Order the CNHU0805PPN-D57T insert via Metav Werkzeuge or ask our consultants for tailored application advice. CNHU0805PPN-D57T WSP45G milling insert — Walter Tools, Tiger·tec Gold, Rhombus 80° The CNHU0805PPN-D57T WSP45G is a coated carbide milling insert designed for versatile milling of steel, rostfreier Stahl and heat-resistant alloys, combining a robust chipbreaker with a 0° negative rake for secure cutting in demanding operations Tiger·tec Gold PVD coating for edge stability Rhombus 80° geometry for versatile milling Suitable for steel, rostfreier Stahl and superalloys Chipbreaker D57T for consistent chip control High productivity through advanced coating and grade The Tiger·tec Gold system and the WSP45G grade deliver a balanced mix of toughness and wear resistance, making the insert particularly effective where consistent tool life matters. The coated carbide substrate provides improved thermal and mechanical resistance compared with uncoated grades; in practice this means fewer interruptions for tool changes and more predictable production cycles. For many machining tasks on steel, rostfreier Stahl and heat-resistant alloys, this combination reduces the risk of premature chipping and supports stable cutting forces, which in turn helps to maintain surface quality over longer runs. Geometry that stabilises cutting and controls chips The rhombic 80° form and the specified negative rake of 0° work together to keep the cutting edge engaged with the workpiece under varying loads. The built-in chipbreaker D57T is tuned to break and evacuate chips reliably across a range of feeds, reducing the chance of re-cutting and built-up edge. For finishing cuts the geometry supports a consistent surface finish; for more aggressive operations the stable rake angle protects the edge and promotes repeatable tool behaviour. These geometric features are especially helpful when alternating between different stainless and high-temperature alloy components within the same production batch. Practical application guidance and process reliability This insert is intended for productive milling tasks where a single grade must cover several material groups. The designation P / M / S indicates suitability for unalloyed and alloyed steel, rostfreier Stahl and heat-resistant superalloys or titanium — a practical choice for mixed-production environments. When pairing with suitable cutters and feeds, the insert reduces setup complexity and supports process standardisation. For customers seeking optimisation, matching the insert to cutter geometry and cutting parameters will unlock the best compromise between cycle time and tool life; Metav Werkzeuge can advise on recommended parameters and compatible toolholders.

Predictable chip control for safer machining A carefully configured RK5 chipbreaker and the negative 0° rake geometry provide stable chip formation and evacuation during turning. The chipbreaker reduces the tendency for long, stringy chips typical of some cast-iron cuts, improving surface quality and lowering the risk of tool or workpiece damage. The Rhombic 80° insert form also supports versatile cutting angles in standard CNMA toolholders, allowing secure seating and predictable cutting behaviour across a range of turning applications. Repeatable dimensional accuracy and edge security With a 0.4 mm corner radius and M tolerance class, the insert supports consistent edge strength and repeatable results in production environments. The robust corner radius helps to absorb cutting forces during heavier engagement, contributing to improved tool life and steady dimensional control. The 4.00 mm plate thickness and standard CNMA geometry ensure compatibility with common toolholder systems, facilitating quick index changes and minimising setup time on the shopfloor. Designed specifically for cast-iron productivity This insert is tuned for the demands of ISO group K materials: abrasive surfaces and frequently breaking chips. The combination of grade, coating and chipbreaker makes it particularly suitable for grey cast iron and similar substrates where abrasive wear is a common concern. For users planning batch production or continuous turning of cast-iron components, this solution offers a balance of process reliability and economical cutting performance.

The rhombic 80° shape and 1.2 mm corner radius provide a versatile cutting profile for both roughing and semi‑finishing passes, reducing assortment complexity. Where abrasiveness and short, brittle chips are encountered, this grade provides a cost‑effective balance of wear resistance and fracture toughness, helping to lower overall cost per component. Compatibility and mounting considerations for straightforward integration The ISO designation and seat code align with common toolholder systems, enabling straightforward replacement in standard CNMA pockets. The insert is marked with its CNMA120412-RK5 base designation and the WKK20S grade for unambiguous identification during tool set‑up. When integrating into a production line, confirm holder clearance for rhombic 80° inserts and the recommended clamping torque to retain consistent orientation and repeatability.

CNMA120412-RK7 WKK20S Turning Indexable Insert — Tiger·tec Silver, for cast iron | Walter Tools CNMA120412-RK7 WKK20S is a turning indexable insert designed for reliably machining cast iron in production turning applications CNMA120412-RK7 WKK20S insert, Tiger·tec Silver Optimised for cast iron (ISO group K) Rhombic 80° form, 1.2 mm nose radius Negative 0° rake, RK7 chipbreaker for reliable chips Consistent wear control for cast iron turning The combination of Tiger·tec Silver coating and the WKK20S grade provides outstanding wear resistance under the abrasive conditions typical of cast iron. The coating system reduces flank wear and maintains edge strength over longer tool life, which translates into fewer index changes and higher productive cutting hours. The supplied chip control geometry, marked RK7, is tuned to produce short, controllable chips with cast materials, reducing the risk of unexpected chip jams and improving process stability on serial turning operations. Geometry that balances strength and surface quality The Rhombic 80° profile with a 1.2 mm nose radius gives a robust cutting edge while still permitting a good surface finish on cast iron components. A larger nose radius supports higher feed rates with reduced vibration, whereas the defined corner radius protects the edge from impact and abrasive wear. The negative 0° rake offers additional rigidity in interrupted cuts and hard zones often encountered in castings, so the toolholder-insert system remains stable during heavy-duty turning cycles. Productivity gains and predictable performance For production shops machining cast iron, the insert’s combination of coated carbide substrate and tailored chipbreaker reduces downtime and contributes to reproducible results. The WKK20S grade is formulated specifically for ISO group K materials, giving shops reliable cutting parameters and predictable tool life. Process planners benefit from straightforward grade assignment and easier optimisation of cutting speeds and feeds, which supports higher throughput and consistent component quality in both batch and continuous manufacture.
