CNMG160616-RP7 WKP30S — Indexable turning insert, Rhombic 80°, 1.6 mm radius | Walter Tools

The CNMG160616-RP7 WKP30S is an indexable turning insert designed for precision turning applications in unalloyed and alloyed Stahl and Gusseisen, combining a coated carbide grade with a dedicated chipbreaking geometry.

• Tiger·tec Silver coated carbide
• RP7 chipbreaker for controlled chips
• Rhombic 80° form, 1.6 mm corner radius
• 0° negative rake for stable cutting

Stable chip control and longer tool life for demanding turning

The combination of the Tiger·tec Silver coating and the WKP30S grade provides enhanced wear resistance and thermal stability, making the insert well suited to continuous production. The integrated RP7 chipbreaker promotes predictable chip formation, which reduces downtime caused by irregular chips and supports unattended turning cycles. For operations where consistent surface quality and tool life matter, this insert offers a balance of durability and machining reliability that helps maintain steady cycle times.

Geometry engineered for repeatable accuracy and secure seating

The rhombic 80° form and the 1.6 mm corner radius deliver a versatile cutting geometry that supports both roughing and finishing passes with controlled cutting forces. The 0° (negative) free angle increases edge strength and enhances stability in interrupted cuts or heavy engagement, while the M tolerance class ensures repeatable seating and interchangeability in toolholders. This geometry reduces the risk of edge chipping and helps maintain dimensional consistency across workpieces.

Application guidance and process benefits for Stahl and Gusseisen

Designed according to ISO material group guidance, the insert targets machining of P (Stahl) and K (Gusseisen) materials: the grade adapts to the thermal and abrasive conditions typical of these groups. In practical terms, this means improved performance on unalloyed and alloyed steels as well as various cast irons. The coated carbide substrate supports higher sustained cutting rates and contributes to lower tooling costs per component through extended tool life and dependable performance.

Productive integration into established turning processes

The insert’s standardised dimensions and grade make it straightforward to integrate into existing tooling systems. The robust grade and coating strategy help reduce the frequency of tool changes and support consistent surface finishes across batch production. Combined with a suitable cutting data sheet and toolholder selection, the insert can contribute to measurable process stability and predictable maintenance intervals.

FAQ

What materials is this insert suitable for?
The CNMG160616-RP7 WKP30S is configured for machining P (Stahl) and K (Gusseisen) material groups, offering wear resistance and chip control appropriate for steels and cast irons.

How does the RP7 chipbreaker influence machining?
The RP7 chipbreaker promotes controlled, short chips and improves evacuation in turning, which helps maintain steady cycle times and reduces manual chip handling.

What advantages does the Tiger·tec Silver coating provide?
The Tiger·tec Silver coating increases thermal stability and wear resistance, enabling longer tool life under continuous or demanding cutting conditions.

Is the insert suitable for interrupted cuts or heavy engagement?
Yes; the 0° negative free angle and the robust grade improve edge strength and stability in interrupted cuts and heavier material removal.

Which insert geometry is this and what does it mean for toolholders?
The rhombic 80° form is a common indexable geometry that fits standard toolholders designed for CNMG-style inserts, supporting straightforward replacement and repeatable seating.
