ONHU0705AN AH725 indexable insert — DoFeed high-feed milling, octagonal 07, Tungaloy

The ONHU0705AN AH725 indexable insert is a DoFeed-series component developed for high-feed milling, pocketing and face operations where large time-volume removal is required at small axial depths.

• High-feed DoFeed design for large material removal
• PVD-coated AH725 carbide for process security
• Octagonal 07 format with 135° approach angle
• Cylindrical hole with double countersink 40°–60°

Increase throughput with high-feed DoFeed geometry

The DoFeed family is designed to raise throughput by enabling large time-volume removal with low axial engagement. The octagonal 07 format combined with a 135° approach angle reduces cutting forces per edge, allowing higher feed rates while keeping tool projection and vibration low. With the PVD-coated AH725 carbide, this insert maintains edge integrity under fluctuating cutting conditions, delivering measurable reductions in cycle time without compromising component quality. The result is a clear productivity advantage in repetitive milling tasks.

Secure clamping and consistent chip control for stable machining

A cylindrical hole with double-sided countersink (40°–60°) provides confident mechanical locating and secure clamping in compatible milling bodies, while the double-sided chipbreaker geometry supports controlled chip formation across a range of feeds. These design elements combine to reduce chatter, stabilise the cut and help achieve repeatable surface finishes. For workshop managers aiming to reduce rework and tool-change frequency, the combination of form-fit clamping and optimised chip evacuation is a practical step towards more reliable process outcomes.

Wide material coverage and straightforward system integration

The AH725 PVD coating and the carbide substrate make this insert suitable for machining both steel and stainless steels, beneficial where frequent workpiece material changes occur. The DoFeed system comprises a milling body, matching indexable inserts and fixing screws, which keeps tool inventory compact and toolset-up time low. For applications requiring efficient pocketing or face milling with smaller cutters, the insert’s geometry supports straightforward integration into existing milling heads and reduces the need for specialised tooling.

Robust geometry and precise dimensions for predictable results

Key dimensions such as the plate thickness of 5.56 mm, the 07 size and a nominal corner radius of 0 deliver a profile that balances edge strength and cutting accessibility. The 135° angle contributes to a reduced radial cutting component and improved insert life in interrupted cuts. These numeric specifications provide a verifiable basis for process planning: they can be used directly in machining simulations and tool lists to ensure compatibility and to define cutting parameters with confidence.

FAQ

What cutting tasks is this insert best suited for?
The ONHU0705AN AH725 insert is optimised for high-feed milling, including pocketing and face milling where large time-volume removal is required at shallow axial engagement.

Which materials can be machined with this grade?
The AH725 PVD-coated carbide formulation is intended for use on steel and stainless steels, making the insert a versatile choice for mixed-material batches.

How does the octagonal shape affect performance?
An octagonal plate offers multiple indexing positions and good edge strength; coupled with the 135° approach angle, it reduces radial cutting forces and supports higher feed rates.

Is the insert compatible with standard DoFeed milling bodies?
Yes, the insert is part of the DoFeed system architecture and is intended to be used with compatible milling bodies, matching screws and clamping arrangements.

What role does the double-sided chipbreaker play?
The double-sided chipbreaker promotes consistent chip formation across a range of feed rates, improving chip evacuation and reducing the risk of built-up edge or unstable cutting conditions.
