CNMG120408-MS3 WMP20G turning insert — Tiger·tec Gold coating, for stainless steel — Walter Tools

CNMG120408-MS3 WMP20G is a negative-geometry turning insert designed for reliable machining of stainless steel in medium to robust conditions, combining a coated carbide grade with an MS3 chipbreaker and an 80° rhombic form for versatile lathe applications

• Tiger·tec Gold coating for edge stability
• Optimised MS3 chipbreaker for stainless steel
• Rhombic 80° geometry for versatile turning
• 0.8 mm corner radius for improved tool life

Stable chip control and longer edge life for stainless steel components

The CNMG120408-MS3 WMP20G insert uses Tiger·tec Gold coating together with the MS3 chipbreaker to promote dependable chip control when machining stainless steel, which commonly produces tough, work‑hardening chips. The coated carbide grade supports a stable cutting edge under elevated temperatures and promotes predictable wear behaviour; the practical benefit is fewer tool changes and more consistent component quality during medium to heavy turning operations.

Geometry and mechanical benefits that secure process reliability

Featuring the proven CNMG geometry in a Rhombic 80° shape and a 0.8 mm corner radius, the insert offers a balanced combination of strength and versatility. The negative 0° relief ensures a solid seat in standard toolholders and reduces the tendency for vibration in interrupted cuts. For production environments this means robust performance in facing, turning and semi‑finish passes while maintaining good component tolerances and surface condition.

Where this insert fits into a productive turning strategy

As part of the Tiger·tec Gold family, the insert is optimized for demanding stainless‑steel applications and supports reproducible results across batches. The grade's composition and chipbreaker design reduce edge build‑up and help to maintain cutting stability over longer tool lives, improving overall throughput. For process planners, this translates into fewer interruptions, stable cycle times and a more predictable maintenance schedule for toolholders and machines.

FAQ

What primary materials is this insert suitable for?
The CNMG120408-MS3 WMP20G turning insert is designed primarily for stainless steel (material group M) and offers reliable chip control and edge life under the specific demands of these alloys.

Which operations benefit most from this geometry and grade?
Operators will find the rhombic 80° form and WMP20G grade effective for medium to robust roughing and semi-finishing turning operations where stable cutting and reproducible surface quality are required.

How does the MS3 chipbreaker influence machining performance?
The MS3 chipbreaker promotes shorter, manageable chips and reduces the risk of built-up edge on the coated carbide, improving surface finish consistency and extending effective tool life during continuous production.

Is this insert compatible with standard CNMG toolholders?
Yes, the insert follows CNMG seating and clamping conventions; the negative 0° relief is intended for conventional negative toolholder systems used in turning applications.

What practical advantages does the Tiger·tec Gold coating deliver?
The Tiger·tec Gold coating enhances thermal stability and wear resistance on the cutting edge, which benefits cycle stability, reduces flank wear, and is particularly advantageous when machining heat‑resistant stainless steels.
