now been presented are available in two equally new grades: WB10RD and WJ30RC (B/J = substrate type, 10/30 = wear resistance, RD/RC = coating: TiALN/TiALN plus ZrN). Both variants can be universally used for materials from the ISO P, M, K, N and S groups. The difference lies in the differently balanced relationship between process reliability and tool life for different machining situations. The grades can also be clearly differentiated due to their appearance: WB10RD has a gold surface and WJ30RC a black surface.
