TCMT16T304-FM4 WMP20G indexable insert by Walter Tools — Tiger·tec Gold coated, optimised for stainless steel

The TCMT16T304-FM20G is a triangular 60° indexable insert for medium to robust machining of stainless steel, combining a Tiger·tec Gold coating with a dedicated FM4 chipbreaker for stable cutting performance.

• Tiger·tec Gold coating for long tool life
• Grade WMP20G optimised for stainless steel
• Triangular 60° insert, 0.4 mm corner radius
• 7° clearance angle, stable chip control

Reliable grade and coating for demanding stainless steel applications

The insert uses a Tiger·tec Gold coating on a coated carbide substrate, which supports secure chip formation and reduces the tendency for built-up edge that commonly affects austenitic and other stainless steels. This combination leads to improved cutting-edge life under the medium to robust cutting conditions for which this grade is specified. The material match and coating chemistry aim to maintain cutting performance where heat generation and material adhesion are greater than with general-purpose steels.

Geometry engineered for edge stability and surface quality

The triangular 60° insert geometry with a 0.4 mm corner radius and 7° clearance provides a stable cutting edge and predictable engagement, while the FM4 chipbreaker promotes controlled chip flow in interrupted or continuous cuts. The nominal plate size and T3 thickness offer mechanical rigidity for consistent results, helping to achieve repeatable surface finish and dimensional stability in serial production. Precise geometry reduces the need for frequent edge changes, supporting productive turning cycles.

Ready integration into TCMT tool systems for efficient shopfloor use

Designed in the TCMT16T304 format, this indexable tip integrates into corresponding toolholders for straightforward insertion and indexing, enabling fast tool changes and minimal setup time. The WMP20G grade from Walter Tools is intended for reliable performance across a broad stainless steel spectrum, delivering process stability and predictable wear patterns. For workshops seeking to standardise on robust inserts for rostfreier Stahl, this solution supports reduced downtime and simplified tooling logistics.

FAQ

Is this insert suitable for machining stainless steel?
Yes. The TCMT16T304-FM4 WMP20G is specifically optimised for stainless steel applications and the WMP20G grade supports secure chip formation in such materials.

What chip control can be expected with this geometry?
The FM4 chipbreaker combined with the triangular 60° geometry provides controlled chip flow and reduced risk of chip entanglement under medium to robust cutting conditions.

Which series and coating does this insert belong to?
The insert is part of the Tiger·tec Gold series; the coating provides enhanced wear resistance and process reliability for demanding stainless steel turning.

How does the corner radius affect the application?
A 0.4 mm corner radius offers a compromise between edge strength and surface finish, improving edge stability for heavier cuts while still enabling acceptable surface quality.
