TNMG160408-FM5 WMP20S indexable turning insert — Tiger·tec Silver, for stainless steel (Walter Tools)

A TNMG160408-FM5 WMP20S indexable turning insert engineered for medium to robust machining of rostfreie Stähle, offering controlled chip formation and a durable cutting edge.

• Tiger·tec Silver coated carbide grade WMP20S
• Optimised FM5 chipbreaker for reliable chips
• Triangle 60° form with 0.8 mm corner radius
• Negative 0° relief for durable cutting edge
• Developed for stainless steel machining

Consistent machining of stainless steel with a coated grade that reduces risk

The Tiger·tec Silver series combines a modern coating system with a robust substrate to address the specific challenges of machining stainless steel. These materials are prone to work hardening and tend to form long, sticky chips; the WMP20S grade is formulated as a coated carbide to support secure chip formation and maintain a stable cutting edge under increased thermal loads. The coating reduces adhesion and improves wear behaviour, which leads to more predictable cycle times and fewer interruptions for edge dressing.

Geometry designed to balance edge strength and surface quality

A triangular 60° insert form with a 0.8 mm corner radius and negative 0° relief delivers a conservative cutting geometry that prioritises edge strength. The FM5 chipbreaker is shaped to control chip flow across a range of feeds, reducing the likelihood of built-up edge and easing chip evacuation in continuous turning operations. The combination of form and chip control supports consistent component tolerances and surface quality while extending the interval between indexings.

Productivity gains from reduced downtime and longer tool life

The coated grade and chipbreaker work together to improve process security and extend tool life, which reduces tool-change frequency and associated machine downtime. For production environments where throughput and repeatability matter, the insert’s properties translate into measurable savings: fewer unexpected stops, steadier cycle times and improved spindle utilisation. The robust edge geometry also permits reliable performance when encountering variable workpiece conditions typical for rostfreie Stähle.

Practical application notes and holder compatibility

The insert is intended for conventional indexable turning toolholders that accept TNMG profiles and is suited to turning operations from finishing to medium roughing under stable setups. For best results on rostfreie Stähle, use appropriate coolant strategies and moderate feeds to complement the FM5 chip control; reduced cutting speeds may prevent rapid thermal build-up on some alloys. For more detailed cutting data or holder recommendations, refer to technical sheets or consult with the supplier for matching toolholder solutions.
