VNMG160404-NFT WSM20S indexable turning insert — Rhombic 35°, 0.4 mm corner radius, Walter Tools

The VNMG160404-NFT WSM20S is an indexable turning insert designed for heavy-duty machining of rostfreier Stahl and heat-resistant superalloys, offering a negative rake geometry for secure cutting-edge stability.

• Tiger·tec Silver coated grade WSM20S
• Designed for rostfreier Stahl and superalloys
• Rhombic 35° VNMG insert, 0.4 mm corner radius

Boost throughput on difficult-to-cut materials

The coated WSM20S carbide grade, part of the Tiger·tec Silver family, is formulated for machining rostfreier Stahl and high-temperature alloys. The combination of a wear-resistant coating and a tough carbide substrate promotes stable chip formation and extends tool life, which reduces unplanned tool changes and keeps machining cycles predictable. For production environments this means fewer interruptions and a measurable improvement in overall equipment effectiveness (OEE), as the insert tolerates the heat and adhesion tendencies typical of these materials.

Secure cutting edge and consistent surface quality

Featuring a 0° (negative) rake and a defined NFT chipbreaker, the geometry supports a protected cutting edge and controlled chip flow. The 0.4 mm corner radius helps maintain edge strength during interrupted cuts, lowering the risk of chipping while still delivering consistent surface finish. Translating geometry into benefit: stronger edges equal longer life and steadier dimensional results, making the insert suitable for both roughing and semi-finishing operations where repeatability is essential.

Flexible integration into established tooling systems

The VNMG160404-NFT format (16 mm) conforms to common toolholder interfaces, allowing straightforward insertion into existing turret and holder systems. The rhombic 35° shape provides a versatile approach angle for diverse turning tasks, enabling better access in shoulder and profile work. With a recognised ISO designation and stable tolerance class M, this insert supports predictable tool assembly and simplifies inventory management for workshops aiming to standardise tooling across machines.

FAQ

What materials is this insert best suited for?
The VNMG160404-NFT WSM20S insert is optimised for machining rostfreier Stahl and heat-resistant superalloys (ISO groups M and S) thanks to its Tiger·tec Silver coating and robust carbide core.

How does the 0° negative rake affect performance?
A 0° negative rake increases cutting-edge strength and resistance to mechanical and thermal shock; the VNMG geometry supports tougher cutting conditions and improves edge life in interrupted or heavily loaded cuts.

Can this insert deliver acceptable surface finishes?
Yes. While primarily aimed at productive machining, the combination of the 0.4 mm corner radius and the NFT chipbreaker helps achieve consistent surface quality in semi-finishing and finishing passes when cutting parameters are optimised.

Is this insert compatible with standard VNMG toolholders?
The VNMG160404-NFT format corresponds to widely used toolholder interfaces, enabling straightforward replacement and integration into existing turning setups.
