CNMG160616-MM5 WMP20G Drehwendeschneidplatte – Tiger·tec Gold, for rostfreier Stahl (Walter Tools)

CNMG160616-MM5 WMP20G is a negative-rake rhombic insert designed for stable turning of rostfreier Stahl in medium to robust machining tasks

• Tiger·tec Gold coating for stable edge life
• Optimised MM5 chipbreaker for chip control
• Rhombic 80° insert with 1.6 mm corner radius
• Suitable for rostfreier Stahl (ISO M)

Higher productivity through coated-carbide technology and reliable chip control

The combination of the Tiger·tec Gold coating and the WMP20G grade creates a consistent cutting edge that reduces unexpected wear and supports longer tool cycles. Coated carbide technology offers thermal and abrasive resistance, which helps to avoid build-up on the cutting edge when machining rostfreier Stahl — a material group prone to toughness and heat generation. The integrated MM5 chipbreaker is optimised for secure chip formation, lowering the risk of stringing and interruptions. For production environments seeking measurable throughput gains, this insert aims to reduce changeover frequency and maintain part tolerances with predictable tool life.

Geometry tuned for dimensional accuracy and surface quality

The rhombic 80° shape with a 1.6 mm corner radius and a 0° (negative) free angle gives a balanced compromise between strength and finish capability. Negative rake geometry increases edge robustness under interrupted cuts and heavy engagement, while the moderate corner radius supports a consistent surface finish without sacrificing resistance to edge chipping. The CNMG format provides versatile seating in standard toolholders, enabling stable clamping and repeatable positioning. These geometric choices translate into reduced vibration, improved process stability and a lower rate of rework for turned components.

Operational advantages and recommended applications

Designed for ISO group M, this insert is targeted at machining rostfreier Stahl in applications with medium to robust cutting conditions where edge security and controlled chip flow are priorities. The coated carbide substrate resists thermal softening and abrasive wear, which supports consistent part quality across long runs. As part of Walter Tools’ Tiger·tec Gold family, the insert benefits from a modern coating stack that enhances process reliability and repeatability. Selection of this insert is particularly advantageous where a combination of productivity and reliable surface finish is required, such as in general engineering and component production for demanding corrosion-resistant alloys.

FAQ

Which materials are recommended for this insert?
The CNMG160616-MM5 WMP20G is specified for rostfreier Stahl (ISO M) and is optimised for the toughness and thermal behaviour typical of these alloys.

What role does the MM5 chipbreaker play?
The MM5 chipbreaker on the insert promotes controlled chip formation and reduces the chance of long, stringy chips when turning rostfreier Stahl, improving process reliability.

How does the Tiger·tec Gold coating benefit production?
Tiger·tec Gold on the WMP20G grade increases thermal and abrasive resistance of the cutting edge, which supports longer tool life and consistent part quality in serial production.

What geometry should be expected when selecting a holder?
The rhombic 80° shape with a 1.6 mm corner radius and a 0° negative rake requires holders compatible with CNMG inserts and negative-rake seating for secure clamping and repeatable positioning.

Is this insert suitable for finishing and semi-finishing?
Yes; the combination of the moderate corner radius and coated carbide construction makes the insert suitable for semi-finishing and finishing operations in conditions where a robust edge is required.
