*Rhombus 55° geometry for versatile turning
*Designed for rostfreier Stahl machining

Reliable edge life tailored to rostfreier Stahl machining

The combination of the WMP20G grade and Tiger‑tec Gold coating provides a balance of wear resistance and thermal stability that specifically addresses the challenges of rostfreier Stahl. The coated carbide composition is formulated to reduce adhesion and build‑up on the cutting edge under elevated temperatures; this leads to more consistent tool life and fewer interruptions for edge dressing. The insert’s geometry and the FM5 chipbreaker work together to promote controlled chip formation, which reduces the risk of workpiece damage and simplifies chip evacuation in continuous turning operations.

Process stability and machining performance

Rhombus 55° geometry and a 0° negative rake enable predictable engagement and favourable force distribution during turning cycles. The 0.4 mm corner radius supports robust edge strength for medium cuts while maintaining acceptable surface finish; the insert thickness provides stable clamping and repeatable positioning in standard toolholders. These measurable characteristics contribute to improved machining uptime and a lower scrap rate when processing difficult-to-cut rostfreier Stahl grades, making this insert suitable for batch production and demanding single‑piece machining alike.

Practical advantages for workshop use

Indexability and standard sizing make the insert straightforward to integrate into existing tool systems, while the FM5 chipbreaker simplifies setup by delivering consistent chip shapes across varying feeds. The insert’s specification reduces the need for frequent process adjustments, offering time savings during tool changes and setup verification. For shops seeking process reliability, the combination of coating, chip control and geometry yields tangible production benefits: reduced tool consumption, steadier cycle times and improved surface quality without complex process tuning.

FAQ

Which materials is this insert suitable for?
The DNMG150404-FM5 WMP20G insert is designed principally for rostfreier Stahl; the WMP20G grade and Tiger‑tec Gold coating support secure chip formation when machining tough, heat‑prone stainless alloys.

What benefit does the FM5 chipbreaker provide?
The FM5 chipbreaker promotes controlled, short chips and reliable evacuation, reducing the risk of entangling chips and helping to maintain a consistent surface finish with fewer interruptions.

How does the Rhombus 55° geometry affect machining?
Rhombus 55° geometry offers a versatile cutting angle that balances accessibility and edge strength, permitting a range of turning operations from finishing to medium roughing without changing the basic tool setup.

Is the insert suitable for repeatable production runs?
Yes; the combination of coated grade, chip control and stable geometry supports repeatable performance and reduced variation across production batches.
