TCMT16T304-FM4 WMP20S Triangle 60° turning insert for rostfreien Stahl | Walter Tools

TCMT16T304-FM4 WMP20S is a coated carbide turning insert engineered for reliable, medium-to-robust machining of rostfreien Stahl in turning and reaming-adjacent operations.

• Tiger·tec Silver coating for long tool life
• WMP20S grade for rostfreien Stahl machining
• FM4 chipbreaker for stable chip control
• Triangle 60° insert, 0.4 mm corner radius

Proven cutting performance for rostfreien Stahl that reduces downtime

The TCMT16T304-FM4 WMP20S insert combines a coated carbide substrate with Tiger·tec Silver technology to resist heat and edge degradation when machining rostfreien Stahl. The combination improves wear resistance and supports a stable cutting edge, which translates into longer intervals between indexings and fewer unplanned tool changes. The WMP20S grade is optimised for the toughness and built-up-edge tendency of rostfreien Stahl, enabling predictable tool life and consistent part quality—key factors for efficient batch production and reduced unit costs.

Geometry and chip control explained for reliable process results

The triangular 60° geometry provides three usable cutting corners per insert, while the 0.4 mm corner radius balances edge strength and surface finish: a larger radius increases edge robustness; a smaller radius favours finer finishes. The FM4 chipbreaker is designed to produce short, controllable chips in rostfreien Stahl, minimising the risk of entanglement and improving evacuation, especially in semi-finishing and finishing passes. The 7° relief angle reduces rubbing on the flank face and helps maintain dimensional accuracy over longer runs. For users less familiar with insert nomenclature, a chipbreaker is the engineered groove and land pattern on the insert face that shapes how material breaks and evacuates during cutting.

Stability, productivity and workshop integration for everyday use

Integrating this triangular insert into established toolholders yields immediate process benefits: enhanced edge stability, improved surface integrity of turned parts and fewer interruptions for regrinding or replacement. The Tiger·tec Silver coating and WMP20S grade combine to offer a wide material acceptance within rostfreien Stahl families, increasing flexibility across workpieces without frequent tool changes. Walter Tools’ design focus on process security supports reproducible results and makes the insert a pragmatic choice for job shops and production lines seeking measurable productivity gains. For application-specific cutting data or to confirm compatibility with a selected toolholder, Metav Werkzeuge’s advisers are available to provide technical clarification and help define cutting parameters.

FAQ

What materials is this insert suited for?
The insert is designed primarily for machining rostfreien Stahl; the WMP20S grade and Tiger·tec Silver coating are selected to handle the toughness and heat characteristics of these alloys.

How does the FM4 chipbreaker affect machining?
The FM4 chipbreaker promotes short, controlled chips when turning rostfreien Stahl, improving chip evacuation and reducing the chance of chip-related interruptions.

How many cutting edges are available on this triangle insert?
The triangular 60° form provides three indexing positions, offering three cutting corners per insert to extend service life before disposal or regrinding.

Will this insert fit standard TCMT toolholders?
The designation matches common TCMT holders; however, confirm seat geometry and clamping style with the chosen toolholder to ensure secure mounting and correct cutting geometry.

What impact does the 0.4 mm corner radius have on surface finish?
A 0.4 mm corner radius improves edge strength and vibration resistance while delivering a balance between robustness and achievable surface finish on rostfreien Stahl.
