ZDGT150408R-K85 WNN15 milling indexable insert, 15° clearance — Walter Tools

The ZDGT150408R-K85 WNN15 is a precision milling indexable insert designed for general milling tasks where consistent chip formation and robust edge retention are required

• Coated carbide grade WNN15 for broad material range
• 15° clearance angle for stable cutting
• 0.8 mm corner radius for precise edge control

High productivity through optimised grade and chip control

The coated carbide grade WNN15, combined with the K85 chipbreaker, delivers a balance of wear resistance and controlled chip formation that supports continuous production. The geometry promotes predictable cutting forces and reduced vibration, resulting in improved tool life and more repeatable process results. For operations where cycle time and process stability matter, this insert’s specification targets efficient material removal and consistent surface quality.

Geometry designed for accuracy and edge stability

A 15° clearance angle and a 0.8 mm corner radius contribute to a cutting edge that resists chipping while maintaining dimensional control. The insert’s inscribed circle of 15 mm and plate thickness of 4 mm provide a stable seating and heat distribution during milling cycles; the tolerance class G ensures consistent fitment in standard toolholders. These geometric choices reduce the risk of premature edge failure and support finer surface finishes when compared with more aggressive corner radii.

Flexible application scope with factory-grade coating

Classified as coated carbide within the Walter grade series (open series), the insert is intended for a broad range of workpiece materials — final suitability should be validated against the specific product matrix. The execution code T indicates the insert’s version within the series, and the ISO designation clarifies interchangeability with compatible tool systems. For production engineers and machinists seeking predictable performance in mixed-material batches, this insert provides a pragmatic baseline: reliable cutting behaviour with easy grade allocation.

FAQ

What materials can be machined with this insert?
The WNN15 grade is a coated carbide intended for a broad material range; specific suitability for particular alloys must be checked against the product matrix for the ZDGT150408R-K85 WNN15 insert.

How does the K85 chipbreaker affect milling performance?
The K85 chipbreaker promotes controlled chip formation and evacuation, supporting stable cutting forces and reduced risk of built-up edge for consistent milling cycles.

What does the 0.8 mm corner radius mean for surface finish?
A 0.8 mm corner radius balances edge strength and finish quality — it enhances edge stability while allowing improved surface integrity compared with larger radii in many milling tasks.

Is the insert compatible with standard toolholders?
The ISO designation and the inscribed circle of 15 mm indicate compatibility with matching toolholder systems; tolerance class G supports consistent seating and interchangeability.

How is the material or coating specified?
The insert is specified as coated carbide under the Walter grade WNN15; the exact coating and substrate details are catalogue-dependent and listed in the manufacturer documentation.
