TNMG220412-MP3 WPP20G – indexable turning insert, triangle 60°, for steel | Walter Tools

TNMG220412-MP3 WPP20G is an indexable turning insert designed for robust steel machining applications, featuring the Tiger·tec Gold coating and the MP3 chipbreaker for controlled chip formation.

• Tiger·tec Gold coated carbide grade WPP20G
• MP3 chipbreaker for reliable chip control
• Triangular 60° form with 1.2 mm corner radius
• Relief angle 0° (negative) for stable cutting

Safer process control through optimised chip formation

The MP3 chipbreaker in this insert is designed to manage chips effectively during turning of steel, reducing the risk of long swarf and improving operator safety. Combined with the Tiger·tec Gold coating and the WPP20G grade, the insert provides consistent edge strength and wear resistance under the thermal and mechanical loads typical for P‑class materials according to ISO 513. The result is improved process reliability and fewer interruptions for chip clearing, which supports higher productivity on turning centres.

Geometry built for durability and repeatable performance

The triangular 60° form offers three usable cutting edges per insert, helping to reduce tooling costs through efficient edge indexing. The 1.2 mm corner radius increases edge robustness for heavier cuts and interrupted operations, while the 0° (negative) relief angle provides greater stability and resistance to edge chipping. These geometric choices deliver predictable tool behaviour and make the insert suitable for a wide range of turning tasks where tool life and repeatability matter.

Specifically tuned for steel applications

This insert is specified for the machining of steel (material group P) and its coated carbide composition is engineered to handle the heat and chip formation characteristics of unalloyed and alloyed steels. The WPP20G grade balances wear resistance and toughness, making it a universal option across many steel grades rather than a niche, application-specific grade. For production environments seeking a single, reliable grade for general steel turning, this insert reduces the need for frequent grade changes.

Integration into production — compatibility and handling benefits

The standard ISO designation ensures straightforward procurement and toolholder compatibility on most turning setups. Using a recognised geometry and chipbreaker such as TNMG220412-MP3 WPP20G simplifies inventory management and supports quick replacement strategies, reducing machine downtime. The coated grade and robust form also contribute to longer intervals between tool changes, which lowers handling time and improves overall machining throughput.

FAQ

What materials is this insert suitable for?
The TNMG220412-MP3 WPP20G is designed primarily for steel machining (ISO group P) and its WPP20G grade and Tiger·tec Gold coating are tuned to the thermal and chip‑forming behaviour of steels.

How does the MP3 chipbreaker improve machining?
The MP3 chipbreaker on the TNMG220412-MP3 WPP20G shapes chips to prevent long swarf and to facilitate stable evacuation, which enhances process reliability during turning operations in steel.

How many cutting edges are available per insert?
The triangular 60° form provides three usable cutting edges, allowing quick indexing and economical use of each insert in production.

Is this insert suitable for interrupted cuts?
Yes; the 1.2 mm corner radius and the negative 0° relief angle on the TNMG220412-MP3 WPP20G increase edge strength and stability, improving resistance to chipping during interrupted cutting.

Which manufacturer produces this insert?
This insert is supplied by Walter Tools and specified as TNMG220412-MP3 WPP20G for steel applications.
