Reliable performance for stainless-steel machining

The coated-carbide grade from the Tiger·tec Gold series is developed to manage the particular demands of stainless steel: high toughness, a tendency to form built-up edge and elevated cutting temperatures. The combination of a dedicated coating and the WMP20G grade promotes stable chip formation and extends productive tool life in medium to heavy-duty operations. This results in fewer unplanned tool changes and more predictable cycle times on the shop floor.

Geometry that improves edge stability and surface finish

The rhombic 80° geometry and the 0.4 mm corner radius create a stable cutting edge that resists deformation and supports consistent surface quality on the workpiece. The FM4 chipbreaker is shaped to control chip flow and reduce heat concentration at the cutting zone, which helps to avoid build-up on the cutting edge and to maintain a reproducible cutting action. For turners seeking dependable finishing with repeatable results, this insert geometry balances durability and surface integrity.

Efficient machining and process predictability

The grade’s specification for ISO group M means the insert is particularly suited to rostfreier Stahl (stainless steel), where heat and adhesion are critical. The coated structure of the Tiger·tec Gold technology enhances wear resistance and edge protection, enabling higher cutting stability across a range of feeds and depths. In practice, this translates into fewer interruptions, more consistent part quality and improved overall throughput for operations that prioritise productivity and repeatable accuracy.

Practical integration into standard toolholders and setups

As a CCMT-style insert with size designation 12 and a plate thickness marked 04, the part is compatible with common clamping systems for rhombic inserts; the 80° lead angle simplifies setup for longitudinal and profiling cuts. The FM4 chipbreaker and the coated grade support machining strategies where chip control and edge life are decisive, reducing the need for constant parameter adjustments. For workshop planning, the insert complements existing Walter Tools assortments and is suitable where robust performance on stainless steel is required.
