CCMT120412-RM4 WMP20S — Walter Tools indexable insert, Tiger‑tec Silver, for stainless steel

The CCMT120412-RM4 WMP20S is an indexable turning and drilling insert engineered for dependable performance when machining stainless steel in medium to robust operating conditions.

• Tiger‑tec Silver coating for long tool life
• Optimised RM4 chipbreaker for stainless steel
• Rhombic 80° form with 7° relief angle
• Corner radius 1.2 mm for edge stability

Consistent cutting performance for demanding stainless applications

The combination of the Tiger‑tec Silver coating and the WMP20S grade delivers reliable wear resistance on stainless materials, counteracting common issues such as built-up edge and thermal softening. The RM4 chipbreaker promotes short, controllable chips, reducing the risk of entanglement in shafts and bores and helping to maintain consistent surface finish. For production environments that prioritise uptime, the coating’s resistance to heat and abrasion contributes directly to longer tool life and fewer indexings, supporting a measurable improvement in process efficiency.

Geometry that balances strength and versatility

The rhombic 80° plate geometry combined with a 7° relief angle gives a stable cutting orientation that reduces radial forces and improves edge engagement in interrupted cuts. A corner radius of 1.2 mm increases edge strength for tougher contact conditions while the standard CCMT size provides compatibility with common insert holders. The plate’s thickness code and format ensure a secure seat in the toolholder, which reduces vibration and promotes repeatable tool behaviour—advantages that translate into better component tolerances and longer toolholder life.

Practical advantages for production and tool management

Designed for application to ISO group M (stainless steel), this insert supports parts manufacturers, subcontractors and job shops seeking a cost‑effective route to improved productivity. The coated carbide construction simplifies process planning by offering a versatile grade for a wide range of stainless alloys. With predictable wear characteristics and stable chip control, the insert helps to reduce secondary operations and rework. Compatibility with established Walter tool systems allows straightforward integration into existing tool inventories, shortening the qualification phase and accelerating production ramp‑up.
