VCMT110304-FM4 WMP20G turning insert — Rhombic 35°, 0.4 mm corner radius, Walter Tools

The VCMT110304-FM4 WMP20G is a rhombic 35° turning insert in the Tiger‑tec Gold family, engineered for robust performance when machining rostfreier Stahl under medium to heavy conditions.

• Tiger‑tec Gold coated carbide grade WMP20G
• Rhombic 35° geometry for versatile turning
• 0.4 mm corner radius for stable edge performance
• Suitable for rostfreier Stahl machining (ISO M)

Precise performance for rostfreier Stahl with predictable tool life

The VCMT110304-FM4 WMP20G insert combines a Tiger‑tec Gold coating with a WMP20G substrate to address the typical challenges of rostfreier Stahl: tendency to work‑harden, sticky built‑up edge and elevated cutting temperatures. The rhombic 35° geometry delivers an adaptable entering angle that balances cutting forces and surface finish, while the FM4 chipbreaker supports controlled chip formation. This engineered combination reduces the frequency of tool changes and contributes to a more predictable machining cycle, which is valuable for batch and continuous production environments.

Reliable chip control and edge stability for improved process efficiency

The FM4 chipbreaker is designed to promote short, manageable chips when turning ductile and gummy alloys, enhancing swarf evacuation and operator safety. The 0.4 mm corner radius provides a compromise between edge strength and finish capability: it increases resistance to chipping under interrupted cuts and tough feeds while still allowing acceptable surface quality. Together, these features help to lower downtime and improve overall tool utilisation — a direct benefit for production planners seeking consistent throughput.

Application guidance and integration into the workshop

This indexable insert is sized and profiled for standard toolholders compatible with VCMT geometry; the plate size and thickness make it suitable for conventional turning operations where stability is required. The grade is specified for ISO M materials, meaning rostfreier Stahl is the primary target; under these conditions the coated hardmetal and the optimised chip control contribute to lower scrap rates and more repeatable part quality. For integration into new setups, consider toolholder rigidity and coolant strategy to exploit the coating and chipbreaker benefits fully.

FAQ

What material is this insert intended for? The VCMT110304-FM4 WMP20G insert is specified for rostfreier Stahl (ISO M) and is optimised for the typical demands of those alloys.

How does the FM4 chipbreaker benefit everyday turning operations? The FM4 chipbreaker promotes consistent, controllable chips and improved evacuation, which helps maintain stable cutting conditions when machining rostfreier Stahl with the Tiger‑tec Gold grade.

Can this insert handle interrupted cuts or tougher feeds? The 0.4 mm corner radius provides enhanced edge strength, so the insert tolerates moderate interruption and more robust feeds better than very small‑radius alternatives.

Which series and coating technology does the insert use? The insert belongs to the Tiger‑tec Gold series and carries the WMP20G coated hardmetal grade for improved wear resistance in demanding stainless applications.

Is the geometry compatible with standard VCMT toolholders? Yes, the rhombic 35° VCMT geometry is compatible with standard holders designed for VCMT‑type inserts; choose a rigid holder and appropriate coolant practice to achieve best results.
