CCMT09T304-RM4 · CCMT09T304-RM20G WMP20G — Rhombic 80° turning insert for stainless steel, Tiger‑tec Gold, Walter Tools

A CCMT09T304-RM4 WMP20G is a rhombic 80° turning insert developed for medium to robust machining conditions on stainless steel, providing stable cutting performance with Tiger‑tec Gold coating.

• Tiger‑tec Gold coated carbide grade WMP20G
• Optimised for stainless steel machining
• Rhombic 80° shape, 0.4 mm corner radius

Greater throughput through coated‑grade performance

The Tiger‑tec Gold coated carbide formulation combines wear resistance with thermal stability to maintain a stable cutting edge under the challenging conditions of machining stainless steel. This results in more predictable tool life and fewer interruptions for index changes, which improves overall shop throughput. The combination of the WMP20G grade and the RM4 chipbreaker promotes secure chip control, reducing the risk of built‑up edge that typically degrades surface finish and cycle time.

Geometry that improves surface quality and process reliability

The rhombic 80° geometry paired with a 0.4 mm corner radius and a 7° clearance provides a balanced contact area for turning operations. A defined corner radius supports smoother transitions and better load distribution on the cutting edge, which translates to improved surface finish and reduced micro‑chipping. The RM4 chipbreaker shapes chips for stable evacuation, lowering the chance of entanglement and easing handling. For those unfamiliar, the corner radius is the small rounded edge at the insert tip that influences strength and finish: larger radii increase strength but may raise cutting forces, while the 0.4 mm radius here offers a pragmatic compromise for stainless steels.

Practical selection and application advice for shop environments

The insert is supplied in the CCMT09T304 format with a T3 thickness and size designation 09, making it compatible with standard turning toolholders that accept rhombic 80° indexable inserts. Its specification for the ISO M group confirms suitability for stainless steel grades that generate toughness and heat; the coating reduces adhesion and extends edge life. When integrating this insert into production, select cutting parameters that mitigate heat build‑up—moderate cutting speeds and steady feed—so the coated grade can deliver its full potential. Walter Tools’ emphasis on process reliability supports consistent results across batch and single‑piece production.

FAQ

What materials is this insert best suited for?
The CCMT09T304-RM4 WMP20G is optimised for stainless steel (ISO M), with the Tiger‑tec Gold coating and RM4 chipbreaker specifically designed to manage the toughness and heat sensitivity of these alloys.

How does the RM4 chipbreaker affect machining?
The RM4 chipbreaker on this Walter Tools insert shapes chips for reliable evacuation and reduces the likelihood of built‑up edge, improving surface finish and enabling more stable machining cycles.

Can the insert be used for finishing operations?
Yes, the combination of a 0.4 mm corner radius and controlled geometry permits good surface quality; however, finishing parameters should be selected with lower feeds and appropriate speeds for best results.

Which toolholder types accept the CCMT09T304 format?
Standard turning toolholders designed for rhombic 80° indexable inserts with CCMT format are compatible; ensure the holder supports the 09 size and T3 thickness for correct seating.

What benefit does the Tiger‑tec Gold series provide?
Tiger‑tec Gold enhances wear resistance and thermal stability, offering extended edge life and consistent cutting performance when machining demanding materials such as stainless steel.
