CCMT09T308-FM4 WMP20S – Rhombic 80° indexable insert for stainless-steel turning (Walter Tools)

CCMT09T308-FM4 WMP20S is a rhombic 80° indexable insert designed for turning and boring operations on stainless steel, combining a coated carbide grade with an FM4 chipbreaker for secure chip formation.

• Tiger·tec Silver coating for longer tool life
• Optimised FM4 chipbreaker for stable chip flow
• Designed for stainless steel machining
• Rhombic 80° shape with 0.8 mm corner radius

Consistent performance for stainless-steel machining

The CCMT09T308-FM4 WMP20S combines the Tiger·tec Silver coating with the WMP20S grade to tackle the specific challenges of stainless steel: toughness, tendency to form built-up edge and high heat generation. The coated carbide substrate is engineered to support safe chip formation under medium to robust conditions, reducing the risk of premature edge breakdown. The result is a dependable cut that maintains dimensional stability and reduces unscheduled tool changes, supporting uninterrupted production cycles.

Improved chip control and surface finish

A dedicated FM4 chipbreaker paired with the rhombic 80° geometry and a 0.8 mm corner radius ensures predictable chip formation and evacuation. The moderate corner radius offers a balance between strength and finish, helping to produce consistent surface quality while prolonging insert life. The 7° clearance angle optimises engagement with the workpiece and mitigates rubbing, contributing to lower cutting forces and improved thermal behaviour during continuous turning operations.

Practical application and process guidance

This insert is primarily suited to machining stainless steel and is intended for turning and boring tasks where reliability and reproducible results are required. The T3 plate thickness and standard CCMT form make it compatible with common toolholders for indexable inserts; correct clamping and recommended cutting parameters will further enhance performance. For process optimisation—such as selecting feed rates or finishing strategies—the combination of the FM4 chipbreaker and Tiger·tec Silver technology provides a stable basis for achieving repeatable results across batch and single-part production.

FAQ

What materials is this insert suited for?
The CCMT09T308-FM4 WMP20S insert is specified for stainless steel machining and is optimised for medium to robust cutting conditions.

How does the FM4 chipbreaker benefit the process?
The FM4 chipbreaker on this Walter Tools indexable insert promotes controlled chip formation and evacuation, reducing the risk of entanglement and improving surface consistency.

Can this insert be used for both turning and boring?
Yes, the rhombic 80° geometry and T3 thickness make the insert suitable for a range of turning and boring applications where a balanced edge strength and finish are required.

What advantage does the Tiger·tec Silver series provide?
The Tiger·tec Silver coating enhances thermal resistance and wear performance on coated carbide grades, supporting longer tool life and steady cutting behaviour in demanding stainless-steel operations.

How does the 0.8 mm corner radius affect results?
A 0.8 mm radius offers increased edge stability compared with smaller radii, helping to extend insert life while maintaining an acceptable surface finish for general turning tasks.
