VBMT110304-MM4 WMP20S indexable turning insert — Tiger‑tec Silver, 0.4 mm nose radius — Walter Tools

The VBMT110304‑MM4 WMP20S is an indexable turning insert engineered for medium to robust machining of rostfreier Stahl, combining a rhombic 35° geometry with a Tiger‑tec Silver coated carbide grade for consistent performance

• Tiger‑tec Silver coated carbide
• Optimised for rostfreier Stahl
• Rhombic 35° geometry
• 0.4 mm corner radius, 5° relief

Improved process stability through advanced coating and chip control

The coated carbide grade from the Tiger‑tec Silver series provides enhanced edge stability and predictable wear behaviour under the demanding thermal and mechanical loads typical of rostfreier Stahl machining. The integrated MM4 chipbreaker promotes secure chip formation, reducing the risk of built-up edge and improving cycle reliability. For workshops seeking lower rework rates and fewer tool changes, this translates into measurable productivity gains and steadier component quality.

Geometry tailored for accessibility and surface quality

The rhombic 35° geometry combined with a 0.4 mm nose radius and a 5° relief angle enables precise contact conditions at the cutting edge. This geometry supports fine finishing passes while remaining robust enough for slightly heavier cuts, helping to reduce vibration and to improve surface integrity. The subtle nose radius balances form accuracy and tool strength, so finishing quality is improved without sacrificing reliable tool life.

Application guidance for consistent shop-floor performance

Designed for machining rostfreier Stahl under medium to robust conditions, the insert is suitable where secure chip evacuation and stable cutting edges are priorities. The coated grade is intended to handle the tendency of these alloys to produce stringy chips and to generate heat at the cutting zone; the outcome is fewer interruptions and more predictable tool change intervals. For integration into existing turning toolholders, the indexable format simplifies replacement and reduces machine downtime.

FAQ

Which materials is this insert designed for?
The VBMT110304‑MM4 WMP20S insert from Walter Tools is designed primarily for rostfreier Stahl and is optimised to handle the toughness and thermal sensitivity of these alloys.

What benefits does the Tiger‑tec Silver coating provide?
The Tiger‑tec Silver coating on this Walter Tools indexable insert improves wear resistance and edge stability, helping to maintain cutting performance and reduce unscheduled tool changes during rostfreier Stahl machining.

When should the MM4 chipbreaker be chosen over other chipbreakers?
The MM4 chipbreaker on the VBMT110304‑MM4 WMP20S is suited to conditions where controlled chip segmentation is required for rostfreier Stahl; it offers a balance between chip evacuation and surface finish for medium to robust cutting parameters.

How does the rhombic 35° shape influence accessibility and finish?
A rhombic 35° insert form provides versatile approach angles, allowing better access in tight geometries while supporting good surface quality—this is beneficial when using the VBMT110304‑MM4 WMP20S in complex turning operations.

Is the insert compatible with standard turning toolholders?
Yes, the indexable format of the VBMT110304‑MM4 WMP20S is compatible with common clamping systems for turning inserts; correct seating and torque are essential to preserve the expected performance and tool life.
