CCMT09T308-FM4 WMP20G rhombic 80° indexable insert for stainless steel, Walter Tools

The CCMT09T308-FM4 WMP20G is a rhombic indexable turning and boring insert engineered for reliable machining of stainless steels under medium to robust cutting conditions.

• CCMT09T308-FM4 WMP20G insert, Tiger·tec Gold
• Optimised for stainless steel machining (ISO M)
• FM4 chipbreaker for secure chip control
• Rhombic 80° shape with 0.8 mm nose radius

Durable carbide grade that secures stable cutting in stainless steels

The combination of the WMP20G grade with the Tiger·tec Gold coating delivers a coated carbide solution optimised for the typical challenges of machining stainless steels (ISO M). The microstructure and coating chemistry are tuned to reduce built-up edge and to support stable chip formation, which translates directly into longer cutting edge life and fewer unplanned interruptions. In practice, this means more predictable batch runs and improved process reliability when turning or boring corrosion-resistant alloys, especially where toughness and heat generation would otherwise shorten tool life.

Geometry and chip control that improve surface finish and reproducibility

The insert’s rhombic 80° platform, combined with a 0.8 mm nose radius and 7° clearance, provides a balance of cutting strength and versatility for profile and finishing passes. The FM4 chipbreaker is tailored for stainless applications and ensures consistent chip segmentation and evacuation under varying cutting parameters. The insert thickness T3 and the CCMT form give mechanical stability at the cutting edge, reducing vibration and helping to achieve a repeatable surface roughness while protecting the cutting edge from thermal and mechanical overload.

Greater process security and economical series machining

Designed for medium to robust conditions, this indexable insert contributes to higher process security and measurable gains in productivity: fewer tool changes, stable cutting forces and improved component finish. The consistent edge maintenance provided by the grade and geometry supports predictable tool life, simplifying production planning and reducing scrap risk. As part of Walter Tools’ Tiger·tec Gold family, the insert is suited to environments where repeatable performance and reliable chip control are priorities, offering a practical route to lower cost per component in serial production.
