The small but mighty alternative to solid carbide

By Bhalchandra Chorghade, Editor, CNCTimes.com

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 (≤ 2.5 × DN) in dimensions of M16, M18 and UNC3/4. It can be used in almost any material. Flutes prevent the tool being deflected by the chips produced, while the internal coolant ensures reliable chip removal.

This makes the tool ideal for high cutting speeds and feeds per tooth. The milling cutter features easy-cutting indexable inserts from grade WSM37S which are available in two geometries: As D67, which can be used universally for maximum tool life and as D61, with anti-vibration land for excellent operational smoothness, even in challenging working conditions. Customers who already use the 06 size inserts in other milling cutters can also use these with the T2711 and T2712 versions.

The "little" T2711 and T2712 were developed specifically for cases where it's not worth it for users to purchase expensive solid carbide threading tools, for example because their volumes are too low. The lower investment and tool costs and 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 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 55 HRC). Thanks to these two capabilities, the thread milling cutter reduces tool and storage costs. What's more, the thread milling cutter boasts easy handling (for example infrequent radius corrections) and high process reliability.
