DCMT11T308-MM4 WMP30G turning indexable insert for stainless steel — Walter Tools

DCMT11T308-MM4 WMP30G is an indexable insert designed for reliable turning of stainless steel in medium to robust machining conditions

• Tiger·tec Gold coated for prolonged tool life
• MM4 chipbreaker for stable chip control
• 7° clearance for reduced rubbing and heat
• 0.8 mm nose radius for consistent surface finish

Longer operating life through advanced coating and substrate

The Tiger·tec Gold technology combines a hard, wear-resistant coating with a tough carbide substrate to extend tool life under the demanding conditions typical of machining stainless steel. This coating reduces adhesive wear and improves thermal stability, which translates into fewer tool changes and more stable production cycles. As a consequence, users benefit from improved process reliability and lower overall machining costs without sacrificing component quality. The coated carbide construction also supports consistent edge geometry for repeatable results across batches.

Geometry that stabilises cutting and surface quality

The insert geometry — Rhombic 55° form with a 0.8 mm nose radius and 7° clearance — is optimised to balance strength and surface finish. The MM4 chipbreaker is engineered to produce short, controllable chips when cutting ductile, work-hardening stainless steels, reducing interruptions and the risk of built-up edge. For less experienced users: the nose radius influences surface finish and radial strength, while the clearance angle prevents rubbing behind the cutting edge, lowering heat generation. Together these features enable secure chip formation and a consistent machined surface in a wide range of turning tasks.

Practical production benefits and application areas

With its DCMT ISO geometry and robust design, this insert suits standard toolholders that accept DCMT-style inserts and is particularly recommended where stainless steel parts are machined under medium to heavy cutting conditions. The grade WMP30G provides a compromise between toughness and wear resistance, making it suitable for continuous operations where reproducible cutting edges and steady performance are priorities. Manufacturers can expect improved uptime and fewer tool-related process deviations. For specific setup recommendations or substrate adaptions, Metav Werkzeuge offers technical consultation to match insert choice and machining parameters to the component requirements.

FAQ

What materials is this insert best suited for?
The DCMT11T308-MM4 WMP30G insert is optimised for stainless steel, with the WMP30G grade and Tiger·tec Gold coating designed to manage the toughness and heat characteristics of these alloys.

How does the MM4 chipbreaker affect production?
The MM4 chipbreaker on the DCMT11T308-MM4 WMP30G promotes short, controllable chips when machining ductile materials, improving machine uptime and reducing manual chip handling.

What surface finish can be expected with a 0.8 mm nose radius?
A 0.8 mm nose radius on the insert typically yields a good compromise between strength and surface finish, delivering consistent results on turned stainless steel components when combined with appropriate feeds and speeds.

Is the insert compatible with standard DCMT toolholders?
The geometry follows the DCMT ISO designation, so the DCMT11T308-MM4 WMP30G fits standard toolholders designed for DCMT inserts; confirm holder specifications for clearance and clamping style before use.

How does the Tiger·tec Gold coating benefit machining stainless steel?
The Tiger·tec Gold coating enhances wear resistance and thermal stability, reducing built-up edge formation when turning stainless steel, which supports longer tool life and more consistent part quality.
