TNMG110308-MP3 WPP20G indexable turning insert — Tiger·tec Gold, for steel, Walter Tools

TNMG110308-MP3 WPP20G is an indexable turning insert designed for productive steel machining, featuring the Tiger·tec Gold grade and an MP3 chipbreaker for reliable chip control

• Tiger·tec Gold coated carbide grade WPP20G
• MP3 chipbreaker for controlled chip formation
• Triangle 60° insert with 0.8 mm corner radius
• Negative 0° clearance for stable turning

Consistent chip control that reduces interruptions and improves process reliability

The combination of the MP3 chipbreaker and the Tiger·tec Gold technology yields controlled chip formation, minimising interruptions caused by erratic chips during turning operations. The chipformer is tuned for the thermal and mechanical behaviour typical of machining steel, which means fewer stoppages for chip clearing and a smoother process flow. This leads to more predictable cycle times and supports a higher level of process reliability on the shop floor.

Long tool life and wear resistance for economical batch machining

The WPP20G grade is a coated carbide designed for a balanced performance: wear resistance for extended life with sufficient toughness for a range of steel types. The coating reduces flank wear and increases resistance to abrasive conditions, which translates into longer intervals between index changes and lower tooling costs per part. For operations where repeatability and uptime matter, the insert’s construction delivers measurable gains in productivity and economy.

Stable geometry for repeatable surface quality and dimensional accuracy

The triangular geometry with a 60° point angle and the 0.8 mm corner radius provide a robust cutting edge that contributes to consistent surface finish and dimensional control. The negative 0° clearance enhances rigidity in the cutting zone, which is beneficial for interrupted cuts and heavier cross-sections. These geometric features support reliable results on a variety of steels and help maintain part tolerances across extended runs.

Practical compatibility and straightforward integration into existing toolholders

The insert follows the ISO-based designation and fits standard toolholders that accept TNMG-style inserts, making arrival into existing tool setups uncomplicated. The insert size 11 and listed thickness 03 correspond with common TNMG dimensions, enabling a quick exchange and minimising setup effort. The Walter Tools grade is suitable for conventional turning strategies, and the coated carbide substrate allows adaptation to different cutting parameters without sacrificing performance.

FAQ

What materials is this insert suited for?
The TNMG110308-MP3 WPP20G insert is optimised for steel applications (material group P) and performs reliably across a wide range of unalloyed and alloyed steels.

How does the Tiger·tec Gold coating affect performance?
The Tiger·tec Gold coating increases wear resistance and thermal stability, improving the insert’s service life and maintaining cutting-edge integrity under typical steel machining conditions.

What are the main benefits of the MP3 chipbreaker?
The MP3 chipbreaker ensures controlled chip formation, which reduces the risk of entanglement, improves surface quality and decreases downtime for manual chip removal.

Is the insert compatible with standard TNMG toolholders?
Yes, the ISO-based TNMG designation means the insert fits standard TNMG toolholders; check holder compatibility with insert thickness and seat geometry before mounting.

Can this grade be used for interrupted cuts?
The triangular geometry and negative 0° clearance provide added rigidity, making the insert suitable for interrupted cuts and applications requiring a robust cutting edge.
