ONMU0507AN AH3225 Tungaloy indexable milling insert – octagonal 05 insert for milling applications

The ONMU0507AN AH3225 is an indexable milling insert designed for a wide range of milling tasks within compatible Tungaloy systems, offering a wear-resistant cutting edge and secure clamping for stable production results

• PVD-coated carbide AH3225 for process security
• Octagonal 05 insert with 135° cutting angle
• Cylindrical hole with double-sided countersink
• Double-sided chipbreaker; wear-resistant design

Consistent cutting performance under high demand

The PVD-coated carbide grade AH3225 combines a hard coating with a tough substrate to deliver wear-resistant behaviour and reliable edge integrity during milling. This composition supports sharp initial cutting edges and reduced flank wear, which in turn maintains dimensional accuracy over longer tool life. For production environments where repeatability matters, this insert promotes process security and reduces scrap by stabilising the cutting result, especially during operations that require a clean, consistent finish.

Secure seating and reliable clamping for steady machining

The octagonal shape and the central cylindrical hole with a double-sided countersink (40°–60°) create uniform seating and repeatable clamping forces in the cutter body. The 135° cutting angle and a 7.94 mm thickness provide mechanical stiffness, helping to resist deformation under cutting loads and enabling higher feed rates where the toolholder and machine rigidity permit. Matching insert seat and geometry with the tool body is essential; correct pairing ensures the clamping screw and substrate act together for safe, vibration-resistant operation.

Versatile for plan, shoulder, groove and contour milling

With a double-sided chipbreaker and an octagonal form offering multiple indexable edges, this grade adapts to planing, shoulder cuts, groove operations, high-feed and contour milling depending on the chosen tool family. The insert size 05 and its zero corner radius support applications that prioritise accurate profiles and narrow tolerances. The geometry and chip control make the component suitable for varying depths of cut and feed rates, giving shops a flexible solution across workpiece materials where a robust, sharp edge is required.

Fewer tool changes and stable throughput reduce production costs

Using an indexable insert with a wear-focused grade like AH3225 leads to longer edge life and fewer tool changes, which lowers downtime and labour associated with tool handling. The double-sided use increases the number of available cutting edges per insert, while the PVD layer helps prevent premature breakdown under continuous operation. For process planners and operators looking to optimise cycle time, the combination of geometry, coating and construction supports consistent part quality and predictable tool-change intervals.

FAQ

What materials is this insert intended for?
The ONMU0507AN AH3225 insert is a PVD-coated carbide grade engineered for general milling tasks and offers good wear resistance across a broad material range when paired with the appropriate cutter body.

How does the octagonal form benefit production?
An octagonal plate provides multiple indexable edges, allowing more cutting edges per insert and reducing the frequency of tool replacements during continuous production runs with the ONMU0507AN AH3225.

What clamping features ensure secure seating?
Secure seating is achieved by the central cylindrical hole and the double-sided countersink; together they promote repeatable clamping forces and stable positioning in compatible Tungaloy milling systems.

Is the insert suitable for high-feed milling?
Yes, the geometry and AH3225 wear properties support high-feed applications when used in an appropriate toolholder and cutting parameter setup.

How many usable cutting edges are available on this insert?
The double-sided, octagonal design offers multiple usable edges; the exact count depends on how the insert is indexed and the specific geometry of the mounted cutting edges.
