CCMT060208-MM4 WMP20G — Rhombic 80° indexable insert, Tiger·tec Gold, Walter Tools

The CCMT060208-MM4 WMP20G is a coated carbide indexable insert for drilling, boring and turning operations, optimised for medium to robust stainless steel machining in ISO M applications

• Tiger·tec Gold coating for wear resistance
• Designed for stainless steel (ISO M)
• Rhombic 80° geometry for stable engagement
• 0.8 mm corner radius and 7° relief angle

High-performance grade for demanding stainless steel tasks

The WMP20G grade, part of the Tiger·tec Gold family, combines a multilevel coating system with a robust substrate to reduce built-up edge and improve flank wear behaviour when cutting stainless steel. This results in more consistent tool life and fewer interruptions for tool changes, increasing process throughput. The chip control strategy embedded in the MM4 chipbreaker supports secure evacuation under the high ductility and heat-prone conditions typical for ISO M materials, translating into predictable cycle times and reduced rejects.

Geometry that stabilises machining and improves surface finish

The rhombic 80° shape provides a favourable lead angle for heavy engagement while maintaining a positive cutting action; this balances cutting forces and helps to avoid vibration on standard toolholders. A 0.8 mm corner radius increases edge strength for interrupted cuts or roughing passes, while the 7° relief angle minimises rubbing and thermal load at the flank. Together these geometric features deliver better surface integrity and repeatable dimensional results, especially when turning or boring shafts and sleeves in rostfreier Stahl.

Coating and chip management for reliable production

The coated carbide construction, identified by the Tiger·tec Gold marking, enhances thermal stability and resistance to abrasive wear, supporting longer uninterrupted production runs. The dedicated MM4 chipbreaker is tuned for stringy chips often encountered with stainless steels, promoting short, controllable chips and reduced risk of surface damage. As a Walter Tools grade, the insert benefits from proven manufacturing quality and consistent tolerances, making it suitable for both prototype work and serial production where process security matters.

FAQ

Which materials is this insert intended for?
The CCMT060208-MM4 WMP20G insert from Walter Tools is specified for stainless steel (ISO M) applications and is designed to handle the toughness and heat tendency of these alloys.

Is the MM4 chipbreaker suitable for roughing and finishing?
The MM4 chipbreaker on this Walter Tools grade is optimised for secure chip control in medium to robust cutting conditions; it performs well in both heavier roughing passes and controlled finishing where chip form and surface integrity are priorities.

Can the insert be used in standard CCMT toolholders?
Yes — the CCMT060208-MM4 designation corresponds to a common rhombic 80° insert form compatible with standard CCMT toolholders; ensure correct clamping and seat cleanliness for best repeatability.

How does the Tiger·tec Gold coating affect process stability?
The Tiger·tec Gold multi-layer coating provides improved thermal resistance and wear protection, which helps maintain a stable cutting edge and consistent tool life in rostfreier Stahl machining.
