DCMT11T302-MM4 WSM30S turning insert — Rhombic 55°, Tiger·tec Silver by Walter Tools

DCMT11T302-MM4 WSM30S is a precision turning insert designed for reliable machining of stainless steels and heat‑resistant alloys in production environments

• Tiger·tec Silver coating for extended tool life
• Grade WSM30S for stainless steels and superalloys
• Rhombic 55° insert with 0.2 mm corner radius
• MM4 chipbreaker for controlled chip formation

High performance for stainless and high‑temperature alloys

The DCMT11T302-MM4 WSM30S indexable insert combines a wear‑resistant Tiger·tec Silver coating with a specialised WSM30S cemented‑carbide grade to tackle materials that tend to work‑harden or generate elevated cutting temperatures. The geometry and coating work together to reduce built‑up edge and support a stable cut, which translates into fewer interruptions and improved process reliability. This makes the insert particularly suitable where consistent surface quality and repeatable tool life are required when machining stainless steels and heat‑resistant superalloys.

Reliable chip control and edge stability for productive turning

The MM4 chipbreaker and Rhombic 55° form are engineered to produce predictable chips and to ease evacuation in continuous turning. With a 0.2 mm corner radius and a 7° clearance angle, the insert balances edge strength and fine finishing capability: the corner supports durable performance under interrupted cuts while the clearance angle reduces rubbing and heat build‑up. The result is controlled chip formation, longer time between indexings and more stable component tolerances, benefiting throughput and reducing secondary operations.

Practical integration and application guidance

This turning insert is supplied in the standard DCMT format and fits common toolholders for negative‑style indexable turning systems. The T3 plate thickness and the M tolerance class ensure repeatable seating and concentricity when mounted in a suitable holder; correct clamping reduces vibration and extends service life. For machining stainless materials, consider moderate cutting speeds and adequate coolant strategies to exploit the WSM30S grade’s thermal resilience while maintaining consistent finish and dimensional stability.

FAQ

What materials is this insert intended for?
The DCMT11T302-MM4 WSM30S insert is formulated for machining stainless steels and high‑temperature superalloys (ISO groups S and M).

How does the Tiger·tec Silver coating help in practice?
The Tiger·tec Silver coating improves wear resistance and thermal stability, which supports longer tool life and consistent surface finish during prolonged stainless‑steel turning.

Which chipbreaker is fitted and why does it matter?
The insert uses an MM4 chipbreaker designed for predictable, easily evacuated chips, reducing interruptions and improving process safety.

Is this insert compatible with standard DCMT toolholders?
Yes, the DCMT geometry and T3 thickness conform to common negative insert holders; proper clamping and seating to the M tolerance class ensure repeatable results.
