CCGT060204-MM4 CCGT060204-MM4 WSM20S — Indexable insert for drilling and turning by Walter Tools

The CCGT060204-MM4 WSM20S is an indexable insert designed for demanding machining tasks, combining a Tiger·tec Silver grade with a robust MM4 chipbreaker for use in stainless steel and heat‑resistant superalloys.

• Tiger·tec Silver for edge stability
• MM4 chipbreaker for reliable chips
• Suited for stainless steel and superalloys

Enhanced edge performance for difficult-to-machine alloys

The combination of the Tiger·tec Silver coating and the WSM20S carbide grade offers a measurable improvement in edge resilience and thermal resistance during high‑stress operations. For stainless steel and nickel‑based materials, the coated hardmetal composition reduces tendency to build‑up edge while promoting predictable wear behaviour. This results in longer effective tool life and fewer unplanned insert changes, which supports stable production rhythms and lower overall machining cost per component. The description of the grade implies a balanced trade‑off between toughness and hardness, suitable for applications where both wear resistance and edge stability are required.

Geometry and chip control that support process security

Built on a Rhombus 80° form with a 0.4 mm corner radius and the MM4 chipbreaker, the insert is tailored to maintain controlled chip formation even in materials that tend to produce long, stringy chips. The moderate corner radius helps achieve a consistent surface finish while keeping cutting forces manageable; the chipbreaker design aids evacuation and reduces the risk of recutting. Together these features contribute to process security — fewer interruptions, better repeatability and improved component quality in serial production.

Practical benefits for workshop efficiency

Tolerance class G and a 7° relief angle contribute to predictable mounting and runout behaviour in suitable toolholders, enabling reliable indexability and repeatable results across insert changes. The plate form and standardised designation simplify procurement and tool management in a workshop environment, reducing administrative friction when replacing or restocking consumables. Where cycle times and machine utilisation matter, these incremental gains translate into measurable production advantages.

Typical applications and handling guidance

The geometry and material pairings make this insert particularly effective for finishing and semi‑finishing operations during drilling, bore enlargement and turning of stainless steel and high‑temperature alloys. When integrating the insert into existing tool systems, ensure compatible clamping modules and follow recommended cutting data for coated carbide grades. Adequate coolant strategy and correct feed/speed pairing will maximise the WSM20S performance, minimise workhardening and preserve surface integrity on demanding workpieces.
