• Walter open series for versatile insertion

Improved process reliability thanks to coated carbide and geometry

The combination of a coated carbide cutting grade and a dedicated chipbreaker provides a measurable improvement in tool life and reproducibility under comparable cutting conditions. The WNN15 grade denotes a coated hardmetal class that is optimised for general turning and drilling tasks; its layered surface treatment reduces abrasive wear and supports a stable cutting edge. Because the precise workpiece suitability depends on the product matrix, material compatibility should be verified prior to series use, preserving efficiency and avoiding unexpected downtime.

Predictable chip control reduces rework and machine stops

A precisely shaped 2R04‑G88 chipbreaker promotes short, controllable chips during drilling and counterboring, lowering the risk of entanglement and enabling uninterrupted production cycles. Controlled chips contribute directly to improved surface quality and reduced secondary operations, which in turn supports a leaner workflow and lower per-part labour input. The insert’s geometry also aids consistent coolant access and stable cutting temperatures, reinforcing process reliability across repetitive batches.

Easy integration into modular cutter systems and application planning

Designed for compatibility with standard indexable toolholders, the insert supports rapid seating and indexation, helping to maintain cycle-time efficiency during tool changes. Application planning is simplified by the clear designation and series information; the open Walter grade series allows flexible selection across similar operations. For precise feed and speed values and to confirm material suitability, consult the product matrix or contact Metav Werkzeuge for tailored recommendations to match the machining task.

FAQ

What materials is this insert suitable for?
Material suitability depends on the product matrix; the P4460-2R04-G88 WNN15 is a coated carbide grade intended for general drilling/counterboring tasks, so consult the technical matrix to confirm compatibility.

Can the insert be used in any standard indexable holder?
The insert is designed for modular cutter systems; compatibility should be checked against the holder geometry and clamping specifications before installation.

How does the 2R04‑G88 chipbreaker affect machining?
The 2R04‑G88 geometry promotes short, consistent chips for cleaner evacuation, which supports improved surface quality and lowers the likelihood of machine interruptions when using the insert.

Is the WNN15 grade suitable for high-speed operations?
WNN15 is a coated hardmetal grade offering wear resistance; confirmation of high-speed suitability requires reference to the product matrix and cutting-parameter guidance for the insert.

How is tool life optimised with this insert?
Optimised tool life is achieved through the coated carbide grade and the chipbreaker design, which together reduce abrasive wear and stabilise cutting forces during repetitive drilling and counterboring tasks.
