TNMG220408-MP5 WPP20G turning insert — for steel, Tiger·tec Gold (Walter Tools)

The TNMG220408-MP5 WPP20G is a triangular 60° coated carbide indexable insert designed for general steel turning, offering robust edge stability and reliable chip control for industrial production environments.

• Tiger·tec Gold coating for high productivity
• WPP20G grade optimised for steel turning
• MP5 chipbreaker for controlled chip formation
• 60° triangular insert with 0.8 mm nose radius

Maximised productivity through advanced coating and grade

The combination of the Tiger·tec Gold coating and the WPP20G carbide grade provides enhanced wear resistance and thermal stability tailored to steel machining. This results in prolonged edge life and more consistent component quality across long production runs. The coating technology reduces flank and crater wear under the elevated temperatures typical of steel turning, which translates into fewer tool changes and improved machine uptime. For operations where repeatability and throughput are priorities, these properties support a measurable improvement in process efficiency and lower cost per part.

Consistent chip control and geometry that protects the edge

The MP5 chipbreaker has been developed to produce short, controllable chips in a wide range of turning conditions, reducing entanglement and improving swarf evacuation. The triangular 60° geometry combined with a 0.8 mm nose radius and a 0° (negative) rake angle delivers a balanced compromise between strength and surface finish: the negative rake enhances edge robustness for interrupted cuts, while the modest nose radius maintains dimensional control. Explaining the chipbreaker function: it alters chip formation locally to break the chip into manageable segments, which in practice reduces toolholder vibration and improves workpiece surface integrity.

Application range, tolerance and practical advantages for workshops

Categorised for the ISO P group, the insert is intended primarily for machining steels and is suitable for a broad range of steel grades encountered in production. The tolerance class M and the standardized geometry make the insert straightforward to index and replace, enabling rapid tool replacement workflows and predictable set-ups on conventional and CNC lathes. For production engineers and workshop planners, the clear assignment to steel applications and the Tiger·tec Gold series simplifies tooling decisions and supports process standardisation, helping to ensure consistent results across shifts and operators.

FAQ

What materials is this insert suitable for?
The TNMG220408-MP5 WPP20G is specified for ISO P materials and is optimised for turning steels, offering a balance of wear resistance and toughness for general steel machining.

What advantages does the MP5 chipbreaker provide?
The MP5 chipbreaker promotes short, controlled chips and reliable swarf evacuation, which helps reduce entanglement and improves surface finish and tool life when using the insert.

How does the Tiger·tec Gold coating affect performance?
The Tiger·tec Gold coating increases thermal stability and wear resistance, allowing the insert to maintain cutting-edge integrity under the high temperatures encountered in steel turning, resulting in longer tool life.

What does the 0° (negative) rake angle mean in practice?
A 0° negative rake enhances edge robustness and is beneficial for interrupted cuts or heavier engagement; it trades a small portion of cutting-effort efficiency for improved edge strength and stability.

Is the geometry suitable for precision finishing?
With a 0.8 mm nose radius and a 60° triangle form, the insert supports good dimensional control and acceptable surface quality for many finishing operations while still providing strength for light-to-medium roughing.
