CPMW050208 GH330 indexable milling insert — Tungaloy

The CPMW050208 GH330 is a rhombic 05-format indexable insert for milling, designed for productive face, shoulder, slot and contour milling with a 0.8 mm corner radius and a secure clamping hole.

• GH330 grade for wear resistance
• Rhombic 05 form with 0.8 mm corner radius
• Cylindrical hole with 40°–60° countersink
• Carbide body for productive milling

Longer tool life through optimised grade and geometry

The combination of the GH330 cutting grade and a carbide substrate provides a balance of wear resistance and toughness that supports consistent tool life. The 0.8 mm corner radius reduces edge chipping under moderate to heavy feeds while maintaining cutting stability, which helps to reduce unscheduled tool changes and keeps machine downtime to a minimum. This leads to improved process economy and a more predictable production flow when using the insert in a compatible milling body.

Secure seating and predictable cutting behaviour

A cylindrical hole with a single-sided countersink (40°–60°) ensures reliable clamping and repeatable seating in the cutter body, contributing to vibration control and positional accuracy. The insert’s rhombic 05 shape combined with an 11° relief angle and an 80° included angle produces a cutting geometry suited to general-purpose milling tasks while allowing good access for shoulder and contour work. These geometric characteristics support consistent chip formation and surface finish when matched to the correct cutter and clamping hardware.

Versatility across standard milling tasks

The insert is intended for a range of milling operations — from face and shoulder milling to slot, high-feed and contour milling depending on the chosen tool family. With no chipbreaker fitted, the component is particularly suited to operations and cutting conditions where chip control is provided by the cutter body design or by process parameters. The design supports efficient material removal and reliable surface quality, making the insert a practical choice for production environments where versatility and throughput are priorities.

Compatibility notes and installation guidance

Correct function depends on matching the insert seat, geometry and cutter body; the insert thickness of 2.38 mm must be compatible with the chosen toolholder and clamping screw. As the insert is supplied without a chipbreaker, ensure cutting parameters and the chosen milling body provide the required chip control for the workpiece material. For application-specific setup and parameter recommendations, the Metav Werkzeuge team can advise on cutter‑to‑insert matching and feed/speed optimisation to achieve stable, repeatable results.

FAQ

What materials is this insert suitable for?
The CPMW050208 GH330 insert is a carbide cutting grade intended for general milling tasks; the GH330 grade offers a balance of wear resistance and toughness suitable for a wide range of steels and general workshop applications.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius improves edge strength and reduces chipping risk under heavier feeds, which helps to extend tool life and maintain surface quality when using the insert in appropriate milling conditions.

Is a chipbreaker included and how does that change cutting strategy?
This insert is supplied without a chipbreaker; machining strategies should rely on cutter body chip control or adjusted cutting parameters to ensure safe and effective chip evacuation.

Which cutter bodies are compatible with this insert?
Compatibility requires that the insert seat, geometry and cutter body are technically matched; the insert’s cylindrical hole and countersink require a clamping system that accepts the CPMW050208 form and 2.38 mm thickness.

What clamping and seating features assist repeatability?
The cylindrical hole with a single-sided countersink (40°–60°) ensures secure clamping and consistent seating, improving repeatable positioning and helping to control vibration in production runs.
