TCGT110204-MM4 WSM20S indexable turning insert, Tiger·tec Silver, for stainless steels and superalloys — Walter Tools

A TCGT110204-MM4 WSM20S indexable turning insert engineered for robust performance in the machining of stainless steels (M) and heat-resistant superalloys (S) in heavy-duty turning operations

• Tiger·tec Silver coating for heat resistance
• MM4 chipbreaker for stable chip control
• Triangle 60° insert with 0.4 mm nose radius
• 7° relief angle for secure cutting edge

Improved process reliability and extended tool life

The Tiger·tec Silver coating is a high-performance, multilayer system designed to withstand thermal and mechanical loads typical of machining stainless steels and nickel-based alloys. Combined with a dedicated substrate, this technology reduces flank wear and supports a stable cutting edge, which translates into longer tool life and fewer insert changes. For production environments where uptime and repeatable component quality matter, the coated grade offers a predictable balance between wear resistance and toughness, helping to keep cycle times consistent and rework rates low.

Consistent chip formation and secure cutting performance

The MM4 chipbreaker geometry is tuned to promote controlled chip segmentation under the challenging conditions posed by tough, ductile materials. By guiding chip flow away from the workpiece and toolholder, the insert lowers the risk of built-up edge formation and machine interruptions. The combination of chip control and a 0.4 mm nose radius delivers good surface integrity while permitting reliable turning operations, even when intermittent cuts or varying depths of cut occur. This results in fewer process deviations and improved surface finish on difficult-to-machine alloys.

Geometry and handling that support productivity

The triangular 60° shape offers three effective cutting edges per index, helping to reduce tooling costs per part. A 7° relief angle provides positive engagement with the workpiece while protecting the cutting edge from excessive radial loading. The insert thickness and format suit common clamping systems, enabling quick indexing and straightforward tool management on standard toolholders. For shops focused on repeatable setup and efficient changeover, the geometry supports fast replacement and consistent datum positions across batches.

FAQ

What materials is this insert intended for?
The TCGT110204-MM4 WSM20S insert is specified for stainless steels (M) and heat-resistant superalloys (S), utilising the Tiger·tec Silver grade for thermal and wear resistance.

How does the MM4 chipbreaker benefit production runs?
The MM4 chipbreaker on this Walter Tools grade promotes stable chip formation and evacuation, reducing interruptions and contributing to consistent surface quality across batches.

Can the triangular shape reduce tooling costs?
Yes, the triangle 60° geometry provides three indexable cutting edges per insert, offering economical edge utilisation and straightforward indexing during series production.

Is the 0.4 mm nose radius suitable for finishing operations?
A 0.4 mm nose radius balances strength and finish capability; on the TCGT110204-MM4 WSM20S it supports acceptable surface integrity while maintaining edge robustness for demanding cuts.

What cutting-edge protection does the Tiger·tec Silver coating provide?
Tiger·tec Silver enhances resistance to thermal degradation and flank wear, helping the insert maintain a sharp, stable cutting edge when machining heat-generating, tough materials.
