DCMT11T304-MM4 WSM30S indexable turning insert — Walter Tools, Tiger·tec Silver, for stainless and superalloys

A DCMT11T304-MM4 WSM30S indexable insert designed for stable cutting in stainless steels and heat‑resistant superalloys, featuring a rhombic 55° geometry and a specialised MM4 chipbreaker.

• Tiger·tec Silver coated carbide grade WSM30S
• Optimised for stainless steel and superalloys
• Rhombic 55° insert with 7° clearance
• 0.4 mm corner radius for stable cutting
• MM4 chipbreaker for secure chip control

Maximise cutting reliability with a heat‑resistant grade

The WSM30S grade, developed within the Tiger·tec Silver family, is engineered for high thermal stability and reliable edge retention when machining tough workpiece materials. Thanks to the coating chemistry and substrate balance, the insert sustains a consistent cutting edge under elevated temperatures typical of stainless steels and superalloys, which reduces unexpected tool changes and improves process uptime. The measurable outcome is fewer interruptions and a more predictable production cycle.

Achieve consistent surface quality and predictable chip formation

The MM4 chipbreaker in this geometry promotes secure chip control during continuous and interrupted cuts, limiting built-up edge and minimising surface irregularities. With a 0.4 mm corner radius and 7° clearance, the geometry balances strength and versatility: the edge is robust enough for stable turning while still allowing favourable cutting forces for fine surface finishes. These characteristics translate directly into repeatable components and reduced rework.

Versatile geometry for demanding turning tasks

The rhombic 55° form offers a flexible approach to facing and turning operations, enabling positive cutting angles for improved feed capability and accessible cutting positions in complex setups. The 11 mm plate size and T3 thickness deliver a compact solution for tight toolholders while maintaining sufficient mass for heat dissipation. This combination makes the insert suitable for shops aiming to streamline tooling variants without sacrificing performance on challenging materials.

Integration into production and operational benefits

Incorporating these inserts into existing tool systems is straightforward and benefits are measurable: improved edge life, consistent chip control and reduced machine downtime. The insert’s tolerance class M and standard ISO designation ensure compatibility with common turning toolholders and CNC programmes. For customers seeking process optimisation, the technical data supports reliable cycle time estimates and easier parameter transfer between machines.

FAQ

What materials is this insert intended for?
The DCMT11T304-MM4 WSM30S insert is specified for stainless steels and heat‑resistant superalloys, where its coating and geometry enable improved thermal and edge stability.

How does the MM4 chipbreaker influence machining?
The MM4 chipbreaker promotes controlled chip formation and evacuation, reducing the risk of built‑up edge and improving surface consistency when using this Walter Tools insert.

What advantages does the 0.4 mm corner radius provide?
A 0.4 mm corner radius offers a compromise between edge strength and surface finish capability, helping to extend tool life while maintaining acceptable component quality.

Is the insert compatible with standard toolholders?
Yes; the ISO designation and tolerance class M make the insert compatible with common turning toolholder systems designed for rhombic 55° inserts.

Can the Tiger·tec Silver coating reduce tool changes?
The Tiger·tec Silver coating enhances thermal resistance and wear behaviour, which can lead to longer intervals between tool changes and more consistent production runs.
