CCMT09T308-MM4 WMP20S turning insert — Walter Tools, Tiger·tec Silver, suited for stainless steel, 7° relief

CCMT09T308-MM4 WMP20S is an indexable turning and boring insert designed for machining stainless steels with robust chip control and consistent cutting performance

• Tiger·tec Silver coating for stainless steel
• Stable chip formation under tough conditions
• Rhombic 80° geometry, 7° relief angle

Improved cutting reliability for stainless steels

The combination of the WMP20S grade and Tiger·tec Silver technology offers a coated carbide solution optimised for the challenges of machining stainless steel. The cutting material supports secure chip formation where work-hardening and built-up edge can otherwise disrupt production. With the MM4 chipbreaker the insert promotes predictable chip segmentation and evacuation, which directly reduces stoppages and the risk of surface defects. This increases overall process efficiency and contributes to lower scrap rates.

Geometry that delivers repeatable surface quality

The rhombic 80° insert geometry, in conjunction with a 7° relief angle and a 0.8 mm nose radius, provides controlled engagement and stable cutting forces. The Rhombic 80° form is particularly suited to both profile turning and light shoulder work, allowing a balance between accessibility and strength. The T3 thickness ensures sufficient support for the cutting edge, improving repeatability when clamped in standard tool holders and helping to maintain a consistent surface finish across multiple components.

Practical benefits for production workflows

Adopting this grade and geometry reduces tool change frequency and supports stable machining windows in medium to robust operating conditions. The insert’s design enables straightforward integration into existing tool assemblies and minimises adjustment time on the shop floor. Backed by the reputation of Walter Tools, this solution contributes to a predictable production routine, helping to meet batch tolerances and maintain cycle-time targets with fewer interruptions.
