TNMG270608-MP5 WPP20G — Indexable turning insert for steel, Tiger·tec Gold | Walter Tools

The TNMG270608-MP5 WPP20G is an indexable turning insert engineered for productive steel machining, combining a tough coated carbide grade with a controlled-chip MP5 geometry for versatile external turning

• Tiger·tec Gold coating for extended tool life
• MP5 chipbreaker for consistent chip control
• Triangle 60° geometry for versatile turning
• Optimised for steel machining (ISO P)

Boosted productivity with durable coating and grade

The combination of the Tiger·tec Gold coating and the WPP20G grade provides a high level of wear resistance and thermal stability under typical steel cutting conditions. This results in longer tool life and fewer insert changes, which supports a steady production rhythm and reduces downtime. The coated carbide composition is optimised for the heat and chip characteristics of steels, so the insert maintains cutting-edge integrity over longer cutting intervals and offers predictable performance in medium to high cutting speeds.

Stable cutting behaviour through geometry and chip control

The MP5 chipbreaker is designed for reproducible chip formation when machining steels classified in ISO group P, producing short, manageable chips under a range of cutting parameters. The triangle 60° insert form delivers three cutting edges per indexable insert, improving cost efficiency, while the 0° (negative) free angle and a 0.8 corner radius increase robustness for heavier cuts and interrupted turning. Explaining the terms: a negative free angle makes the insert more rigid at the cutting edge, helping to withstand shock loads; the corner radius influences surface finish and component strength at the machined edge.

Selection guidance and process assurance for workshop use

Tolerance class M, the established geometry and the series’ focus on steel make this insert a practical choice for general turning operations where consistent surface quality and tool life are required. The insert’s designation and chipbreaker allow for straightforward parameter setting on lathes and turning centres; when optimising feeds and speeds, expect improved process security and repeatability. For complex parts or specialised materials outside standard steel, technical advice is available to match the right insert grade and machining strategy to the application.

FAQ

Which materials is this insert primarily suited to machine?
The TNMG270608-MP5 WPP20G is designed for machining steels (ISO group P), with the WPP20G grade optimised for the heat and chip formation characteristics of unalloyed and alloyed steels.

What advantages does the Tiger·tec Gold coating bring?
Tiger·tec Gold enhances thermal resistance and wear performance on Walter Tools inserts, allowing higher cutting speeds and extended tool life compared with uncoated grades, which supports consistent productivity.

How does the MP5 chipbreaker affect machining?
The MP5 chipbreaker produces reliably broken chips and stable material flow during cutting, reducing the risk of long, entangling chips and simplifying chip handling in turning operations.

Why choose a triangle 60° insert geometry?
Triangle 60° inserts provide three usable cutting edges per insert, improving cost efficiency and versatility for various turning tasks; the geometry also supports good access to contours and profiles.

What does the 0° (negative) free angle mean for daily use?
A 0° (negative) free angle increases edge support and resistance to impact, making the insert suitable for heavier cuts and interrupted cuts where edge robustness is important.
