TCMT16T308-FM4 WMP20G triangular 60° indexable insert — Tiger·tec Gold grade for rostfreier Stahl (Walter Tools)

The TCMT16T308-FM4 WMP20G is a triangular turning and drilling indexable insert engineered for medium to robust machining of rostfreier Stahl, combining a coated carbide substrate with a dedicated chipbreaker for stable cutting performance.

• Tiger·tec Gold coated grade WMP20G
• Designed for rostfreier Stahl machining
• Triangular 60° insert, 0.8 mm corner radius
• 7° relief angle with FM4 chipbreaker

Increased cutting reliability for rostfreier Stahl applications

The combination of the WMP20G grade and the Tiger·tec Gold series delivers improved resistance to work-hardening and thermal loading common in rostfreier Stahl. The coated carbide structure supports stable chip formation and maintains a reliable cutting edge under demanding conditions. The integrated FM4 chipbreaker promotes predictable chip control, which reduces the risk of built-up edge and protects both the tool and the workpiece surface. For production environments where repeatability matters, this insert helps to keep cycle times steady and tool-change frequency low.

Geometry that balances edge strength and surface quality

A triangular 60° form with a 0.8 mm corner radius offers a compromise between robustness and finish: the radius increases edge strength for interrupted cuts and heavier feeds, while the insert geometry still allows fine surface quality when used with appropriate feeds and speeds. The 7° relief angle supports lower cutting forces on the flank and contributes to a consistent machining allowance. These geometric features make the insert suitable for both axial turning and light boring operations where a reliable edge and consistent dimensional control are required.

Productivity and integration in demanding toolpaths

Built as a coated carbide insert from the Tiger·tec Gold family, this grade is optimised for long tool life and stable machining in rostfreier Stahl. The FM4 chipbreaker is tuned for medium-to-robust cutting conditions, helping to avoid chip entanglement and improving process security on automated lathes and multi-task machines. Integration into standard toolholders is straightforward using the ISO designation; the insert supports process standardisation, enabling predictable tool management and easier batch planning. For teams aiming to improve throughput while keeping surface quality and repeatability high, this insert is a pragmatic choice.

FAQ

Which materials is this insert best suited for?
The TCMT16T308-FM4 WMP20G insert is specifically designed for rostfreier Stahl and performs best in medium to robust stainless-steel machining conditions thanks to the Tiger·tec Gold grade.

What advantage does the FM4 chipbreaker provide?
FM4 promotes controlled chip formation and efficient chip evacuation; when combined with the Tiger·tec Gold coating on the TCMT16T308-FM4, it reduces the likelihood of built-up edge and improves process stability.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm radius increases edge robustness and reduces chipping risk during interrupted cuts, while still permitting acceptable surface finishes at appropriate feeds and speeds with the TCMT16T308-FM4 geometry.

Is this insert suitable for both turning and boring operations?
Yes, the TCMT16T308-FM4 WMP20G is an indexable insert intended for turning and certain boring/upboring tasks where the triangular form and grade match the cutting conditions.

What benefits does the Tiger·tec Gold series add?
Tiger·tec Gold coating enhances wear resistance, thermal stability and edge retention, extending tool life and supporting consistent machining results in rostfreier Stahl applications.
