VCMT110302-FM4 WMP20S — turning insert (rhombic 35°, for stainless steel) by Walter Tools

VCMT110302-FM4 WMP20S is a rhombic 35° turning insert engineered for machining stainless steels under medium to robust conditions

• Tiger·tec Silver coating for superior wear resistance
• FM4 chipbreaker for controlled chips in stainless steel
• Rhombic 35° shape with 0.2 mm corner radius

Proven coating and grade for demanding stainless-steel work

The Tiger·tec Silver technology and the WMP20S grade are tuned to resist the common challenges of machining stainless steel, such as high ductility and heat-induced work hardening. The coated carbide substrate promotes wear resistance and helps maintain a stable cutting edge over longer cycles, which improves process reliability in batch production. By combining a coating designed for adhesion and thermal stability with a grade optimised for tough alloys, the insert reduces unexpected edge failure and supports consistent surface quality.

Geometry and chip control that improve productivity

The insert’s FM4 chipbreaker works together with the rhombic 35° geometry to produce predictable chip formation and evacuation during turning. The modest 0.2 mm corner radius and 7° clearance offer a balanced compromise between edge strength and cutting precision: the small radius supports fine finishes and dimensional control, while the chipbreaker reduces built-up edge and promotes effective swarf removal. For practical terms, this means fewer interruptions to clear chips and a steadier machining cycle time.

Designed for repeatable performance and lower downtime

Built as part of Walter Tools’ Tiger-tec Silver series, this insert supports repeatable tool life and consistent results across runs, which contributes directly to higher machine utilisation and lower per-part costs. In production environments where secure chip control and stable edge life are decisive, the insert’s combination of coated substrate and FM4 geometry minimises the need for frequent indexings or insert changes. Technical staff benefit from predictable wear patterns and easier process windows when specifying these inserts for stainless-steel turning tasks.

FAQ

What materials is this insert intended for?
The VCMT110302-FM4 WMP20S by Walter Tools is designed primarily for stainless steel (ISO group M) machining, offering stable chip formation and wear resistance for such alloys.

How does the FM4 chipbreaker affect machining of stainless steel?
The FM4 chipbreaker on this insert promotes short, manageable chips and reduces the risk of built-up edge when turning stainless steel, improving surface finish and process stability for the VCMT110302-FM4 WMP20S.

What is the benefit of the 0.2 mm corner radius?
A 0.2 mm corner radius gives a controlled compromise between cutting-edge strength and fine surface finish, allowing the insert to deliver repeatable dimensional accuracy and good surface quality.

Is this insert suitable for heavy roughing operations?
The VCMT110302-FM4 WMP20S is optimised for medium to robust conditions on stainless steels; the combination of grade and geometry supports productive turning, though tool choice should match the specific depth of cut and feed for heavy roughing.

Which feature contributes most to extended tool life?
The Tiger·tec Silver coating together with the WMP20S grade provides the principal contribution to extended edge life by enhancing thermal stability and wear resistance under demanding cutting conditions.
