CNMG120404-NMS WSM01 — Turning indexable insert (coated carbide) by Walter Tools

The CNMG120404‑NMS WSM01 is a negative‑rake turning insert designed for machining stainless steels and heat‑resistant superalloys, combining a robust geometry with a Tiger‑tec Silver coated carbide grade for demanding production conditions

• Tiger‑tec Silver coated carbide
• Optimised for stainless and superalloys
• Rhombus 80° CNMG shape with 0.4 mm radius
• Negative 0° rake for robust cutting

Reliable cutting performance for tough materials

The combination of a coated carbide grade and an optimised chip former delivers reliable machining in demanding alloys. The WSM01 grade, part of the Tiger‑tec Silver series, is formulated to maintain a stable cutting edge under elevated temperatures and adhesion‑prone conditions typical of stainless steels and superalloys. This results in fewer unexpected tool changes, reduced scrap rates and a more predictable production flow. Where thermal load and material ductility threaten edge life, the coating and substrate chemistry support continuous operation and repeatable results.

Geometry engineered for secure chip control and surface quality

The CNMG rhombic 80° shape offers versatile turning performance, while the 0.4 mm corner radius balances edge strength with surface finish. The negative 0° rake angle provides a robust cutting geometry that resists chipping and handles variable cutting conditions. The NMS chipbreaker promotes controlled chip formation, reducing the risk of built‑up edge and improving evacuation. For operations where consistent part quality and machine uptime are priorities, this geometry reduces instability and helps maintain dimensional integrity across batches.

Process efficiency and predictable tool life

A focus on process stability produces tangible economic benefits: longer intervals between insert changes, fewer machine stops and predictable performance from batch to batch. The coated grade supports higher cutting temperatures and abrasive contact, which often translates into improved tool life compared with uncoated grades in the same application class. For production environments aiming to optimise throughput and minimise variances, the insert’s construction and chip control contribute directly to efficiency and lower overall machining costs.

Practical application advice and compatibility

The insert is designated for ISO groups M and S, indicating suitability for stainless steels and heat‑resistant superalloys/titanium. Its CNMG form fits standard toolholders for rhombic 80° turning inserts; matching the insert to a holder with secure clamping and correct seat geometry ensures the expected stability. Where interrupting cuts or heavy chip loads occur, the robust grade and negative geometry help absorb shocks and maintain edge integrity. For material‑specific cutting data and feed/speed suggestions, technical consultation is recommended to align process parameters with component and machine characteristics.
