ONHU 0705AN AH725 indexable insert for milling — Tungaloy DoFeed

ONHU 0705AN AH725 is an octagonal indexable insert designed for high-feed milling, pocketing and face machining, supplied for system use with matching milling bodies and screws.

• High-feed milling capacity
• PVD-coated AH725 universal grade
• Octagonal insert for multiple indexing
• Cylindrical hole with 40°–60° countersink

Increase throughput with high-feed geometry

The DoFeed family is engineered for large material removal rates at small axial depths, translating directly into shorter cycle times and fewer tool changes. The octagonal geometry increases available indexing positions, which improves cutter utilisation and reduces cost per edge. Together with the 135° cutting angle, this shape supports stable cutting forces and predictable chip flow, making the insert particularly suited to high-feed milling and aggressive pocketing operations while maintaining surface quality.

Secure process reliability with AH725 and PVD coating

The AH725 grade combines a PVD-coated carbide substrate with a fracture-resistant microstructure, created for mixed-material environments and small-tool applications where process security is critical. The coating enhances wear resistance and adhesion under interrupted cuts; the substrate balances toughness and hardness to reduce edge chipping. This results in consistent tool life when machining steel and rostfreier Stahl, lowering rework rates and improving batch-to-batch reproducibility for production runs.

Precise clamping and versatile system compatibility

The insert’s cylindrical hole with double countersink (40°–60°) and 5.56 mm thickness ensure secure clamping in compatible DoFeed milling bodies, while the double-sided chipbreaker offers two usable cutting edges for efficient indexing. The combination of octagonal form, 0 mm corner radius and a 135° approach angle gives a balance of positive cutting action and robust edge strength. The insert is supplied as part of a system comprising the milling body, matching inserts and fastening screws, supporting straightforward integration into existing machining setups. The ONHU0705AN AH725 insert supports consistent performance across repeated cycles and simplifies tool inventory management.

FAQ

What types of milling is this insert best suited to?
The insert is tailored for high-feed milling, pocketing and face machining; the DoFeed geometry and AH725 grade support large material removal rates with stable cutting behaviour.

Is the insert compatible with standard DoFeed milling bodies?
Yes, the ONHU0705AN is designed as part of the DoFeed system and fits matching milling bodies when secured with the specified screws.

Which materials can be machined with this grade?
The AH725 grade is a universal, fracture-resistant option for machining steel and rostfreier Stahl, offering reliable performance where material changes occur.

How does the octagonal shape benefit production?
The octagonal form provides multiple indexing positions, extending the number of usable edges per insert and lowering tooling cost per part while maintaining cutting stability.

Does the insert require a specific clamping arrangement?
The cylindrical hole with double countersink (40°–60°) and 5.56 mm thickness are intended for secure clamping in compatible DoFeed holders to ensure reliable fixation under high-feed conditions.
