VBMT160408-MP4 WPP20G Walter Tools – turning indexable insert, Tiger·tec Gold coating for steel

The VBMT160408-MP4 WPP20G is a rhombic 35° turning insert designed for machining steel, offering reliable chip control and extended service life with the Tiger·tec Gold technology.

• Tiger·tec Gold coating for long tool life
• MP4 chipbreaker for stable chip formation
• Rhombic 35° form with 0.8 mm nose radius
• Optimised for steel (ISO P)

Maximise productivity in steel turning with reliable coating technology

The combination of Tiger·tec Gold technology and a wear-resistant geometry delivers measurable productivity gains in steel machining. The advanced coating reduces flank wear and sustains cutting-edge integrity under typical steel cutting temperatures, so cycle times remain stable and tool-change frequency is reduced. In practice this means more consistent component dimensions and fewer interruptions for tool replacement, supporting continuous production workflows. The insert’s balanced design focuses on efficient heat management and edge stability, which benefits both short-run and series production.

Consistent chip control for improved surface finish and safety

Equipped with the MP4 chipbreaker and a Rhombic 35° shape, this insert promotes predictable chip formation and evacuation when turning steel. The 0.8 mm nose radius provides a compromise between strength and surface quality: the radius helps maintain dimensional stability while enabling a good surface finish on turned parts. Predictable chips lower the risk of entanglement and reduce the need for secondary cleaning operations, contributing to a safer and cleaner machining environment and a more reliable downstream process.

Robust, repeatable performance through coated carbide grade

The WPP20G grade is a coated carbide formulation tailored for steel applications and belongs to the Tiger·tec Gold family. As a coated carbide insert it offers a broader wear window and good resistance to abrasive conditions commonly encountered in steel turning. The tolerance class M and solid geometry ensure repeatable mounting and stable cutting over multiple indexing cycles, supporting consistent part tolerances across batches. This robustness translates into predictable maintenance intervals and simplified tool inventory planning.

Clear application profile and handling recommendations

Designed primarily for steels (ISO group P), the insert suits a range of turning tasks from medium-duty roughing to semi-finishing where chip control and tool life are priorities. The insert dimensions (16 mm size, 4.0 mm thickness) and the 5° relief angle support versatile clamping in common toolholders; the rhombic 35° form facilitates effective approach angles for a variety of turning contours. For best results, match feed and depth of cut to the chosen grade and machine rigidity; the MP4 chipbreaker performs especially well when stable cutting conditions are maintained. If further machining parameters are required, technical advice is available.

FAQ

Which materials is this insert suitable for?
The VBMT160408-MP4 WPP20G is designed primarily for steel (ISO group P); the WPP20G grade is optimised to handle the typical heat and chip characteristics of unalloyed and alloyed steels.

What is the nose radius and why does it matter?
This insert has a 0.8 mm nose radius, which balances edge strength with surface finish capability; a modest radius like this helps maintain dimensional accuracy while still achieving good surface quality during turning.

How does the MP4 chipbreaker improve machining?
The MP4 chipbreaker ensures reliable chip control for steel cutting, promoting short, segmented chips that evacuate cleanly and reduce the risk of chip-related interruptions or part damage when using Walter Tools inserts.

Can this insert be used for finishing operations?
Yes—due to its coated carbide grade and geometry, the insert is suitable for medium to fine turning where consistent surface finish and dimensional repeatability are required, provided cutting conditions and machine rigidity are appropriate.

What are the key mounting and handling considerations?
Use toolholders compatible with a rhombic 35° plate form and secure clamping to preserve the tolerance class M accuracy; the plate dimensions (16 mm × 4.0 mm) match common holders for standard turning tasks.
