SCMT120408-FM4 WMP20G indexable turning insert – Tiger·tec Gold, square 90°, r0.8 – Walter Tools

A SCMT120408-FM4 WMP20G indexable turning insert engineered for medium to heavy turning of rostfreier Stahl with a focus on secure chip formation and repeatable results

• Tiger·tec Gold coating technology WMP20G
• Optimised for rostfreier Stahl machining
• Square 90° insert with r0.8 corner radius
• Chipbreaker FM4 for reliable chip control

Greater process reliability through advanced grade technology

The combination of Tiger·tec Gold coating and the WMP20G carbide grade delivers measurable improvements in edge life when machining rostfreier Stahl. The coating reduces flank wear and supports stable cutting-edge performance under the thermal and adhesive stresses typical of these alloys. For production environments this means fewer unexpected tool changes and a steadier component quality, which translates into higher overall machine uptime and improved cycle-time predictability.

Geometry and chip control that protect the tool and surface finish

A square 90° form with an r0.8 corner radius and dedicated FM4 chipbreaker provides controlled chip formation and reproducible cutting behaviour. The modest relief of 7° reduces rubbing while maintaining effective engagement in interrupted or heavy cuts. This geometry assists in lowering vibration and minimises the risk of built-up edge, resulting in a more consistent surface finish and reduced rework for turned parts.

Shop-floor advantages: predictable performance and efficient handling

As a purpose-designed indexable turning insert, the SCMT120408-FM4 WMP20G supports straightforward tool life management and quick index changes, helping to streamline setup routines on multiple machines. Compatibility with ISO group M applications confirms its suitability for rostfreier Stahl components, making it a pragmatic choice for manufacturers producing medical parts, food-industry components or general engineering shafts where secure chip control and repeatable results are required. The result is enhanced productivity with reliable, repeatable outcomes.
