CNMG190616-RP7 WKP30S turning indexable insert — Rhombic 80°, 1.6 mm corner radius | Walter Tools

the CNMG190616-RP7 WKP30S is a negative‑rake rhombic insert engineered for demanding turning applications on Stahl and cast iron

• Tiger‑tec Silver coated carbide grade WKP30S
• Optimised for Stahl (P) and cast iron (K)
• Rhombic 80° insert geometry for versatile turning
• Negative rake, 0° clearance, 1.6 mm corner radius

High productivity through coated carbide technology

The Tiger‑tec Silver coating combined with the WKP30S grade offers enhanced wear resistance and thermal stability, resulting in extended cutting edge life and fewer indexings. Designed for the machining of Stahl and cast iron, this combination reduces flank wear under typical turning temperatures and enables higher cutting speeds without premature degradation. The robust coating technology translates directly into lower tooling costs per workpiece and more consistent component tolerances — a clear productivity benefit for workshop and production environments.

Robust geometry for consistent chip control and surface quality

The rhombic 80° shape with a 1.6 mm corner radius and RP7 chipbreaker provides a balance between strength and finish. The negative rake (0°) geometry increases edge stability for interrupted cuts and heavy radial engagement, while the RP7 chip control reduces long or stringy chips when machining abrasive castings or tougher Stahl grades. The outcome is improved surface finish and reproducible component quality with fewer secondary operations — particularly advantageous for small‑batch and production turning where repeatability matters.

Practical application advantages and integration into tooling systems

Marked as CNMG190616 in conventional indexing systems, the insert matches standard pocket and clamp configurations used in most turning toolholders and is supplied in the Tiger‑tec Silver series for immediate use in production. The insert thickness and tolerance class ensure reliable seating and repeatable positioning; this simplifies tool preparation and reduces set‑up time. For shops seeking a cost‑efficient upgrade to carbide inserts that combine longevity with predictable chip behaviour, this specification supports both finishing and versatile medium‑duty roughing tasks without compromising process stability.

FAQ

What materials is this insert intended for?
The CNMG190616-RP7 WKP30S insert is specified for machining Stahl (group P) and cast iron (group K) according to ISO‑based material classification, making it suitable for a wide range of general engineering parts.

How does the RP7 chipbreaker affect machining behaviour?
The RP7 chip control geometry promotes short, controllable chips in both Stahl and cast iron, improving process stability and minimising chip entanglement at typical turning feeds and speeds.

Is the negative‑rake geometry suitable for interrupted cuts?
Yes, the 0° negative rake increases edge robustness and impact resistance, which is beneficial for interrupted cuts and applications with variable engagement.

Can this insert be used for finishing operations?
With its rhombic 80° form and 1.6 mm corner radius, the insert supports finishing and medium‑duty turning where a fine surface finish and dimensional consistency are required.

What is the insert designation for ordering and tool preparation?
Order under CNMG190616-RP7 WKP30S; the CNMG format and thickness allow compatibility with standard turning holders designed for this insert family.
