Stable cutting performance for demanding stainless steel work

The Tiger·tec Gold WMP20G grade combines a coated carbide composition with a chipbreaker engineered for challenging materials, delivering edge stability where thermal load and material toughness are high. In practical terms, this means fewer interruptions from built-up edge and a steadier machining process when turning stainless steel. The result is more consistent dimensional accuracy and reduced risk of unexpected rework, which supports uninterrupted production schedules in contract machining and in-house turning operations.

Geometry that ensures consistent surface quality and predictable feeds

The Rhombus 55° insert form with a 0.4 mm corner radius and a 7° clearance angle provides a reliable cutting geometry that balances strength and accessibility. The modest corner radius contributes to robust edge life while permitting acceptable surface finish in finishing and light semi-finishing passes. With a T3 plate thickness and the specified clearance, the insert supports repeatable tool settings and predictable process parameters, facilitating faster set-up and more uniform part quality across batch runs.

Cost-effective tool life and controlled chip behaviour

Equipped with the MM4 chipbreaker, this insert is designed to promote controlled chip formation under the heat-prone conditions typical of stainless steel. The combination of grade and chip control reduces the frequency of insert changes and minimises machine downtime, yielding a favourable tool-life-to-cost ratio. For shops focused on throughput and process reliability, these characteristics translate into measurable operational benefits without sacrificing the precision required by tight tolerances.

Application advice and process fit

This insert is suitable for turning operations on stainless steel in medium to robust cutting regimes. The Tiger·tec Gold technology supports sustained productivity where surface integrity and edge stability are priorities. For optimal results, match the insert geometry and chipbreaker to the intended feed and depth of cut; the rhombic form offers flexibility for a range of turning tasks, from profiling to general external turning. For further machining parameters or grade comparisons, consult technical advisors to adapt speeds and feeds to specific machines and workpiece conditions.
