SNMG190612-RM5 WMP20S turning insert — Tiger·tec Silver, RM5 chipbreaker, Walter Tools

SNMG190612-RM5 WMP20S is a square 90° indexable turning insert designed for medium to robust machining of stainless steel, offering a stable cutting edge and tailored chip control for production environments.

• Tiger·tec Silver coating for thermal stability
• Optimised RM5 chipbreaker for stainless steel
• Square 90° form with 1.2 mm corner radius
• Grade WMP20S for medium to robust conditions

Consistent cutting performance with thermal resistance

The Tiger·tec Silver coating delivers increased resistance to heat and abrasion, which translates directly into consistent cutting performance when machining stainless steel. The coated cemented carbide substrate paired with the WMP20S grade is engineered to reduce edge build-up and maintain a stable cutting edge under the typical heat generation of stainless steel machining. This leads to fewer interruptions for edge dressing and more predictable production cycles, supporting throughput in both single-part and batch operations.

Predictable chip control for safer processes

Equipped with the RM5 chipbreaker, the insert encourages the formation of manageable chips even under varying feed and depth conditions. Stable chip formation reduces the risk of entanglement and improves surface integrity on the workpiece, which is especially important for stainless steel that tends to be ductile and gummy. The result is enhanced process reliability and a reduced need for secondary finishing, supporting efficient downstream handling and safer operator conditions.

Geometry tuned for dimensional stability and repeatability

The square 90° plate geometry with a 1.2 mm corner radius provides a good balance between strength and edge sharpness, offering predictable radial engagement and repeatable tool offsets. The 0° negative rake contributes to a robust cutting edge and improved tool life in heavy or interrupted cuts. These geometric choices make the indexable insert suitable for turning tasks where repeatable part quality and dimensional stability are required, such as in component finishing and semi-roughing operations.

Economical lifetime and easy integration into tooling systems

The combination of coating, carbide grade and chipbreaker design yields a compelling cost-performance ratio across moderate to demanding stainless steel applications. The insert’s ISO designation and the familiar SNMG form enable straightforward integration into existing toolholders and changeover routines, reducing setup time. Maintenance cycles are simplified by the insert’s resistance to edge degradation, supporting longer intervals between index changes and helping to keep machine uptime high.
