DCMT11T308-RM4 WMP20G indexable turning insert by Walter Tools — 7° clearance, 0.8 mm nose radius

DCMT11T308-RM4 WMP20G is an indexable turning insert designed for reliable machining of stainless steels in medium to robust conditions

• DCMT11T308-RM4 geometry for stable cutting
• Tiger·tec Gold WMP20G coating for stainless steel
• RM4 chipbreaker for secure chip control
• 7° clearance and 0.8 mm nose radius

Consistent chip control for continuous production

The combination of the RM4 chipbreaker and the Tiger·tec Gold WMP20G coating provides stable chip formation when machining stainless steels, reducing the risk of built-up edge and erratic evacuations. This leads to fewer interruptions, less manual chip handling and a more predictable machining cycle. The RM4 geometry is optimised to break chips reliably under varying cutting depths and feeds, which contributes directly to higher machine uptime and improved process stability in production environments.

Coating and grade deliver durable cutting performance

The WMP20G grade is a coated carbide specifically tuned for the challenges of machining stainless steel: toughness, work hardening and heat generation. The Tiger·tec Gold technology enhances wear resistance and maintains a sharp cutting edge for longer periods, so the insert sustains dimensional accuracy over multiple parts. This means fewer tool changes and more parts per tool life, translating into reduced tooling costs and higher throughput for batch and continuous turning operations.

Geometry that balances strength and surface quality

With a 0.8 mm nose radius and 7° clearance, the insert offers a compromise between robust cutting edge strength and good surface finish. The Rhombus 55° form provides positive plunge and ease of approach on various toolholders, while the specified thickness (T3) contributes to a stable seat in the pocket. Together these attributes enable steady contact conditions at the cutting edge, which helps to achieve consistent component geometry and surface integrity, particularly important when tight tolerances are required.

Practical application advice for workshop integration

The insert is suited to medium and robust turning tasks on stainless steels (ISO group M). For best results, pair the insert with appropriate coolant strategies and moderate cutting speeds to avoid excessive thermal loading; the coated grade tolerates heat but steady thermal control improves lifetime. Toolholders compatible with DCMT indexing and a secure clamping system will preserve the insert’s seating and maintain repeatability across tool changes. For shops looking to increase productivity, the grade and chipbreaker support longer uninterrupted runs and lower scrap rates.
