TCMT110204-MM4 WMP20G triangle insert for stainless steel – Walter Tools

The TCMT110204-MM4 WMP20G is a triangle turning insert engineered for medium to robust machining of stainless steel, offering a balance of edge stability and consistent chip control.

• Tiger·tec Gold coating technology
• MM4 chipbreaker for controlled chips
• Triangle 60° form for versatile turning
• 7° relief angle for secure cutting

Reliable machining of stainless steel with stable edges

The Tiger·tec Gold grade delivers a coated carbide formulation designed to manage the specific challenges of stainless steel, notably workpiece toughness and heat generation. The combination of a wear-resistant grade and a precisely defined corner radius (0.4 mm) protects the cutting edge against premature failure and reduces the risk of built-up edge. This leads to more predictable tool life and consistent surface finish, which supports process stability in batch production or demanding single-part runs. The WMP20G composition aims to maintain a secure cutting edge under medium to robust conditions, reducing unplanned downtime.

Higher productivity through optimised chip control and geometry

The MM4 chipbreaker is engineered to break and evacuate chips effectively when turning stainless steel, lowering the risk of re-cutting and improving surface integrity. Combined with the triangle 60° insert shape, this geometry allows for flexible approach angles and easy indexing, which increases usable cutting edges per insert and reduces tooling costs per component. The small corner radius (0.4 mm) supports controlled engagement in finishing passes while the 7° relief helps maintain stable cutting forces, contributing to reproducible cutting conditions and predictable cycle times.

Practical benefits in workshop integration and tool handling

Compact dimensions (inscribed circle 11 mm, thickness code 02) and standard indexability make the insert straightforward to fit into common toolholders, simplifying inventory and tool change procedures. The coated carbide grade within the Tiger·tec Gold family provides improved wear resistance and thermal stability compared with uncoated alternatives, which is particularly beneficial when machining materials prone to smearing or work hardening. These properties translate into fewer operator interventions, more consistent part quality and a more efficient machining workflow overall.

FAQ

What materials is this insert suitable for?
The TCMT110204-MM4 WMP20G by Walter Tools is specified for machining stainless steel and is optimised for medium to robust conditions in that material group.

What does the MM4 chipbreaker provide in practice?
The MM4 chipbreaker on this insert improves chip fragmentation and evacuation when turning stainless steel, which supports consistent surface quality and reduces the chance of chip-related interruptions.

How does the Tiger·tec Gold technology benefit tool life?
Tiger·tec Gold coating increases thermal stability and wear resistance, helping the Walter Tools grade WMP20G to maintain a reliable cutting edge under the elevated temperatures typical when machining stainless steel.

What is the advantage of the triangle 60° form?
The triangle 60° geometry offers multiple indexing positions and adaptability to different turning angles, which increases the number of usable edges and simplifies stocking and handling.

Is the corner radius suitable for finishing passes?
With a corner radius of 0.4 mm, the insert balances edge strength and the ability to produce fine surface finishes, making it appropriate for light to medium finishing operations.
