Reliable machining of challenging alloys with consistent edge life

The Walter Tools insert in the Tiger·tec Silver range combines a coated carbide construction with a specifically tuned chipbreaker to secure predictable cutting behaviour when machining rostfreier Stahl and heat-resistant superalloys. The coating improves thermal resistance and reduces adhesion at the cutting edge, which translates into longer tool life and fewer interruptions for tool change. For production-focused environments, this results in higher uptime and lower tool consumption per part, supporting an efficient and economical process.

Precision geometry that supports repeatable surface quality

The rhombic 80° insert geometry with a 0.4 mm nose radius delivers a balance between edge strength and surface finish. A small nose radius helps achieve tighter dimensional control on bore and counterbore operations, while the 80° shape improves access in restricted features. The FM2 chipformer is optimised for medium to heavy cutting conditions, ensuring a controlled chip flow that reduces the risk of built-up edge and protects the cutting edge. This geometry is particularly advantageous where consistent surface integrity and repeatable results are required.

Practical advantages for workshop and production planning

The insert’s specification supports common industry machining strategies: durability under elevated temperature, reliable chip control and compatibility with typical cutter bodies for drilling and turning operations. As the grade is specified for the material groups S and M according to ISO 513, it is suitable where heat-resistant superalloys and rostfreier Stahl are present. This reduces the need for multiple special grades and simplifies inventory. The result is straightforward tool selection, fewer changeovers and a more predictable machining cycle time.

How the coated grade helps in day-to-day operations

Tiger·tec Silver coating technology increases resistance to thermal softening and edge wear; this means fewer interventions and a lower risk of unexpected rejects. The FM2 chipbreaker supports safer chip evacuation, which is particularly useful in deep-hole and shoulder operations where chip control is critical. These features combine to enhance process stability and contribute to measurable productivity gains in serial production.

FAQ

What materials are suitable for this insert?
The CCGT120404-FM2 WSM20S insert is designed primarily for rostfreier Stahl and heat-resistant superalloys (material groups M and S), offering thermal resilience and chip control for those alloys.

How does the Tiger·tec Silver coating influence tool life?
The Tiger·tec Silver coating improves thermal stability and reduces adhesion at the cutting edge, which increases edge life and helps maintain consistent performance under elevated temperatures.

Which chipbreaker should be expected on this insert and what is its function?
This insert features the FM2 chipbreaker, which is engineered to produce controlled chips and reduce the risk of built-up edge, aiding in safer chip evacuation during deeper or interrupted cuts.

Is the insert suitable for both drilling and turning applications?
Yes, the insert form and designation match applications for both drilling/reaming operations and certain turning or boring tasks when mounted in the appropriate tool holders designed for rhombic 80° inserts.

How does the 0.4 mm nose radius affect surface finish and edge strength?
A 0.4 mm nose radius provides a compromise between improved surface finish and sufficient edge strength, enabling accurate dimensional control while keeping the cutting edge robust under varying cutting forces.
