SNMG120408-MP3 WPP30G – Indexable turning insert for Stahl, Tiger·tec Gold by Walter Tools

The SNMG120408-MP3 WPP30G is a square 90° indexable insert in the Tiger·tec Gold series, designed for productive and reliable turning of Stahl components in industrial machining.

• Tiger·tec Gold coating for long tool life
• MP3 chipbreaker optimised for Stahl machining
• 0.8 mm corner radius for robust edge strength
• Square 90° form, 12 mm inscribed circle

Extended tool life through Tiger·tec Gold technology

The coated carbide grade from the Tiger·tec Gold series, designated WPP30G, is formulated for a broad range of Stahl applications and engineered to resist wear under the thermal and mechanical loads typical of turning. As a result, the cutting edge offers extended life and predictable performance, reducing tool-change frequency and supporting higher productivity. The combination of coating and grade provides a balance between wear resistance and toughness, making the insert suitable for stable high-volume production.

Secure chip control and stable cutting under load

The MP3 chipbreaker is optimised for controllable chip formation when machining Stahl, improving evacuation and reducing the risk of chip-related interruptions. The insert’s 0° (negative) rake angle enhances edge stability in heavier turning operations, while the 0.8 mm corner radius provides a reinforced cutting edge that tolerates intermittent cuts and slight tool engagements. Together these features support consistent surface quality and reduced rework.

Predictable integration and dimensional reliability

Dimensional conformity is ensured by tolerance class M, enabling reliable indexability and interchangeability in standard toolholders. The insert’s 12 mm inscribed circle and 4.0 mm thickness match common holder specifications, so the component can be integrated into existing tool sets with minimal adjustment. Suitability for ISO group P (Stahl: unalloyed and alloyed) is confirmed by the grade selection, delivering consistent process results in serial production and one-off machining alike.

FAQ

Which materials is this insert intended for?
The SNMG120408-MP3 WPP30G is intended for Stahl machining and is optimised for unalloyed and alloyed Stahl in accordance with ISO group P.

How does the MP3 chipbreaker affect machining performance?
The MP3 chipbreaker on the SNMG120408-MP3 WPP30G promotes controlled chip formation when machining Stahl, improving evacuation and reducing the likelihood of chip-related interruptions.

Is the insert suitable for interrupted cuts?
Yes, the 0.8 mm corner radius and the negative rake angle increase edge robustness, making the insert appropriate for applications with occasional interruptions.

What dimensional data should be checked before ordering holders?
Check the inscribed circle (12 mm), thickness (4.0 mm) and the square 90° form to ensure compatibility with the chosen toolholder and clamping system.

What does tolerance class M mean for production use?
Tolerance class M indicates medium dimensional tolerance, supporting reliable indexability and predictable performance when replacing inserts in production environments.
