CNMG160612-RP7 WKP30S indexable turning insert — Walter Tools — Tiger·tec Silver, RP7 chipbreaker

CNMG160612-RP7 WKP30S is an indexable turning insert designed for precise and productive turning operations on steel and cast iron components

• Tiger·tec Silver coating for long tool life
• RP7 chipbreaker for controlled chip formation
• Rhombic 80° form with 1.2 mm corner radius
• Optimised for steel and cast iron machining

Durable coating for consistent tool life and economy

The Tiger·tec Silver technology and the WKP30S grade combine to provide a coated carbide substrate that is optimised for the thermal and abrasive conditions found when machining steel and cast iron. The coating reduces flank wear and helps maintain a stable cutting edge over longer cycles, which translates into fewer tool changes and lower unit costs in batch production. These material and coating choices are reflected in reproducible tool life and predictable process windows.

Predictable chips and surface quality through geometry

The RP7 chipbreaker is engineered to produce short, controllable chips when paired with the rhombic 80° insert form and 0° (negative) relief angle. A corner radius of 1.2 mm provides edge robustness and supports consistent surface finish during medium to heavy cuts. The combination of chip control and edge strength reduces the likelihood of built-up edge and improves repeatability, especially in interrupted cuts or mixed material runs.

Clear mounting and ISO-compliant geometry for fast tool changeover

The insert follows the CNMG geometry standard, which allows use in any toolholder designed for CNMG inserts; the designation CNMG160612-RP7 also indicates the insert shape and nominal dimensions. Tolerance class M and execution G ensure consistent interchangeability in production setups. Thickness code 06 and size 16 correspond to common holder systems and are documented for process planning and tool balancing in machining centres.

Process reliability backed by brand engineering

Walter Tools’ design focus on stable edge preparation and modern grades supports reliable machining results across a broad material spectrum. The combination of a proven chipbreaker, a robust rhombic form and a high-performance coating means less unplanned downtime and more consistent part quality. For production environments where throughput and repeatability are priorities, this insert contributes to a measurable improvement in process stability and workpiece finish.

FAQ

What materials is this insert suitable for?
The CNMG160612-RP7 WKP30S insert is designed for machining steel and cast iron, following the ISO 513 material groups P and K as indicated by the grade characteristics.

Is WKP30S a coated carbide grade?
Yes, WKP30S is a coated carbide grade within the Tiger·tec Silver family, optimised for wear resistance and thermal stability during metal cutting.

What does the RP7 chipbreaker provide in practice?
The RP7 chipbreaker promotes short, controlled chips and improves chip evacuation, which supports safer machining and better surface quality on typical turning operations.

Which toolholders accept this insert geometry?
The CNMG geometry fits standard toolholders designed for CNMG inserts; the CNMG160612 designation indicates compatibility with holders made for that ISO form and size.

How does the 1.2 mm corner radius influence cutting performance?
A 1.2 mm corner radius increases edge strength for more robust cutting during heavier passes and contributes to improved surface finish stability compared with smaller radii.
