Improved tool life and cost-efficiency for steel machining

The coated-carbide Tiger·tec Gold grade WPP20G provides a balance of wear resistance and toughness that reduces tool changes during batch production. Because the grade is optimised for the machining behaviour of steels (ISO group P), the insert maintains a stable cutting edge under typical thermal and mechanical loads, leading to fewer interruptions and a lower total cutting-cost-per-part. This performance advantage is particularly relevant for series production and contract turning where predictable wear and repeatable results matter. The combination of coating technology and substrate composition helps to delay flank and crater wear, translating directly into longer useful life.

Consistent surface quality through engineered chip control

The MP5 chipbreaker and the rhombic 80° geometry are engineered to shape chips reliably and reduce vibration in many turning operations. The modest 1.2 mm corner radius smooths transitions on external profiles and shoulders, improving surface finish without sacrificing edge strength. Controlled chip formation reduces the risk of entanglement and the need for manual chip clearing, which supports a safer, more efficient shopfloor environment. Where surface integrity and repeatable part dimensions are priorities, this insert offers tangible process control benefits.

Secure seating and predictable repeatability for set-ups

Produced to tolerance class M, this CNMG-format insert ensures dimensional consistency and secure clamping in standard toolholders. The designation indicates the insert family and chipbreaker combination, simplifying inventory management and tool change procedures for production teams. The specified 0° negative rake provides a robust cutting edge suitable for a range of cutting conditions, particularly where a stable edge is preferred over aggressive cutting geometry. The standardised form and thickness code facilitate quick indexing and consistent performance across multiple tool stations.

Broad applicability in general turning and finishing operations

Optimised for unalloyed and alloyed steels, this indexable insert supports a wide spectrum of turning tasks from roughing to finishing, depending on machining parameters and holder rigidity. The coated carbide construction gives a degree of versatility across different feed rates and depths of cut, while the MP5 chipbreaker enables reliable chip control in continuous turning. For workshop planners and process engineers seeking a single grade to cover many steel applications, this insert reduces complexity in tool selection and simplifies spare-part stocking.

FAQ

What steels is this insert suitable for?
The CNMG160612-MP5 WPP20G insert with WPP20G grade is optimised for ISO group P steels, covering unalloyed and alloyed steels commonly used in turning.

How does the MP5 chipbreaker affect machining?
The MP5 chipbreaker on this Walter Tools insert promotes controlled chip formation, improving swarf evacuation and helping to maintain a stable surface finish during continuous turning.

What does the 1.2 mm corner radius mean for finishing?
A 1.2 mm corner radius balances edge strength and surface quality; it supports better finish on external profiles while reducing the risk of chipping compared with very small radii.

Is the negative 0° rake suitable for roughing?
The 0° negative rake provides a robust cutting edge that can handle the higher mechanical loads encountered in roughing, while still being applicable for many finishing cuts with appropriate parameters.

Can this insert be indexed in standard CNMG holders?
Yes, the CNMG160612-MP5 WPP20G conforms to CNMG format dimensions and tolerance class M, allowing secure seating and repeatable indexing in standard holders designed for CNMG inserts.
