RDMX12T3M0T-A27 WKP35S indexable milling insert — Walter Tools, Tiger·tec Silver, round 12 mm, 15° clearance

The RDMX12T3M0T-A27 WKP35S is a round indexable milling insert designed for productive machining of steel and cast iron in general milling operations.

• Tiger·tec Silver coating for enhanced wear resistance
• Suitable for steel and cast iron machining
• 15° clearance and round 12 mm form for versatility
• Grade WKP35S with stable chip control

Consistent productivity for steel and cast iron machining

The insert is based on the Tiger·tec Silver coating technology and the WKP35S coated-carbide grade, delivering improved wear resistance and stable performance in demanding conditions. Designed for machining group P (steel) and K (cast iron) according to ISO 513, the geometry and coating combination promotes predictable chip formation and extended tool life, which reduces tool-change frequency and supports a lower cost per part in medium- to high-volume production. The chipbreaker designation A27 helps to control broken chips typical of steel and abrasive cast-iron machining, so machining cycles remain smooth and repeatable.

Compact geometry for flexible cutter integration and process reliability

Featuring a round 12 mm plate form with a 15° free angle and T3 thickness, the insert offers compact geometry that is suitable for multi-edge indexing and versatile cutter designs. The tolerance class M ensures consistent interchangeability within tolerance-sensitive toolholders. Round-form inserts allow multiple cutting edges per index, increasing usable life before regrinding or replacement is required and enabling straightforward mounting strategies for production tooling where space and flexibility are priorities. The execution marked X corresponds to specific nominal dimensions and seating geometry, supporting predictable clearance and cutting engagement.

Durable grade and economical machining for production environments

The WKP35S grade is a modern coated carbide formulation optimised for broad material coverage and reliable edge stability. In practice, this means fewer interruptions from flank or crater wear and a more consistent surface finish across batches. For operations where process stability and repeatability are essential, the insert’s design contributes to reduced scrap rates and less process variation. The combination of coated carbide and an effective chipbreaker reduces the risk of tool-related downtime and supports a more economical machining strategy in mixed steel and cast-iron applications.

FAQ

What materials is this insert intended for?
The RDMX12T3M0T-A27 WKP35S insert is intended for machining steel (P) and cast iron (K) as defined by ISO 513.

How does the Tiger·tec Silver series affect tool life?
The Tiger·tec Silver coating on the WKP35S grade improves wear resistance and edge stability, which typically extends tool life and maintains cutting performance under elevated thermal loads.

What advantages does the round 12 mm form offer?
The round 12 mm form provides multiple indexable cutting edges and flexibility in cutter design; combined with a 15° free angle it supports reliable engagement and consistent chip control.

Which chip control behaviour is expected from this insert?
Chipbreaker A27 is engineered for stable chip formation in steel and cast iron, promoting short, controlled chips and reducing risk of chip entanglement in standard milling operations.

What does the tolerance class M mean for production?
Tolerance class M indicates a medium tolerance level that ensures consistent interchangeability and predictable seating in toolholders, supporting repeatable production quality.
