Increased productivity through advanced coating and chip control

The first measurable advantage comes from the combination of the Tiger·tec Gold coating and the WPP30G grade, which is a coated carbide formulation optimised for steel applications. This surface technology improves thermal stability and wear resistance during continuous cutting cycles, translating into longer tool life and fewer insert changes on the toolholder. The integrated MP5 chipbreaker is engineered to shape and evacuate chips consistently under the thermal and mechanical conditions typical for ISO P materials, reducing the risk of built-up edge and machine downtime. As a result, cycle times are often shorter and process stability is enhanced, supporting higher productivity in series production.

Robust cutting geometry for secure, repeatable machining

A core strength of this insert is its geometry: a triangular 60° form with a 0.8 mm corner radius and 0° negative rake gives a solid cutting edge with resistance to mechanical shock and interrupted cuts. The insert’s tolerance class M supports consistent seating and repeatability in indexable toolholders, which is crucial for maintaining dimensional quality across workpieces. The practical consequence is fewer part rejects and lower rework rates, especially when machining unalloyed or alloyed steel where heat and chip formation demand a stable geometry. The designation TNMG220408-MP5 identifies the nominal form and thickness, making it straightforward to match the insert to existing holder systems.

Application scope and cost-efficiency in everyday turning

Designed for ISO P (steel) applications, this grade offers a balance between wear resistance and toughness, making it suitable for a wide range of turning tasks from medium- to high-duty operations. The predictable chip formation delivered by the MP5 geometry helps to avoid chip-related stoppages and tool damage, which contributes directly to lower overall machining costs. For production environments seeking a dependable standard insert for batch or continuous turning, the combination of Tiger·tec Gold surface treatment and the WPP30G grade supports consistent surface finish and dimensional accuracy while extending the intervals between insert changes. Technical advice is available for optimising cutting data to match material variants and machine capabilities.
