VNMG160408-MP5 WPP20G indexable turning insert, Rhombic 35°, Tiger-tec Gold – Walter Tools

The VNMG160408-MP5 WPP20G is an indexable turning insert designed for machining steel, offering a coated carbide grade with a Rhombic 35° face and a 0.8 mm corner radius

• Tiger-tec Gold coated WPP20G grade
• Optimised for steel machining (ISO P)
• Rhombic 35° geometry for stable cutting
• 0.8 mm corner radius for consistent chip control

Increase throughput with a durable cutting grade

The coated carbide WPP20G grade from the Tiger-tec Gold family is engineered to deliver consistent performance under the thermal and mechanical stresses typical of steel turning. By combining a wear-resistant coating with a geometry optimised for general-purpose steel work, the insert offers longer tool life and fewer indexings per component, which directly supports higher machine utilisation and lower per-part tooling cost. The VNMG form provides a stable cutting edge for a range of turning operations while the MP5 chipbreaker assists in maintaining repeatable chip formation for unattended cycles.

Predictable chip control and improved surface finish

A controlled chip flow reduces interruptions and secondary operations. The MP5 chipbreaker and the 0.8 mm corner radius are coordinated to produce short, manageable chips in typical steel alloys (ISO P), lowering the risk of built-up edge and improving surface integrity. The Rhombic 35° shape helps to spread cutting forces, reducing vibration and supporting a consistent finish. For operators less familiar with chipbreaker technology: the chipbreaker geometry leverages small changes in rake and contact to break chips reliably and protect the cutting edge during the cut.

Robust geometry for demanding and interrupted cuts

The insert’s negative rake 0° configuration increases edge strength and resistance to shock loads, making it suitable for heavier depths of cut and interrupted cuts where positive-rake options could fail prematurely. Being optimised for steel machining, this solution balances cutting performance and durability so that milling or turning cycles remain predictable. The combination of a coated substrate and reinforced edge preparation means fewer unplanned changeovers and a higher degree of process security on shop-floor operations.

Simple integration and predictable handling in the workshop

The insert follows common VNMG dimensional standards (size code 16, thickness code 04) and tolerance class M, enabling straightforward integration into existing tool holders. The standardised form factor reduces setup time and ensures compatibility with conventional clamping systems. Walter Tools’ series design and production consistency mean replacement inserts are interchangeable and reproducible, which supports planning for consumable stock and process normalisation across multiple machines.

FAQ

What materials is this insert best suited for?
The VNMG160408-MP5 WPP20G from Walter Tools is optimised for steel machining (ISO P), including both unalloyed and alloyed steels.

How does the MP5 chipbreaker affect machining?
The MP5 chipbreaker on the Walter Tools insert improves chip control and reduces built-up edge, helping to maintain a consistent surface finish and reliable cycle times.

Is the negative 0° rake suitable for interrupted cuts?
Yes, the 0° negative rake increases edge strength, making the insert appropriate for interrupted and heavier cuts where shock resistance is needed.

What influence does the 0.8 mm corner radius have on performance?
A 0.8 mm corner radius balances edge robustness with surface quality; it supports improved tool life while still delivering acceptable finishes in turning operations.

Can this insert be used in standard VNMG tool holders?
The VNMG160408-MP5 form follows conventional VNMG dimensions and tolerance class M, which allows use in standard holders designed for this insert type.
