• Optimised RM4 chipbreaker for chip control
• Suitable for stainless steel machining (ISO M)
• Rhombic 55° DCMT insert, 0.4 mm corner radius

Consistent results through optimised geometry and coating

The combination of a coated carbide grade and a targeted chipbreaker design yields measurable process advantages. The WMP20G grade in the Tiger·tec Gold family is formulated for machining stainless steel, where workhardening and built-up edge are typical challenges. By pairing the RM4 chipbreaker with a rhombic 55° insert geometry and a 7° clearance, the insert promotes secure chip formation and repeatable cutting conditions. The practical result is reduced rework and fewer unscheduled tool changes, which supports continuous, efficient production.

Technical design translated into workshop benefits

The insert’s 0.4 mm corner radius and robust face geometry improve edge strength while maintaining access to tighter profiles. As an indexable turning solution, the DCMT form provides a compromise between strength and reach: the 55° diamond shape enables both robust grooving and general turning operations. The Tiger·tec Gold coating enhances wear resistance and thermal stability, assisting in maintaining a stable cutting edge under varying stainless steel conditions. For operations seeking reliability rather than experimental cutting windows, this combination reduces the likelihood of edge chipping and delivers a more consistent finish.

Practical application and process guidance for production use

In series production where process stability and surface quality matter, the insert’s design supports predictable behaviour across batches. The RM4 chipbreaker helps control chip form in interrupted cuts and during variable feed conditions commonly encountered with stainless steels. For workshop planning, using a proven indexable insert like this one simplifies inventory and tool change routines and contributes to steady productivity gains. Complementary tools and correct clamp rigidity are advised to fully exploit the insert’s strengths, and short checks after initial runs will confirm cutting parameters for sustained performance.
