VBMT160404-MP4 WPP20G turning insert (rhombic 35°, Tiger·tec Gold) by Walter Tools

The VBMT160404-MP4 WPP20G is a rhombic 35° turning insert intended for steel machining, featuring a Tiger·tec Gold coated grade for broad productivity across general turning tasks.

• Tiger·tec Gold coated WPP20G
• Optimised for steel (ISO group P)
• Rhombic 35° form with 5° clearance
• MP4 chipbreaker and 0.4 mm radius

Reliable wear resistance for productive steel turning

The Tiger·tec Gold coating combined with the WPP20G grade ensures consistent wear resistance during extended cutting cycles. Designed specifically for the ISO P group (steel), this coated carbide grade balances toughness and hardness to cope with the heat and chip formation typical of steel machining. The result is fewer unscheduled insert changes and better process stability on serial operations. For operators seeking predictable tool life, this grade reduces variance between runs and supports higher overall productivity.

Geometry tailored for controlled chips and surface quality

The rhombic 35° plate form together with the MP4 chipbreaker provides effective chip control across a wide range of turning conditions. The small 0.4 mm corner radius helps deliver a fine surface finish on external profiles and shoulders while maintaining edge strength for light to medium engagement. A 5° clearance angle reduces rubbing and minimises thermal load on the cutting edge, supporting consistent part quality and reducing the need for secondary finishing operations.

Improved machine uptime and process security

A tolerance class of M and the proven insert format support repeatable seating and indexing on compatible toolholders, which shortens changeover times and reduces set‑up variability. The universal character of the insert avoids frequent grade swaps between roughing and finishing on mixed batches of unalloyed and alloyed steels. Fewer interruptions for tooling changes and stable cutting behaviour contribute to lower unit costs per component and a more reliable shop‑floor workflow.

Practical notes on applications and selection

This insert is optimised for steels (ISO group P) and is suited to both general turning and finishing tasks where a balance of edge life and surface quality is required. The MP4 chipbreaker performs well at moderate feeds and depths; for heavy roughing a different chipbreaker geometry may be preferred. When specifying holders, ensure compatibility with the VBMT16 size and that clamping provides stable support to exploit the full potential of the coated grade.

FAQ

What materials is this insert suitable for?
The VBMT160404-MP4 WPP20G is formulated for ISO group P, i.e. machining of unalloyed and alloyed steel, and the Tiger·tec Gold grade supports common steel turning applications.

How does the MP4 chipbreaker affect performance?
The MP4 chipbreaker offers controlled chip formation for a range of feeds, improving evacuation and contributing to consistent surface finish when using the VBMT160404-MP4 insert.

Is the 0.4 mm corner radius suitable for finishing?
Yes, the 0.4 mm radius balances edge strength with the ability to produce a fine finish; it is well suited to light finishing passes and profile work.
