TCMT110204-RM4 WMP20G – Turning and boring indexable insert, Tiger·tec Gold, for stainless steel — Walter Tools

TCMT110204-RM4 WMP20G is a coated carbide indexable insert designed for turning and boring operations in stainless steel, combining a 60° triangular form with a 0.4 mm corner radius for robust cutting performance

• Tiger·tec Gold coated carbide grade WMP20G
• Designed for stainless steel applications
• RM4 chipbreaker for controlled chips
• Triangular 60° insert with 0.4 mm radius

High-performance cutting where reliability matters

The Tiger·tec Gold grade WMP20G offers a balanced combination of wear resistance and toughness that supports secure chip formation when machining stainless steel. Coated carbide technology reduces flank wear and thermal sensitivity, which translates into fewer interruptions and more consistent component quality. The result is a measurable improvement in process stability for medium to robust cutting conditions, reducing the frequency of insert changes and improving overall shop-floor productivity.

Geometry engineered for consistent edge life

A triangular 60° insert with a 0.4 mm corner radius delivers a favourable trade-off between edge strength and cutting versatility. The 60° form provides three indexing positions for extended usable life, while the modest corner radius helps absorb cutting forces during interrupted cuts and heavy engagement. Together with the 7° clearance, the geometry minimises rubbing and supports a stable cutting edge, particularly when facing the challenges posed by tough-to-machine stainless steel.

Chip control and surface quality through dedicated chipbreaker design

The RM4 chipbreaker is configured to shape and evacuate chips reliably under varying feed rates, which reduces the risk of built-up edge on the insert and protects the workpiece surface. In practice, improved chip control helps maintain dimensional accuracy and repeatable surface finishes, decreasing secondary operations. For production environments where repeatability and process control matter, the combination of chip geometry and the coating system supports uninterrupted runs and consistent part quality.

Practical advantages for workshop integration

This indexable insert is supplied in a standard triangular form and is compatible with common turning tool holders that accept the TCMT geometry. The coated substrate and grade selection focus on predictable performance in stainless steel, which simplifies grade selection for operators and process engineers. By using a proven insert family, tool change intervals become easier to plan, tool inventories can be standardised, and machine uptime is increased — all contributing to lower overall machining costs.

When to choose this insert for production

Select this insert for turning and light boring operations where stainless steel is the predominant material and where a balance of edge robustness and wear resistance is required. The coated carbide and chipbreaker combination is particularly suitable for shops seeking improved process security and consistent surface results without frequent regrinding or complex tooling changes. For jobs requiring higher aggressiveness or different materials, consider matching the insert geometry and grade to the specific application parameters.
