WCMT040204-E47 WPP20S drilling/boring indexable insert — Trigon 80°, 7° clearance, Walter Tools

The WCMT040204-E47 WPP20S is a trigon 80° indexable insert engineered for drilling and boring applications, optimised for machining Stahl and tailored to stable chip formation in general-purpose to demanding cutting tasks.

• Tiger·tec Silver coated carbide grade WPP20S
• Trigon 80° geometry for stable engagement
• E47 chipbreaker for controlled chip flow
• 7° clearance angle for reduced rubbing
• 0.4 mm corner radius for durable cutting edge

Improve cycle times with coating and grade synergy

The combination of the Tiger·tec Silver coating and the WPP20S carbide grade delivers a balance between abrasion resistance and toughness that directly improves cycle times. The coating reduces friction at the cutting edge while the substrate maintains edge integrity under intermittent and continuous cutting loads. For machining Stahl, the insert’s geometry and the E47 chipbreaker work together to promote predictable chip formation; this reduces the frequency of interruptions for chip clearing and supports uninterrupted production runs. The result is higher process reliability and fewer tool changes, which has an immediate effect on operational efficiency.

Longer tool life and improved surface quality

A 0.4 mm corner radius and a 7° clearance angle combine to protect the cutting edge during axial engagement and to minimise flank contact. This geometry translates into consistent dimensional accuracy and an improved surface finish on the workpiece. The coated carbide composition of the grade increases resistance to thermal and abrasive wear, meaning the insert sustains its cutting performance over longer runs. Fewer regrinds and replacements reduce downtime and overall operating costs, supporting a favourable cost-per-part metric in batch or continuous production.

Versatile compatibility with common drilling and boring systems

The trigon 80° form and the insert size code support compatibility with a wide range of drill bodies and boring heads designed for indexable inserts. The compact form factor with plate size 04 and thickness 02 enables use in constrained spaces where secure seating and stable cutting are required. The E47 chipbreaker is optimised for the thermal and chip conditions typical when working with Stahl, helping to avoid built-up edge and promoting reliable chip evacuation even in deeper holes or interrupted cuts.

Practical application advice and integration into production

Because the grade is tuned for the ISO P group, these inserts are suitable for a range of unalloyed and alloyed Stahl grades encountered in most shops. When integrating the insert into existing tool systems, match feed and speed to the workpiece condition and machine rigidity; the Tiger·tec Silver coating supports increased cutting speeds where machining conditions allow. If process-specific cutting data or compatibility checks are needed, the technical team at Metav Werkzeuge can assist with tailored recommendations and cutting parameter suggestions to maximise productivity.

FAQ

What materials is this insert designed for?
The WCMT040204-E47 WPP20S insert is designed primarily for machining Stahl materials and conforms to the ISO P material group performance expectations.

How does the Tiger·tec Silver coating benefit production?
The Tiger·tec Silver coating reduces friction and thermal impact at the cutting edge, extending tool life and allowing for higher stable cutting parameters with the WPP20S grade.

What advantage does the Trigon 80° form provide in drilling and boring?
The trigon 80° form offers a stable cutting geometry that improves engagement and reduces deflection during drilling and boring, contributing to consistent hole quality.

Is the E47 chipbreaker suitable for interrupted cuts?
Yes, the E47 chipbreaker is engineered to control chip formation under the heat and chip-flow conditions typical when machining Stahl, and it performs well in interrupted cuts.
