ONHU 0705AN AH120 octagonal milling insert for high-feed milling — Tungaloy DoFeed, PVD-coated

The ONHU0705AN AH120 is an octagonal indexable milling insert engineered for high-feed milling, pocketing and face machining where large volume removal at small axial depths is required.

• DoFeed high-feed geometry for large removal rates
• PVD-coated AH120 grade for wear resistance
• Octagonal 07 form, 5.56 mm thickness
• Cylindrical hole with 40°–60° countersink

High-feed geometry that raises productivity without added depth

The DoFeed series is built to increase throughput by combining a specialised high-feed geometry with a stable cutting edge. The insert’s design enables large time-material volumes with only small axial engagements, which reduces the load on the spindle while maintaining high material removal per tooth. Thanks to the PVD-coated AH120 grade on a carbide substrate, the edge life is extended under continual operation and offers reliable performance for pocketing and planing tasks. This results in fewer indexings and steady cycle times, making the solution particularly suited to production environments focused on efficiency.

Geometry optimised for consistent surface quality and chip control

The octagonal form and the 135° primary geometry create a combination of multiple usable cutting edges and favourable cutting forces. A zero corner radius and a 0° clearance angle contribute to a predictable cutting action and repeatable part tolerances. The insert is equipped with a double-sided chipbreaker and a cylindrical hole with double-sided countersink (40°–60°) to support secure clamping and consistent chip evacuation. Together, these features reduce vibration and help maintain surface finish across pockets and large-area milling, so fewer reworks are required.

System compatibility and material applications for practical use

Supplied as part of a system comprising the milling body, matching indexable inserts and fixing screws, this insert integrates easily into existing DoFeed tool holders. The 0705AN size and 5.56 mm thickness provide clear dimensional standards for tool setup and fixture planning. The AH120 grade is developed for wear- and breakage-resistant performance, suitable for a wide range of milling tasks where a sharp edge and process security are required. Use with appropriate cutting data for steel and similar materials to exploit the insert’s economy and productivity advantages.

FAQ

What machining tasks is this insert best suited to?
The ONHU0705AN AH120 indexable insert (Tungaloy, SKU 6861806-Tungaloy) is optimised for high-feed milling, pocketing and face-milling where high removal rates at low axial depths are required.

How many usable cutting edges does the octagonal form provide?
The octagonal shape offers multiple indexable edges; the exact number depends on the specific clamping and index strategy used with the DoFeed milling body.

Is the AH120 grade suitable for interrupted cuts?
The AH120 PVD-coated carbide grade is designed to be wear- and breakage-resistant, offering good process security under typical interrupted and continuous milling conditions.

What clamping detail ensures correct seating of this insert?
The insert has a cylindrical hole with a double-sided countersink (40°–60°), which supports secure clamping in the compatible DoFeed milling body and contributes to consistent positioning.

Are there recommended workpiece materials for this insert?
This insert is intended for general milling applications; when used with appropriate cutting data it is particularly effective on steels and similar materials where a sharp edge and process reliability are required.
