With the new versions of the T2711 and T2712 thread milling cutters, Walter is offering its customers an indexable insert solution for small blind-hole and through-hole threads (≤ 2.5XDN) for thread sizes M16, M18 and UNC3/4. The new versions can be used in almost any material.
Flutes prevent the tool from being deflected by the chips produced, while the internal coolant ensures reliable chip removal. This makes the new T2711 and T2712 thread milling cutters ideal for high cutting speeds and feeds per tooth. The new cutters feature easy-cutting indexable inserts in the universal grade WSM37S which is available in two geometries. The D67 geometry can be used universally for maximum tool life, whilst the D61 geometry includes an anti-vibration land for excellent operational smoothness, even in challenging working conditions. Customers that already use the 06 size inserts in other thread milling cutters can also use these with the new T2711 and T2712 versions.
The new smaller T2711 and T2712 were developed specifically for cases where it's not cost effective for users to purchase expensive solid carbide threading tools, for example where production volumes are too low. The lower investment and tooling costs combined with the high flexibility of the new indexable insert thread milling cutters make them a cost-efficient alternative to solid carbide milling cutters.
This is because, unlike solid carbide milling cutters, the new tools do not need to be reconditioned. This means that only the cutting inserts need to be replaced. With smaller volumes, this compensates for the longer machining times while considerably improving cost-efficiency. With the T2711 and T2712, users can also machine different thread pitches and all ISO materials from groups P, M, K, N, S and H up to 55HRC. With this flexibility, the thread milling cutters reduce tool and inventory costs. Furthermore, the thread milling cutter boasts easy handling, for example infrequent radius corrections and high process reliability.
