• K85 chipbreaker for controlled chip formation
• Series: Walter Schneidstoffsorte – Serie offen

Controlled chip formation for process stability

The insert is engineered for consistent chip control, thanks to the integrated K85 chipbreaker and the coated-carbide WNN15 grade. For milling processes where predictable chips reduce downtime and improve surface quality, the chipbreaker geometry separates and evacuates material efficiently, lowering the risk of built-up edge and tool jamming. In practise, this means fewer interruptions in production and a steadier cycle time when compared with unguided chip profiles.

Precision geometry that supports repeatable tool life

A defined 15° relief angle combined with the specified cutting-edge geometry contributes to extended tool life and repeatable cutting behaviour. The relief angle reduces friction on the flank face during cutting, which helps to maintain the cutting edge and stabilise cutting forces. For operators monitoring tooling costs and machine uptime, this geometry helps to balance wear and performance across batches of identical inserts, enabling predictable reconditioning or replacement intervals.

Material compatibility and application guidance

The insert is supplied in the Walter WNN15 coated-carbide grade; users should verify the exact material suitability against the product matrix for specific workpiece materials. Coated carbide typically performs well across a broad range of steels and cast alloys when matched to appropriate cutting data. For applications requiring improved surface finish or where chip control is critical, the combination of the WNN15 coating characteristics and K85 chipbreaker supports finishing and semi-finishing operations under stable machining parameters.

Handling, indexing and practical benefits on the shop floor

As an indexable insert, the part facilitates quick edge changes without the need to replace an entire cutter body, reducing setup time and waste. The defined geometry and series designation support simple tool assembly and inventory management in toolrooms that standardise on Walter Tools inserts. For maintenance planning, the predictable wear pattern simplifies decisions on regrinding, indexing or replacement, aiding both production planning and cost accounting.

FAQ

What machining tasks is this insert best suited for?
The ZDGT200550R-K85 WNN15 insert is designed for milling operations where controlled chip formation and reliable edge life are required; the K85 chipbreaker and WNN15 grade support finishing and semi-finishing tasks.

How does the 15° relief angle affect performance?
A 15° relief angle reduces flank contact and friction during cutting, which improves tool stability and contributes to predictable wear behaviour for the ZDGT200550R-K85 WNN15 insert.

Is WNN15 suitable for hardened steels?
WNN15 is a coated-carbide grade; material suitability depends on the specific workpiece and cutting data. It is recommended to verify compatibility using the product matrix or to consult Metav Werkzeuge for application-specific advice.

Can the insert be indexed to multiple edges?
Yes, the indexable design allows multiple edge positions, enabling efficient edge rotation to extend service life before replacement.

What maintenance or inspection routines are advised?
Regular monitoring of edge wear and chip form is advised; when chip control degrades or surface finish falls below tolerance, reindexing or replacement of the ZDGT200550R-K85 WNN15 insert should be performed.
