SPGT1204EDR-F55 WKP35S — Milling indexable insert (Square 90°, 11° clearance) by Walter Tools

SPGT1204EDR-F55 WKP35S is a coated carbide milling insert engineered for robust performance in machining steel and cast iron

• Tiger‑tec Silver coating for wear resistance
• Grade WKP35S for steel and cast iron
• Square 90° insert with 11° clearance
• Chipbreaker F55 for controlled chip formation

Consistent productivity through advanced coating and grade

The combination of Tiger‑tec Silver surface engineering and the WKP35S carbide grade delivers high resistance to abrasive wear and thermal load during typical milling cycles. Designed for the machining of steel and cast iron, this coated carbide insert supports steady cutting performance and longer tool life, reducing tool-change frequency and unplanned downtime. The coating technology enhances surface hardness and oxidation resistance, which contributes directly to more predictable process windows and improved component throughput.

Geometry that promotes repeatable surface quality

The insert’s square 90° geometry together with an 11° clearance and chip control geometry F55 ensures stable engagement and reliable chip evacuation. The dimensional designations (size 12, thickness 04) and tolerance class G support precise seating in toolholders and reproducible cutting results across batches. The F55 chipbreaker is optimised to produce short, controllable chips for interrupted or continuous milling in both steel and cast iron, which improves surface finish and reduces the risk of rework.

Application guidance for efficient machining

This indexable solution is suitable for a wide range of milling strategies where productivity and tool life are priorities. The insert integrates into standard milling holders compatible with its size and form, and its engineered chip control contributes to safer swarf handling and reduced machine idle time. For operations demanding consistent edge life and process security, the Tiger‑tec Silver series offers a balance of wear resistance and edge stability that supports repeatable production results. For detailed cutting parameters and feed/speed recommendations tailored to specific materials and machines, Metav Werkzeuge can provide the necessary data.

FAQ

Which materials are recommended for this insert?
The SPGT1204EDR‑F55 WKP35S insert is designed primarily for steel and cast iron, matching the P and K designations of ISO 513 for reliable chip formation and wear behaviour.

What advantages does the Tiger‑tec Silver coating provide?
The Tiger‑tec Silver surface treatment increases thermal and abrasive resistance, helping the WKP35S grade maintain edge stability and extend tool life under typical milling loads.

How does the F55 chipbreaker affect machining?
The F55 chipbreaker produces short, controlled chips that aid in swarf management and improve surface finish, especially when machining interrupted cuts or materials prone to brittle chips.

Is the insert suitable for finishing operations?
With its stable geometry and tolerance class G, the insert supports consistent contact and can be employed for finishing where toolholder rigidity and correct cutting data are ensured.

What geometric features ensure repeatability?
The square 90° form, 11° clearance and the specified size/thickness codes (12 / 04) contribute to exact seating in toolholders and reproducible cutting conditions across tool batches.
