WCMT030204-E47 WPP20S — Indexable drill/boring insert, Trigon 80°, Tiger·tec Silver (Walter Tools)

WCMT030204-E47 WPP20S is an indexable cutting insert designed for drilling and boring operations in industrial machining, optimised for Stahl components.

• Tiger·tec Silver coated carbide
• Optimised for Stahl machining
• Trigon 80° insert geometry
• 7° clearance angle, 0.4 mm corner radius

Superior wear resistance for continuous production

The Tiger·tec Silver coating combined with the WPP20S grade provides a resilient cutting edge that reduces flank wear and extends usable life. For machining of Stahl (ISO group P), the coated carbide substrate is engineered to withstand the heat and abrasion typical of interrupted cuts in drilling and boring. This results in fewer index changes, lower tooling costs per hole and a more predictable production rhythm. The technical pairing of coating and substrate enables consistent performance across a broad range of alloyed and unalloyed Stahl grades.

Geometry that stabilises cutting and improves surface quality

A Trigon 80° insert form with a 0.4 mm corner radius and 7° clearance has been chosen to balance edge strength and chip formation. The trigon geometry increases contact area for secure seating in the tool holder and promotes predictable chip flow, while the modest corner radius supports good hole-surface finish without compromising edge life. For operators and process engineers this geometry translates into fewer rejects and less rework, particularly in through-hole and step-boring applications where axial and radial forces vary.

Practical benefits for workshop efficiency and process reliability

The insert’s construction—registered as WCMT030204-E47 WPP20S—is tailored for productive chip removal in drilling/boring cycles. The combination of a coated hardmetal grade and the specified geometry reduces cycle interruptions and improves reproducibility. Where short tool-change windows and high part counts matter, this insert contributes to reduced downtime and a lower cost per part. Specifying this insert in stable clamping systems supports a robust cutting process, leading to higher output and a steadier lead time for critical components.

Integration, selection and expert support for machining setups

Selection of the right insert grade and geometry is decisive for process success. The WPP20S grade is a universal, wear-resistant option within the Tiger·tec Silver family, particularly suited to common Stahl machining tasks. For adaptation into an existing toolholder or for optimising feed and speed, Metav Werkzeuge offers consultancy to align cutting data with part material and machine capability. Combining sound technical data with practical advice helps maintain tool life and achieve the required hole tolerances with predictable results.

FAQ

What materials is this insert intended for?
The WCMT030204-E47 WPP20S insert is optimised for the machining of Stahl (ISO group P) and is designed to handle the heat and chip characteristics typical of these materials.

Which features of the insert improve hole quality?
The Trigon 80° geometry combined with a 0.4 mm corner radius and a 7° clearance angle provides stable cutting and controlled chip flow, which supports consistent surface finish in drilling and boring operations.

How does the Tiger·tec Silver coating affect tool life?
The Tiger·tec Silver coating on the WPP20S grade enhances wear resistance and reduces adhesion at the cutting edge, resulting in longer indexed life and more predictable performance during production runs.

Is this insert suitable for high-speed drilling cycles?
The coated carbide construction is engineered for productive machining cycles; process parameters should be matched to machine capability and workpiece Stahl grade to achieve optimal results.
