VCMT160404-FM4 WMP20G — Turning insert (Rhombic 35°) for stainless steel, Walter Tools

VCMT160404-FM4 WMP20G is a rhombic 35° coated carbide indexable insert designed for productive turning of stainless steels in medium to robust operating conditions

• Tiger·tec Gold coating for wear resistance
• Optimised FM4 chipbreaker for stable chips
• Rhombic 35° form for versatile turning
• 0.4 mm nose radius, positive 7° relief

Increase throughput with consistent chip control

The rhombic 35° geometry and the FM4 chipbreaker combine to deliver stable chip formation and predictable machining behaviour when turning challenging alloys. With the Tiger·tec Gold technology and the WMP20G grade, the insert supports continuous production runs by reducing built-up edge and maintaining a reliable cutting edge under variable cutting forces. This leads to fewer interruptions for edge changes and a measurable improvement in cycle-time consistency for workshops working with stainless steel.

Improve surface quality and tool life in demanding turns

The coated carbide substrate and the optimisation of the chipbreaker mean the insert balances wear resistance and toughness. The positive 7° relief together with a 0.4 mm nose radius minimise cutting stresses while preserving surface finish, which is especially relevant for components where tolerance and finish matter. Selection of this insert reduces the risk of premature flank wear and provides a more consistent part output over the life of the tool, supporting predictable tool-change intervals and process planning.

Simple identification and reliable series performance

Marked as VCMT160404-FM4 WMP20G, this insert belongs to the Tiger·tec Gold series and is intended primarily for stainless steel machining under moderate to heavy conditions. The logical code and clearly defined chipbreaker make it straightforward to match the insert to the lathe holder and cutting parameters. For shops standardising on Walter Tools grades, the WMP20G sort offers a consistent compromise between edge stability and wear resistance, aiding reproducible results across batches.

FAQ

What materials is the VCMT160404-FM4 WMP20G best suited to machine?
The VCMT160404-FM4 WMP20G insert is designed primarily for stainless steel (material group M) and performs well under medium to robust cutting conditions typical for those alloys.

How does the FM4 chipbreaker affect machining performance?
The FM4 chipbreaker on this turning insert promotes reliable chip segmentation and evacuation, improving process stability and reducing the likelihood of built-up edge during continuous turning with the VCMT160404-FM4 WMP20G.

What benefits does the Tiger·tec Gold technology provide?
Tiger·tec Gold coating offers enhanced wear resistance and edge stability, extending effective tool life for Walter Tools inserts and supporting consistent part quality in longer production runs.

Can the code VCMT160404-FM4 be decoded to understand geometry?
Yes. The code identifies the insert form and size: VCMT indicates the rhombic insert family, 16 denotes the nominal size, 04 refers to thickness code, 04 (in the designation) corresponds with the 0.4 mm corner radius, and FM4 specifies the chipbreaker variant used on this WMP20G grade.

What are the nose radius and relief angle of this insert?
The turning insert provides a 0.4 mm corner radius and a 7° clearance angle, features that balance a fine surface finish with robust cutting edge support on the VCMT160404-FM4 WMP20G.
