DCMT070208-MM4 WMP20S — Indexable turning insert, Rhombic 55° / 0.8 mm nose radius, Walter Tools

The DCMT070208-MM4 WMP20S is an indexable turning insert designed for machining stainless steels under medium to robust conditions, combining a coated-carbide grade with a chipbreaker tuned for reliable chip formation.

• Tiger·tec Silver coating for secure chip control
• Optimised for stainless steel (ISO group M)
• Rhombic 55° form with 0.8 mm nose radius
• MM4 chipbreaker for stable cutting performance

Predictable productivity for stainless steel applications

The combination of the Tiger·tec Silver coating and the WMP20S grade targets the specific challenges of machining stainless steel (ISO group M). The coating supports heat resistance and wear protection while the substrate provides mechanical strength; together they promote stable chip formation and reduced risk of built-up edge. This results in fewer interruptions, longer tool life and a more predictable machining process, which helps to improve component throughput and reduce rework in batch production.

Geometry and chip control that protect efficiency

A Rhombic 55° insert form with a 0.8 mm nose radius and a 7° clearance angle gives a balance between cutting strength and surface finish. The MM4 chipbreaker is engineered to manage swarf behaviour in tougher, sticky materials, ensuring that chips evacuate cleanly and the cutting edge remains stable. For shops aiming to maintain consistent tolerances and surface quality, this geometry translates directly into fewer tool changes and lower per-part machining costs.

Format clarity for easy integration and handling

The designation DCMT070208-MM4 decodes as a rhombic 55° insert in size 07 with thickness 02, a 0.8 mm nose radius and an integrated MM4 chipbreaker, supplied in the Tiger·tec Silver series by Walter Tools. As an indexable turning insert, it fits standard toolholders made for the DCMT form, enabling straightforward replacement and minimal set-up time. The coated-carbide construction supports repeatable cutting performance and makes the insert suitable for continuous production environments.

FAQ

Which materials is this insert suitable for?
The DCMT070208-MM4 WMP20S is intended for stainless steel (ISO group M) and is optimised for the toughness and heat sensitivity typical of these alloys.

What advantages does the Tiger·tec Silver grade provide?
The Tiger·tec Silver coating on the WMP20S grade enhances heat and wear resistance while preserving cutting-edge stability, which helps maintain tool life and surface consistency when machining stainless steels.

What information is encoded in the DCMT070208-MM4 designation?
DCMT refers to a rhombic 55° insert form; 07 denotes the insert size, 02 the thickness, 08 corresponds to the 0.8 mm nose radius and MM4 identifies the chipbreaker geometry incorporated in the insert.

How does the MM4 chipbreaker affect machining?
The MM4 chipbreaker promotes predictable chip formation and evacuation in demanding materials, reducing the likelihood of chip-related interruptions and supporting steady cutting conditions.

Can this insert be used in standard toolholders?
Yes, the insert format is compatible with standard toolholders designed for DCMT inserts, allowing simple indexation and quick replacement to minimise downtime.
