TCMT16T308-RM4 WMP20G triangular indexable insert – Walter Tools, Tiger·tec Gold, for stainless steel machining

TCMT16T308-RM4 WMP20G is an indexable insert designed for turning, boring and reaming applications in stainless steels, featuring a Tiger·tec Gold grade and an RM4 chipbreaker for controlled chip formation

• Tiger·tec Gold coated carbide grade WMP20G
• Suitable for stainless steel (ISO M) applications
• Triangular 60° insert with 0.8 mm corner radius
• RM4 chipbreaker for consistent chip control

Reliable performance for stainless-steel production

The Tiger·tec Gold coating and WMP20G grade combine to offer standout wear resistance under the high heat and adhesion tendencies of stainless steel. The coating technology reduces flank and crater wear, which prolongs tool life and lowers tool-change frequency, thereby improving throughput. As a coated carbide insert with a robust substrate, it is engineered for medium to heavy-duty conditions where secure edge retention and repeatable results are required. This leads to measurable productivity gains and reduced process variability in series production runs.

Improved process security through chip control and geometry

Chip management is central when machining austenitic and other tough stainless grades; the RM4 chipbreaker promotes secure chip formation and evacuation, reducing the risk of built-up edge and surface damage. The triangular 60° geometry paired with a 0.8 mm corner radius provides strength at the cutting edge and allows reliable turning operations while maintaining acceptable surface finish. The 7° clearance angle supports stable cutting forces and minimises rubbing, which helps achieve consistent component tolerances and reduces rework rates in downstream operations.

Practical integration and supplier support for production environments

The insert’s designation, TCMT16T308-RM4 WMP20G, reflects a common industrial interface for toolholders, simplifying tool assembly and inventory management. The insert thickness (T3) and 16 mm size match established toolholder standards, facilitating fast retrofit into existing tool packs. For technical queries or material-specific recommendations, Metav Werkzeuge provides application support and can advise on optimal cutting parameters for specific stainless-steel grades. Reliable supply and clear specifications aid planning for stable production cycles and predictable maintenance intervals.

FAQ

What materials is this insert suitable for?
This insert is specified for stainless steel work (ISO group M); the WMP20G grade and Tiger·tec Gold coating are optimised for the adhesion and heat characteristics of these alloys.

How does the RM4 chipbreaker affect machining?
The RM4 chipbreaker promotes controlled chip formation and evacuation, improving process security and reducing the likelihood of built-up edge when machining stainless steels with the TCMT16T308-RM4 WMP20G insert.

Can this insert be used in existing toolholders?
Yes. The TCMT16T308 geometry is a standard indexable insert format and is compatible with matching toolholders designed for triangular 60° inserts with the corresponding size and thickness.

What advantages does Tiger·tec Gold provide compared with uncoated grades?
Tiger·tec Gold coating enhances wear resistance and thermal stability. For the WMP20G grade, this translates into longer cutting life and more consistent surface quality under the demands of stainless-steel turning.

Where can machining parameters and recommendations be obtained?
Metav Werkzeuge supplies application guidance and cutting-parameter recommendations for the TCMT16T308-RM4 WMP20G insert and can provide trial values tailored to specific stainless-steel alloys.
