SNMG120408-RP5 WPP30G Walter Tools turning insert — Tiger‑tec Gold coating, square 90° form

The SNMG120408-RP5 WPP30G is a square turning insert designed for robust steel machining applications, combining a coated carbide grade with a dedicated chipbreaker for consistent productivity.

• Tiger·tec Gold coated for long tool life
• Optimised grade WPP30G for steel (ISO P)
• Square 90° form with 0.8 mm corner radius
• RP5 chipbreaker for reliable chip control

Boosted productivity for steel machining

The combination of the WPP30G grade and Tiger‑tec Gold coating delivers higher wear resistance and thermal stability during typical steel turning operations (ISO P). The coated carbide substrate sustains cutting-edge integrity under elevated temperatures, which reduces flank wear and extends tool life. By favouring steady wear rather than unpredictable edge failure, shops can plan longer tool cycles and achieve more consistent component tolerances, supporting a measurable improvement in machine uptime and process efficiency.

Robust geometry that balances strength and finish

A square 90° plate with a 0.8 mm corner radius offers a compromise between edge strength and surface quality: the larger radius improves edge robustness for interrupted cuts and semi‑finishing, while still allowing acceptable surface finishes on steel. The negative rake 0° clearance stabilises chip formation in heavier cuts and supports effective power transfer through the holder. The integrated RP5 chipbreaker is engineered for predictable chip control on ISO P alloys, reducing the need for manual chip handling and lowering the risk of recutting or tool interference.

Consistent performance and practical application notes

This insert is intended primarily for steel applications and is suited to a wide range of turning tasks from medium‑roughing to finishing when cutting parameters are adjusted accordingly. The plate’s tolerance class M ensures interchangeability in standard toolholders; the common dimensions (12 mm size, 4 mm thickness) simplify inventory management across production cells. For optimised results, pair the insert with a rigid toolholder and consult manufacturer cutting data for recommended feeds and speeds to secure process security and repeatable surface quality.

FAQ

What materials is this insert intended for?
This turning insert is designed for machining steels and is classified for ISO P applications; the WPP30G grade is optimised for the thermal and chip‑formation behaviour typical of steel.

Can the insert be used for finishing operations?
Yes — with appropriate cutting parameters the square 90° form and 0.8 mm corner radius produce acceptable surface finishes; adjust feed and speed based on the insert’s Tiger‑tec Gold coating properties.

How does the RP5 chipbreaker affect machining?
The RP5 chipbreaker promotes stable chip control on steel, producing short, manageable chips that reduce recutting and improve safety in automated turning operations.
