CCMT09T308-RM4 WMP30G – Rhombus 80° indexable insert for stainless steel, Tiger‑tec Gold (Walter Tools)

The CCMT09T308-RM4 WMP30G is a rhombic 80° indexable insert engineered for turning and boring operations in stainless steel, combining a Tiger‑tec Gold coated carbide grade with a chipbreaker optimised for secure chip formation.

• Tiger‑tec Gold coated carbide
• Optimised for stainless steel (ISO M)
• Rhombus 80° shape, 7° clearance
• 0.8 mm corner radius, chipbreaker RM4

Increased process stability through advanced coating technology

The Tiger‑tec Gold coating provides thermal and mechanical resilience that supports stable cutting-edge behaviour in demanding stainless steel applications. Coated carbide of this class reduces the tendency for built‑up edge and supports consistent surface quality over longer tool life. For production environments where downtime is critical, the coated grade WMP30G helps maintain repeatable results and improves overall process reliability without sacrificing productivity.

Geometry designed for secure engagement and reliable surface finish

A rhombic 80° insert geometry with a 7° clearance angle balances cutting edge strength and accessibility in turning and boring tasks. The 0.8 mm corner radius increases edge robustness for interrupted cuts and contributes to improved workpiece finish. Combined with the RM4 chipbreaker, the geometry promotes predictable chip control when machining stainless steels, where chip form and heat generation are primary concerns. These features make the indexable insert suitable for medium to robust cutting conditions.

Economical indexable solution for production machining

The insert’s format and indexable design reduce tool change time and inventory costs compared with solid‑tool approaches. The CCMT style plate size and T3 thickness provide a compact, yet rigid platform for repeatable mounting in standard toolholders. For engineering shops and CNC turning centres working predominantly with stainless steel, this insert supports steady productivity and lower running costs through fewer recutting incidents and consistent edge performance.

FAQ

What materials is this insert intended for?
The CCMT09T308-RM4 WMP30G insert is specified for stainless steel (ISO M), with the WMP30G grade optimised to promote secure chip formation and reduced built‑up edge in such alloys.

How does the RM4 chipbreaker influence machining performance?
The RM4 chipbreaker on this insert controls chip form and evacuation, improving safety and surface quality when machining stainless steels; the combination with the Tiger‑tec Gold coating enhances edge life.

Can this insert be used for both turning and boring?
Yes, the indexable CCMT geometry suits both turning and boring toolholders, offering versatility in production where a rhombic 80° seat is compatible.

What does the 0.8 mm corner radius mean for cutting conditions?
A 0.8 mm corner radius increases edge strength, allowing more robust cutting parameters and better resistance to edge chipping during interrupted or heavy cuts, while contributing to improved workpiece finish.

Is this a replacement part for standard toolholders?
The insert follows common CCMT dimensions and can be mounted in compatible toolholders designed for CCMT‑style inserts; verify seat and clamp compatibility before use.
