ONMU 0705AN AH3135 (Tungaloy) — Octagonal indexable insert for milling, PVD-coated carbide, with central hole

ONMU0705AN AH3135 is an octagonal indexable insert designed for milling applications where a precise cutting edge and process stability are required

• PVD-coated carbide grade AH3135
• Octagonal insert with 135° cutting angle
• Double-sided chipbreaker for stable chips
• Central hole with countersink for secure clamping

Consistent chip control and productivity for general milling

This octagonal, PVD-coated indexable insert is engineered to support a range of milling methods, from face and shoulder to high-feed and contour milling, depending on the chosen holder family. The AH3135 grade is optimised for resistance against wear and chipping, which helps maintain a sharp cutting edge over extended cycles. By combining a hard, wear-resistant surface with a geometry tuned for chip formation, the insert reduces unplanned tool changes and promotes a steady production rhythm. The design supports predictable performance across mixed material batches, contributing to measurable improvements in throughput and process efficiency.

Secure clamping and repeatable positioning for reliable machining

The insert features a central hole with a cylindrical bore and a double-sided countersink (40°–60°), enabling firm seating and repeatable location in compatible milling bodies. This clamping arrangement minimises micro-movement under load and supports consistent part quality, even at elevated feed rates. The 135° principal cutting angle distributes cutting forces over multiple edges, lowering stress on an individual corner and extending the usable life of each indexable edge. As a result, cycle-to-cycle repeatability is improved and downtime associated with edge failure is reduced.

Material compatibility and easy process integration

Manufactured from carbide and finished with a PVD coating, this insert suits a broad material spectrum where a robust, crack-resistant grade is needed. The double-sided chipbreaker enhances chip control across varying cutting conditions, reducing the likelihood of built-up edge and improving surface finish. When integrating into an existing tool family, ensure that the insert seat, geometry and clamping method of the milling body are technically compatible; matching those parameters preserves the engineered benefits of the insert and prevents uneven wear or instability during cutting.

Practical recommendations for selection and tool management

Choose this indexable insert where a combination of a sharp, wear-resistant edge and process security are priorities—typical use cases include finishing and medium-depth roughing where edge integrity and consistent chip evacuation matter. Inventory management benefits from the octagonal form: with multiple usable edges per insert, tooling costs per machined part are reduced. For cutting data and optimal feeds and speeds, reference the holder family specifications and, if required, contact Metav Werkzeuge for application-specific recommendations and verification of seating compatibility.

FAQ

Is this insert compatible with all Tungaloy milling bodies?
Compatibility depends on matching the insert seat, geometry and clamping method of the milling body; the ONMU0705AN AH3135 insert requires a holder that accepts an octagonal insert with a central, countersunk hole and the specified seat geometry.

What advantages does the AH3135 grade provide in milling?
The AH3135 grade offers a PVD-coated carbide combination that enhances wear resistance and reduces chipping, resulting in a sharper edge for longer and improved process security during milling.

Which milling operations are suitable for this insert?
The insert is intended for face, shoulder, slot, high-feed and contour milling depending on the selected holder family; it performs well where a robust edge and reliable chip control are required.

How does the 135° cutting angle affect performance?
A 135° principal cutting angle spreads cutting forces across more of the edge, lowering local stress and improving edge life, which benefits stability and surface finish in many milling applications.

Can the insert be indexed multiple times?
Yes, the octagonal design provides multiple usable edges per insert; careful handling and correct seating extend the number of effective indexes and improve cost-efficiency.
