CCMT120412-E47 WPP20S — Drilling/Boring Indexable Insert, Rhombic 80° (Walter Tools)

The CCMT120412-E47 WPP20S is a coated carbide indexable insert optimised for steel machining, combining Tiger·tec Silver surface technology with a precise chipbreaker for stable chip control in production environments

• Tiger·tec Silver coating for robust edge life
• Grade WPP20S optimised for steel machining
• Rhombic 80° geometry for secure clamping
• 7° clearance angle with 1.2 mm corner radius

Faster cycles through a wear-resistant coating

The combination of Tiger·tec Silver surface treatment and the WPP20S coated carbide grade reduces flank wear and promotes a stable cutting edge under typical steel cutting temperatures. This delivers higher throughput because the insert maintains dimensional accuracy over more parts, which reduces changeover frequency and machine downtime. The coated surface also improves friction behaviour at the cutting zone, supporting consistent surface finish and more predictable tool life in serial production.

Predictable chip control and secure seating for reduced rework

The chipbreaker E47 paired with the Rhombic 80° form provides controlled chip formation and evacuation when machining steels in ISO group P. The combination of the 1.2 mm corner radius and 7° clearance angle stabilises the cutting edge and spreads cutting forces across a larger area, which reduces the risk of notch wear and edge chipping. As a result, the insert supports reliable process security and fewer interruptions for manual rework or part remeasurement.

Engineered geometry for repeatable precision and machine efficiency

The insert’s geometry and tolerance class M ensure repeatable seating and constant cutting conditions from one insert to the next. The rhombic configuration provides multiple indexable cutting edges, improving tool utilisation and lowering per-part tooling cost in high-volume runs. For shops seeking consistent performance when machining unalloyed and alloyed steels, this solution balances cutting-edge longevity with predictable metal‑removal rates, reducing scrap and improving overall plant productivity.

FAQ

What materials is this insert intended for?
This insert is specified for machining steels (ISO group P); the WPP20S grade and Tiger·tec Silver coating are optimised for unalloyed and alloyed steel applications.

How does the Tiger·tec Silver coating improve performance?
The Tiger·tec Silver coating reduces friction and wear at the cutting edge, which helps maintain edge stability and extends the interval between index changes.

What production benefits does the rhombic 80° form deliver?
The rhombic 80° geometry enables secure clamping and multiple indexable edges, improving tool utilisation and delivering repeatable cutting conditions.

Is this insert suitable for heavy interrupted cuts?
The combination of the 1.2 mm corner radius and the WPP20S grade increases robustness at the edge, making the insert a suitable choice for many interrupted cutting scenarios in steel, depending on specific cutting parameters.

Can the chipbreaker handle a range of chip thicknesses?
The E47 chipbreaker is designed to control chip formation across a typical range of steel cutting parameters, supporting stable chip flow and predictable evacuation.
