WNMG080412-RP7 WKP30S — Turning insert for steel and cast iron | Walter Tools

The WNMG080412-RP7 WKP30S is a trigon-shaped indexable turning insert designed for productive machining of steel and cast iron in general turning applications.

• Tiger‑tec Silver coating for wear resistance
• WKP30S grade for steel and cast iron
• 80° trigon form with 1.2 mm radius
• RP7 chipbreaker for stable chip control

Durable coating and grade for extended tool life

The WKP30S cutting grade, implemented within the Tiger‑tec Silver technology, is a coated carbide solution optimised for machining both steel and cast iron in accordance with ISO 513 group designations P and K. The coating reduces adhesive and abrasive wear, which translates into more consistent component tolerances and fewer insert changes in serial production. By favouring predictable wear behaviour, this grade supports improved process economy and less unplanned downtime in machining centres.

Geometry engineered for secure cutting and repeatability

The 80° trigon shape combined with a 0° (negative) clearance geometry provides a robust engagement at the cutting zone, helping to maintain a stable cutting edge under interrupted or heavy cuts. The 1.2 mm corner radius increases strength at the cutting edge and improves surface finish where allowed by component geometry. The RP7 chipbreaker is tuned to produce short, controlled chips on a range of steels and grey irons, aiding automated chip evacuation and lowering the risk of tool damage during continuous operation.

Production advantages and predictable performance

In production environments where repeatability and process security are priorities, this Walter Tools insert offers consistent chip formation and good edge stability for general turning tasks. The combination of grade, coating and chipbreaker reduces the frequency of indexings and tool changes, which supports higher machine uptime and predictable cycle times. For shops seeking an insert that balances productivity with long tool life in mixed steel and cast iron workloads, this insert is a pragmatic choice that aligns with professional machining requirements.

FAQ

Is this insert suitable for stainless steel?
The WKP30S grade of the WNMG080412-RP7 WKP30S insert is specified for steel and cast iron (ISO groups P and K); stainless steel is not listed among the intended primary applications.

What benefits does the Tiger‑tec Silver technology deliver?
Tiger‑tec Silver coating on the WKP30S grade enhances wear resistance and edge stability, which helps the Walter Tools insert maintain dimensional accuracy and extend service life in production turning.

How does the trigon 80° form affect indexing and edge use?
The 80° trigon shape provides multiple usable cutting edges and a stable seating geometry; the form supports efficient indexing and repeatable positioning of the cutting edge in turning operations.

Which chip behaviour is expected with the RP7 chipbreaker?
The RP7 chipbreaker is designed to produce short, controlled chips on a range of steels and grey irons, improving chip evacuation and reducing the likelihood of entanglement during automated machining.
