ONHU0705AN AH140 – Indexable insert for high-feed milling, PVD-coated carbide by Tungaloy

ONHU0705AN AH140 is a high-feed milling indexable insert designed for pocketing and face milling with small axial depths and high material removal per pass.

• High-feed family for large chip volumes
• PVD-coated AH140; wear and chip resistant
• Octagonal plate; 135° cutting angle
• Cylindrical hole with double-sided countersink

High-feed geometry that boosts productivity

The DoFeed series combines an aggressive rake geometry with a low axial engagement to enable high material removal rates while maintaining a small depth of cut. The resulting high-feed milling strategy reduces cycle time and improves utilisation of machine hours. Thanks to the PVD-coated AH140 grade on a carbide substrate, the cutting edge retains sharpness under fluctuating loads, which supports consistent cutting forces and fewer interruptions for tool changes. This paragraph explains how a specialised insert geometry leads directly to measurable productivity advantages.

Reliable edge control for demanding milling tasks

An octagonal plate form with a 135° cutting angle delivers an optimised contact zone and smoother entry into the cut, lowering the risk of edge chipping. The insert’s double-sided chipbreaker and the cylindrical hole with a double-sided countersink (40°–60°) enhance chip formation and evacuation, which reduces heat concentration and extends service life. For shops machining pockets and faces, this results in improved surface finish and reduced rework – a clear operational benefit derived from the technical design.

Robust grade and system compatibility for process security

The AH140 grade is a wear- and chip-resistant PVD-coated carbide developed for milling where a sharp cutting edge and process reliability are required together. Integrated into a modular system comprising a milling body, matching inserts and fixing screws, the solution ensures repeatable positioning and straightforward replacement. The plate’s 5.56 mm thickness and zero corner radius provide mechanical stability in interrupted cuts, making this insert suitable for frequent entry/exit operations common in pocket milling.

Clear specification for setup and selection

Specification details such as the octagonal form, the presence of a locating hole with countersink, the 5.56 mm thickness, and the intended milling application make it straightforward to match the insert to compatible cutters and workholding. Choosing the correct grade and chipbreaker reduces trial-and-error at setup and supports a more predictable machining process. The modular nature of the system simplifies inventory management and facilitates quick insert changes during shifts.

FAQ

What materials is this insert suitable for?
The AH140 grade and carbide substrate of the ONHU0705AN AH140 insert favour applications that demand wear resistance and edge stability; it is specified for general milling tasks where a sharp edge and process security are required.

How does the DoFeed geometry affect machining performance?
DoFeed geometry enables large chip volumes at small axial depths, which increases material removal rates while reducing cutting forces per pass, so cycle times are shortened and tool utilisation improves.

What is the significance of the octagonal shape and 135° angle?
The octagonal form provides multiple indexing positions and the 135° cutting angle reduces entry shock and distributes cutting loads, lowering the risk of edge chipping during pocketing and face milling.
