DCMT070204-FM4 WSM30S turning insert — Tiger‑tec Silver, FM4 chipbreaker | Walter Tools

DCMT070204-FM4 WSM30S is an indexable turning insert designed for productive machining of stainless steel and heat‑resistant superalloys, combining a robust grade with a heat‑resistant coating for demanding turning tasks.

• Tiger‑tec Silver coating for heat resistance
• WSM30S grade for stable cutting edges
• FM4 chipbreaker for reliable chip control
• Rhombus 55° geometry with 0.4 mm radius

Maximised process reliability through coating and grade

The combination of the Tiger‑tec Silver coating and the WSM30S carbide grade delivers a measurable increase in wear resistance and thermal stability during challenging turning operations. This technology is formulated to reduce flank wear and protect the cutting edge when machining tough alloys; as a result, machining cycles become more predictable and interruptions are reduced. The grade supports stable chip formation when working with stainless steel and demanding superalloys, which directly contributes to longer tool life and fewer regrinds—key factors for maintaining throughput and lowering overall production costs.

Geometry and clearance engineered for consistent part quality

The Rhombus 55° insert form with a 0.4 mm corner radius and 7° clearance provides a balance between cutting strength and accessibility for profile and finishing cuts. The acute geometry enables secure engagement in narrow grooves and interrupted cuts while the small radius helps maintain edge robustness for repeatable surface finishes. Clearances and edge geometry are designed to reduce rubbing and minimise heat generation at the cutting zone, which in turn supports dimensional accuracy and a more uniform surface texture on turned components.

Controlled chip formation for safe, efficient machining

The FM4 chipbreaker is optimised for medium to heavy turning operations in sticky and heat‑generating materials. Its land and pocket geometry assist in breaking chips into manageable segments and directing them away from the tool‑workpiece interface, lowering the risk of chip entanglement and workpiece damage. Reliable chip control not only improves operator safety but also reduces cycle interruptions and tool wear caused by irregular chip flow, thereby supporting continuous and efficient production runs.

Practical application and selection guidance

Designation and material suitability follow ISO conventions: the insert covers ISO groups M (stainless steel) and S (heat‑resistant superalloys / titanium), making it appropriate for components that demand thermal stability and edge security. For best results, select insert size and clamping suited to the toolholder and the intended depth of cut; the coded size and thickness should be matched to machine rigidity and part geometry.

FAQ

Is this insert suitable for machining stainless steel?
Yes. The DCMT070204-FM4 WSM30S insert is specified for stainless steel (ISO group M) and is formulated to reduce built‑up edge and improve edge life when machining stainless materials.

Which workpiece materials are covered by the WSM30S grade?
The WSM30S grade addresses both ISO groups S and M, meaning it is suitable for heat‑resistant superalloys and stainless steel where thermal stability and edge robustness are required.

What benefit does the FM4 chipbreaker provide in turning operations?
The FM4 chipbreaker promotes segmented chip formation and controlled evacuation, lowering the risk of chip entanglement and improving machining continuity for medium to heavy turning.

How does the 0.4 mm corner radius affect machining results?
A 0.4 mm corner radius increases edge strength for interrupted or semi‑finishing cuts while still allowing good surface finish; it is a compromise between robustness and achievable surface quality.

How can the Tiger‑tec Silver series be identified on the insert?
Tiger‑tec Silver is the specified coating technology for this range and is referenced together with the grade WSM30S on the DCMT070204-FM4 WSM30S marking; product labelling and catalogue data confirm the series and grade.
