TNMG160412-MP3 WPP30G — Indexable turning insert, Tiger‑tec Gold (Walter Tools)

The TNMG160412-MP3 WPP30G is a triangular indexable turning insert engineered for productive steel machining, combining a coated carbide grade and an MP3 chipbreaker for consistent performance

• Tiger·tec Gold coating for stable edge life
• WPP30G grade optimised for steel machining
• MP3 chipbreaker for reliable chip control
• Triangle 60° geometry, 1.2 mm corner radius

Predictable edge life for more efficient production

The coated carbide grade WPP30G, part of the Tiger‑tec Gold series, delivers stable edge life and high process reliability in steel turning. The combination of coating technology and substrate composition reduces flank wear and maintains cutting performance over longer periods, which helps to keep cycle times predictable and tool-change intervals extended. This stability supports planning in serial production and reduces unplanned machine downtime, contributing directly to improved throughput and consistent part quality.

Controlled chip formation reduces machine downtime

The integrated MP3 chipbreaker is designed for dependable chip control when machining steels according to ISO group P. By shaping chips into manageable segments and directing them away from the cutting zone, the insert reduces the risk of chip re-cutting and tool breakage. The practical benefit is safer turning operations and lower demands on secondary chip-handling systems, meaning fewer interruptions to production and a simpler set-up for automated or manual turning centres.

Geometry and dimensions that suit precise turning tasks

The triangular 60° geometry with a 1.2 mm corner radius and 4 mm thickness provides a balance between rigidity and versatility. The geometry supports both finishing and light to moderate roughing operations and offers three usable cutting edges per index, which improves cost efficiency per insert. The 0° (negative) rake orientation gives enhanced edge strength for interrupted cuts and tougher steel grades, making the insert a practical choice where robustness and repeatable results are required.

Application focus and process advantages

Designed specifically for steel applications, this indexable cutting insert supports a wide range of common unalloyed and alloyed steels. The WPP30G grade addresses the thermal and chip-formation characteristics typical of steel turning, offering a versatile solution across workshop tasks. For shops seeking reliable performance without constant regrinding, the insert’s combination of coating, chipbreaker and geometry translates into easier process parameter transfer and fewer trial cycles during process development.
