WOEX040304-E57 WKP35S Trigon 80° indexable insert — Walter Tools, Tiger·tec Silver

A WOEX040304-E57 WKP35S drilling and reaming indexable insert engineered for productive machining of steel and cast iron with a Trigon 80° geometry and Tiger·tec Silver coating.

• Tiger·tec Silver coating for long tool life
• WKP35S coated carbide grade
• Trigon 80° geometry for stable cuts
• 0.4 mm corner radius for edge strength

Greater efficiency through advanced coating technology

The Tiger·tec Silver coating combines a wear-resistant surface with thermal stability, which reduces flank wear and preserves the cutting edge during continuous operation. This results in fewer index changes and less downtime, supporting a higher parts-per-shift output. For jobs dominated by heat generation, such as turning and drilling in P-group steels, the coated grade provides reliable performance and predictable tool life, improving process economy and planning.

Consistent performance for steel and cast iron applications

Designed for ISO groups P (steel) and K (cast iron), the grade WKP35S is tuned to the typical chip formation and abrasive conditions encountered with these materials. The chipbreaker E57 promotes controlled chip flow, reducing the risk of built-up edge and improving surface finish on the workpiece. By matching grade chemistry and coating to the material group, the insert helps maintain consistent component quality across batch production and mixed-series runs.

Geometry that stabilises the machining process

The Trigon 80° form and a 0.4 mm corner radius combine to increase insert rigidity and distribute cutting forces more evenly, which lowers vibration and improves hole quality in drilling or reaming operations. A modest corner radius supports stronger edges without compromising entry behaviour, making the insert a practical choice for interrupted cuts or less rigid setups. The trigon geometry also offers three cutting corners per insert, optimising economy per indexable element.

Practical compatibility and handling guidance

This insert is supplied in the WOEX format (designation WOEX040304-E57) with size 04 and thickness 03, tolerance class E and execution X, suitable for toolholders configured for drilling and bore-enlargement applications. The combination of coated carbide and the E57 chipbreaker provides a good balance between cutting-edge protection and chip control. For optimal results, select feed and speed values aligned with the component material and machine rigidity; for specific holder compatibility or process windows, consult the technical advisers at Metav Werkzeuge.

FAQ

What materials is this insert suitable for?
The WOEX040304-E57 WKP35S insert from Walter Tools is suitable for machining steel (P) and cast iron (K) according to ISO material groupings, offering tailored chip control for both material families.

What does the E57 chipbreaker provide?
The E57 chipbreaker on the WKP35S grade promotes controlled chip formation and evacuation, which helps to maintain surface finish and reduce the likelihood of built-up edge during continuous drilling or reaming.

How does the Trigon 80° geometry benefit drilling operations?
Trigon 80° geometry increases edge strength and rigidity, improving stability in drilling or bore-enlargement tasks; the 0.4 mm corner radius further supports edge durability under moderate engagement.

Is the WKP35S grade coated or uncoated?
The WKP35S is a coated carbide grade within the Tiger·tec Silver technology, combining a wear-resistant surface with thermal robustness for demanding P- and K-group applications.
