CCMT060204-RM4 WMP20G – Indexable turning insert (Rhombic 80°, for stainless steel) by Walter Tools

CCMT060204-RM4 WMP20G is a rhombic 80° indexable insert designed for turning and boring operations on stainless steel, combining the Tiger·tec Gold grade with an RM4 chipbreaker for secure chip control and extended edge stability

• Tiger·tec Gold grade for extended life
• RM4 chipbreaker optimised for stainless steel
• Rhombic 80° geometry for versatile cutting
• 0.4 mm corner radius for precise surface finish

Consistent machining performance for stainless steel components

The combination of the WMP20G cutting grade and the RM4 chipbreaker targets the typical challenges of machining stainless steel: material toughness, built-up edge tendency and heat accumulation. By promoting stable chip formation and reduced friction, this configuration contributes to longer tool life and fewer interruptions in the production cycle. The result is a reliable process with improved repeatability and predictable productivity gains for series turning and finishing operations.

Geometry and edge design that improve production quality

The rhombic 80° insert geometry provides a good balance between approachability and strength, while the 0.4 mm corner radius supports consistent surface finish without sacrificing edge robustness. A 7° clearance angle reduces rubbing at the flank face and helps to avoid premature wear during interrupted cuts. These geometric choices are intended to enable stable cutting conditions and minimise the need for frequent insert changes, supporting efficient workshop throughput.

Coating and grade technology for robust tool life

Built on the Tiger·tec Gold coating concept, the cutting material addresses adhesion and thermal loads typical of stainless-steel machining. The coated cemented carbide composition enhances oxidation resistance and wear control under moderate to robust cutting conditions. For operations where reliable edge performance and reduced down-time are priorities, this coated grade offers a measurable improvement in process security compared with uncoated grades.

Practical advantages and workplace integration

As an indexable insert in the CCMT family, the component fits standard toolholders and allows quick index changes to restore cutting geometry without regrinding. The compact plate designation and standard thickness are suitable for a wide range of turning setups, keeping inventory management straightforward. Combined with the proven chip control of the RM4 geometry, the insert supports stable swarf handling and reduces the risk of workpiece surface defects during medium to heavy turning of stainless alloys.

FAQ

Which materials is this insert intended for?
The CCMT060204-RM4 WMP20G is specified for stainless steel machining (ISO group M), using the Tiger·tec Gold grade to manage toughness and heat-sensitive behaviour.

What does the RM4 chipbreaker provide?
The RM4 chipbreaker on this insert enhances chip control during turning of stainless steel, promoting short stable chips and reducing the risk of built-up edge.

How does the 0.4 mm corner radius affect the finish?
A 0.4 mm corner radius offers a compromise between edge strength and surface quality, supporting good finishes without unduly weakening the cutting edge.

Is this insert compatible with standard CCMT toolholders?
The CCMT060204-RM4 designation corresponds to the standard CCMT family; it is compatible with toolholders designed for CCMT-format indexable inserts.

What cutting conditions suit this coated grade?
The Tiger·tec Gold WMP20G grade is intended for medium to robust cutting conditions on stainless alloys, where stable edge performance and controlled wear are required.
