VCMT110304-FM4 WMP20S – Turning insert, Tiger·tec Silver coating for stainless steel (Walter Tools)

The VCMT110304-FM4 WMP20S is a rhombic 35° turning insert with an FM4 chipbreaker, designed to deliver stable chip formation and reproducible performance when machining stainless steel under medium to robust conditions.

• Tiger·tec Silver coating for improved wear resistance
• WMP20S grade for stainless steel machining
• FM4 chipbreaker for stable chip control
• Rhombic 35° geometry with 7° clearance

Fewer process interruptions through stable chip control

The Tiger·tec Silver-coated grade offers a combination of wear resistance and toughness that supports predictable chip formation when cutting austenitic and other stainless steels. The FM4 chipbreaker is optimised for moderate to heavy cut depths, producing short, controllable chips that reduce the risk of entanglement and machine stops. By reducing unplanned interruptions, the tool contributes to a more continuous production flow and lower overall machining costs.

Geometry tuned for consistent surface quality and tool life

The rhombic 35° insert geometry and a clearance angle of 7° provide a compromise between strength and accessibility in shoulder and finishing operations. The 0.4 mm corner radius helps to improve edge strength while maintaining a fine surface finish on the component. These geometric choices extend tool life in applications where dimensional repeatability and surface integrity are required, such as serial production of fittings or precision components made from stainless alloys.

Coating and grade benefits translated into machining results

The WMP20S grade, a coated carbide from Walter Tools’ Tiger·tec Silver family, is formulated to handle the high heat and work-hardening tendency of stainless steel. The coating reduces flank wear and helps maintain a stable cutting edge over longer intervals. For production managers, this translates into fewer insert changes, more consistent component tolerances and a reduced need for corrective rework — measurable gains in both time and material yield.

Practical fitment and workshop handling

The insert conforms to standard tooling pockets for its designation and is supplied in the common 11 mm inscribed circle and 03 thickness format, allowing quick replacements during tool changes. The nominal designation and consistent tolerance class ensure interchangeability and predictable performance across batches. For shops aiming to standardise tooling for stainless steel turning, this insert represents a balanced choice between robustness and surface quality.

FAQ

What materials is this insert suited for?
The insert is optimised for stainless steel machining; the WMP20S grade and Tiger·tec Silver coating support secure chip formation and wear resistance in those alloys.

How does the FM4 chipbreaker affect cutting?
The FM4 chipbreaker produces compact, controllable chips in moderate to robust turning operations, improving process reliability and reducing the chance of chip-related stoppages.

Is this insert compatible with standard toolholders?
The insert follows the VCMT designation and common dimensional standards (11 mm inscribed circle, 3.00 mm thickness), enabling fitment in standard holders designed for VCMT inserts.

What performance gains can be expected from the Tiger·tec Silver coating?
The coating enhances heat resistance and reduces flank wear on the cutting edge, yielding longer edge life and more consistent component tolerances in serial stainless steel turning.
