CCMT120404-RM4 WMP30G – Walter Tools turning and boring indexable insert with Tiger‑tec Gold coating for stainless steels

A CCMT120404-RM4 WMP30G is a rhombic 80° indexable insert designed for turning and boring where reliable chip formation and edge stability under medium to robust conditions are required.

• Tiger‑tec Gold coating for long tool life
• WMP30G grade tuned for stainless steels
• RM4 chipbreaker for reliable chip control
• Rhombic 80° form, 0.4 mm corner radius

Consistent performance through advanced coating and grade

The insert is built on the WMP30G grade and benefits from Tiger‑tec Gold coating technology, which together reduce flank wear and maintain a stable cutting edge in demanding stainless steel operations. The coated cemented carbide composition improves heat resistance and abrasion control, resulting in long tool life and fewer indexings per component. For production environments where repeatability matters, this combination delivers measurable improvements to process stability and reduces unscheduled downtime.

Precise chip control and geometry for better surface quality

With the RM4 chipbreaker and a rhombic 80° form, the geometry is designed to manage chips effectively in materials that tend to form long, stringy swarf. The insert’s 0.4 mm corner radius and nominal 4.00 mm thickness support robust edge strength while enabling a fine surface finish at typical turning feeds. The 7° clearance angle reduces rubbing and heat build-up, which helps to avoid built-up edge formation on stainless steels; operators gain improved part consistency and shorter secondary finishing times as a result.

Application focus and operational advantages

This insert is suited to turning and light boring operations where stainless steel presents challenges such as toughness and thermal sensitivity. The design supports medium to heavier cuts with secure chip breaking and predictable tool wear, allowing straightforward process planning and tool life estimation. The combination of geometry and grade also supports safer machining windows on difficult-to-machine grades, contributing to higher first-pass yield and lower in-process scrap rates. Walter Tools’ engineering focus ensures the insert aligns with standard toolholders and established tool-setting procedures.
