CCMT09T304‑MM4 WMP30G – Indexable turning insert, rhombic 80°, for stainless steel machining by Walter Tools

The CCMT09T304‑MM4 WMP30G is an indexable turning insert designed for robust and consistent performance when machining stainless steel, combining a specialised chipbreaker with a Tiger‑tec Gold coated, coated‑carbide grade for improved process stability.

• Tiger‑tec Gold coated for extended tool life
• Optimised MM4 chipbreaker for stable chips
• Rhombic 80° form with 0.4 mm corner radius
• Specifically for stainless steel machining

Consistent cutting performance for stainless steel components

The Tiger‑tec Gold coating and the WMP30G grade deliver stable chip formation and reduced tendency to build up on the cutting edge when machining tough alloys. This combination supports predictable wear behaviour and longer edge life, which translates directly into fewer tool changes and less unplanned downtime. The coated‑carbide substrate is engineered to withstand the heat and adhesion tendencies typical of austenitic and other stainless steels, ensuring that the machining process remains efficient even under medium to more demanding cutting conditions.

Geometry that improves surface finish and process reliability

A rhombic 80° insert form with a 0.4 mm corner radius and a 7° clearance angle provides a balanced geometry for both finishing and light roughing passes. The compact corner radius reduces cutting forces and helps to maintain a sharp, stable edge, producing consistent surface quality and repeatable dimensional results. These geometric choices are particularly effective in turning operations where control of cutting load and thermal influences is critical for maintaining tolerances on stainless steel parts.

Chip control and productivity gains with the MM4 breaker

The MM4 chipbreaker is optimised for the material behaviour of stainless steel, promoting short, controllable chips and preventing long stringing that can interrupt automated cycles. Improved chip control reduces the need for operator intervention and enhances throughput; combined with the Tiger‑tec Gold wear characteristics, the insert supports sustained productivity and lower unit costs over long production runs. The result is a pragmatic blend of tool life and process security that benefits batch production and single‑piece flows alike.

FAQ

What materials is this insert optimised for?
This insert is optimised for machining stainless steel; the WMP30G grade and Tiger‑tec Gold coating specifically address the adhesion and heat issues common with those alloys.

Which chipbreaker is fitted and what benefit does it provide?
The MM4 chipbreaker integrated in this insert promotes short, controllable chips and improves process stability when turning stainless steel workpieces.

How does the insert geometry affect surface quality?
The rhombic 80° form with a 0.4 mm corner radius and 7° clearance reduces cutting forces and helps maintain a sharp edge, resulting in consistent surface finish and dimensional repeatability.

Is this insert suitable for both finishing and light roughing?
Yes; the combination of corner radius, clearance angle and chip control makes the insert suitable for finishing and light roughing operations on stainless steel components.
