ONMU0705AN AH725 indexable insert for milling by Tungaloy — PVD-coated carbide, 135°

The ONMU0705AN AH725 is an octagonal indexable insert designed for Tungaloy milling systems, offering a universal, fracture-resistant grade suited to mixed-material jobs and applications demanding high process reliability.

• PVD-coated carbide AH725 universal grade
• Octagonal 07 form, 5.56 mm plate thickness
• Central hole with cylinder bore and countersink
• Double-sided chipbreaker for stable chip control

Consistent process security with a universal PVD grade

The PVD-coated AH725 grade provides a balance of wear resistance and toughness that is aimed at frequent tool changes between different steels. As a PVD-coated carbide, the coating reduces flank wear while the substrate maintains fracture resistance; this combination is particularly valuable where machining conditions or workpiece materials vary. The result is a predictable tool life and fewer unscheduled interruptions in production. The insert ONMU0705AN AH725 is specified for application in a wide range of milling tasks and is especially practical for smaller cutters or operations with tight demands on process reliability.

Optimised chip control and secure clamping for smoother cycles

An octagonal plate form coupled with a double-sided chipbreaker ensures controlled chip formation and evacuation, reducing the risk of built-up edge and improving surface finish. The insert’s central feature — a cylindrical bore with a double-sided countersink — enables precise seating and reliable torque transmission to the milling body, which helps to maintain stable cutting conditions. The 135° included angle contributes to mechanical strength at the cutting edge, supporting higher feed rates where the tool geometry and machine rigidity allow it.

System compatibility and straightforward integration into milling bodies

These indexable inserts are intended for use in complete Tungaloy milling systems; plattensitz, geometry and cutter body must match technically to ensure safe operation. The plate’s 5.56 mm thickness and size 07 designation are standardised dimensions that simplify selection and ordering for compatible tool families. Clamping is achieved via the specified hole and countersink geometry, which is designed to align with the appropriate clamping screw and, where required, a locating pad. Integration is therefore a matter of ensuring matching seat and cutter family rather than complex modification.

Application range and expected advantages in production

The insert supports a range of milling operations — planing, shoulder, slot, high-feed and contour milling — depending on the chosen cutter body. For workshops processing mixed batches, the AH725 grade gives a reliable compromise between wear resistance and toughness, suitable for steel and rostfreier Stahl. Benefits include extended runtime under variable conditions, improved surface quality in finishing passes, and reduced tool-change frequency when the system is properly matched and set up.

FAQ

What materials is this insert suitable for?
The ONMU0705AN AH725 insert is designed as a universal, fracture-resistant grade and is suitable for machining steel and rostfreier Stahl in a variety of milling operations.

How must the insert be mounted in the cutter body?
The insert requires a matching seat and geometry; the cylindrical hole with double-sided countersink ensures correct positioning and secure clamping when used in a compatible Tungaloy milling body.

Does the AH725 coating improve surface finish?
Yes, the PVD-coated AH725 grade reduces flank wear and supports consistent cutting behaviour, which contributes to improved surface finish under stable cutting conditions.

Which milling operations are common for this insert?
Typical applications include planing, shoulder, slot, high-feed and contour milling, depending on the associated cutter family and machine setup.

Is the insert reversible or double-sided?
The insert features a double-sided chipbreaker and is designed for indexing; exact usable edges depend on the insert orientation and system design specified by the cutter family.
