DCMT070204-FM4 WSM01 indexable turning insert, Tiger‑tec Silver grade for stainless steel and superalloys — Walter Tools

The DCMT070204-FM4 WSM01 is an indexable turning insert engineered for machining stainless steel and heat‑resistant superalloys, combining a coated carbide substrate with a chipbreaker geometry for controlled chip formation.

• Tiger‑tec Silver coating for high thermal resistance
• WSM01 grade optimised for stainless steel and superalloys
• Rhombic 55° form with 7° relief for stable cutting
• FM4 chipbreaker and 0.4 mm corner radius for finish

High‑temperature performance that secures chipflow and productivity

The combination of the Tiger‑tec Silver coating and the WSM01 grade provides reliable heat resistance and a stable cutting edge when machining materials that tend to work‑harden or produce long, stringy chips. The coated carbide substrate supports consistent wear behaviour under thermal load, reducing the need for frequent insert changes and helping to maintain average cycle times. For production environments where material batches vary, the insert’s metallurgy is chosen to sustain process stability across both stainless steel and superalloys, limiting unexpected downtime and improving repeatability.

Geometry optimised to improve surface finish and reduce rework

The insert’s rhombic 55° shape combined with 7° relief gives a predictable engagement angle that reduces cutting forces during transverse and light turning operations. The FM4 chipbreaker is designed to fragment and evacuate chips effectively, which supports steady machining even when thermal conductivity of the workpiece is low. The 0.4 mm corner radius balances edge strength and fine surface finish, making the insert suitable for semi‑finishing and finishing passes where control of tool marks and tolerance achievement is essential for downstream operations.

Coating and substrate technology that extend tool life

A coated carbide construction provides improved wear resistance and thermal stability compared with uncoated alternatives. The Tiger‑tec Silver layer acts as a thermal barrier and reduces adhesion of workpiece material to the cutting edge, supporting longer edge life in challenging alloys. This technical combination increases process security in series production, where consistent edge performance translates directly into fewer interruptions, lower scrap rates and measurably higher productivity.

Easy integration into turning systems and predictable results

The design of this turning insert aligns with standard toolholder systems for the DCMT 07 family and facilitates quick index changes and re‑identification in toolrooms. The DCMT070204-FM4 WSM01 insert from Walter Tools delivers a reproducible cutting geometry and clear specification for quality assurance routines, which simplifies tool inventory management and makes process documentation straightforward. When paired with appropriate feeds and speeds, the insert supports controlled chip removal and consistent surface quality, contributing positively to overall manufacturing throughput.

FAQ

What materials is this insert suitable for?
The DCMT070204-FM4 WSM01 is intended for stainless steel (ISO group M) and heat‑resistant superalloys/titanium (ISO group S), where edge stability and thermal resistance are required.

Which chipbreaker and corner radius are specified?
The insert is supplied with an FM4 chipbreaker and a 0.4 mm corner radius, optimised for controlled chip formation and improved surface finish on semi‑finishing and finishing passes.

How does the Tiger‑tec Silver coating affect tool life?
The Tiger‑tec Silver coating reduces adhesion and improves thermal stability, which helps to extend edge life and maintain process security when machining materials that generate high temperatures at the cutting zone.

Is the geometry suitable for finishing operations?
Yes. The rhombic 55° form together with the 0.4 mm corner radius and 7° relief provides a balance of edge strength and low cutting force suitable for fine turning and achieving consistent surface quality.

What does tolerance class M mean for machining precision?
Tolerance class M indicates the plate’s dimensional tolerance suited for standard production tolerances; it supports repeatable positioning in the toolholder and predictable cutting behaviour.
