ZDGT150440R-K85 WNN15 indexable milling insert – 15° relief, K85 chipbreaker | Walter Tools

ZDGT150440R-K85 WNN15 is an indexable milling insert engineered for productive general milling where reliable chip control and predictable tool life are required

• Coated carbide grade WNN15 for broad materials
• K85 chipbreaker for consistent chip control
• 15° relief angle for stable cutting
• 4 corner radius for robust edge strength

Consistent chip control for higher throughput

The combination of the K85 chipbreaker and the WNN15 coating creates stable chip formation, which reduces interruptions from chip jamming and improves cycle times. The chip geometry is designed to break and evacuate chips predictably under normal milling parameters. For manufacturers seeking reduced downtime and steadier removal rates, this geometry translates into fewer operator interventions and a more continuous production flow. The insert’s cutting geometry supports smooth engagement and exit from interrupted cuts, helping to maintain surface finish and part tolerances.

Coating and substrate for reliable tool life

A coated carbide substrate provides the balance between edge stability and wear resistance needed for mixed-shop environments. The WNN15 grade is optimised as a versatile coated carbide solution; it aims to deliver a predictable wear pattern and resistance to abrasion across a range of workpiece materials. Combined with the 15° relief angle, the insert maintains a consistent cutting edge condition during milling, which in turn helps to reduce the frequency of index changes and maintain production consistency. This results in lower tool management overhead and more repeatable component quality.

Geometry and robustness for secure machining

The insert’s corner radius 4 and plate geometry increase edge strength and resistance to chipping in moderate interrupted cuts. The nominal plate size and thickness provide stable clamping in standard milling cutters, while the specified tolerance class supports interchangeability within the same tool family. When selecting cutting parameters, matching feed and speed to the K85 chip control characteristics will deliver the best compromise between metal removal rate and surface quality. For new applications, start with conservative feeds and increase until the desired removal rate and finish are achieved.

FAQ

What materials is this insert suitable for?
The ZDGT150440R-K85 WNN15 insert is supplied as a coated carbide grade and its WNN15 matrix is designed for broad material coverage; check the product matrix for exact workpiece compatibility.

How does the K85 chipbreaker affect performance?
The K85 chipbreaker provides consistent chip control and improved evacuation, reducing stoppages and supporting higher effective machining throughput with the Walter Tools insert.

What is the purpose of the 15° relief angle?
A 15° relief angle helps to maintain a stable cutting action and reduces rubbing at the flank, contributing to improved surface finish and longer usable edge life for this indexable insert.

Can the corner radius be changed for different applications?
This insert features a corner radius of 4; changes to radius are achieved by selecting an alternative insert geometry rather than modifying this specific item.

Is the ZDGT150440R-K85 WNN15 compatible with standard milling cutters?
The insert is intended for use in compatible indexable milling cutter systems that accept its designation; ensure correct seat and clamp specification when installing the insert.
