ONMU 0705AN AH120 ONMU milling insert — PVD-coated carbide, double-sided chipbreaker by Tungaloy

The ONMU 0705AN AH120 is a PVD-coated carbide indexable insert designed for face, shoulder, slot, high-feed and contour milling within compatible Tungaloy milling systems.

• PVD-coated carbide grade AH120
• Double-sided chipbreaker for stable chips
• Octagonal form with zero corner radius
• Cylindrical hole with 40°–60° countersink

Enhanced productivity through wear-resistant cutting edges

The AH120 grade is a PVD-coated carbide developed for wear and chipping resistance, combining a sharp edge with process stability. This composition reduces flank wear and delays edge breakdown under interrupted cuts, which supports longer tool life and fewer indexings. In practice, the result is improved component throughput and a steadier surface finish, particularly in heavy-duty and high-feed milling operations where consistent cutting geometry is essential.

Geometry and clamping that secure repeatable results

The insert’s octagonal form and zero corner radius provide multiple active edges while maintaining a predictable cutting line; the 135° geometry contributes to edge strength and cutting behaviour. A plate thickness of 5.56 mm and size designation 07 ensure a robust seating, while the cylindrical hole with double-sided countersink (40°–60°) delivers reliable clamping and axial positioning. These features together reduce vibration and facilitate repeatable part tolerances when the insert is mounted in a correctly matched cutter body.

System compatibility and practical workshop guidance

This insert is intended for use in complete Tungaloy milling systems, where insert seat, geometry and cutter body must match technically for safe operation. The typical system consists of the milling body, the indexable insert, a clamping screw and, if required, a backing plate or support. Selection should be based on the tool family and the intended milling type (face, shoulder, slot, high-feed, contour). For best results, correlate the AH120 grade and the double-sided chipbreaker to the intended feed and depth parameters and confirm mechanical fitment before production runs.

FAQ

What benefits does the AH120 coating deliver?
The AH120 PVD-coated carbide provides enhanced wear resistance and improved resistance to edge chipping, making the insert suitable for interrupted cuts and conditions where a sharp cutting edge and process stability are required.

Which milling operations are suitable for this insert?
The insert is intended for face, shoulder, slot, high-feed and contour milling depending on the assigned tool family; match the ONMU 0705AN AH120 to the appropriate cutter body for each specific operation.

What must be checked before installation?
Ensure the insert seat, geometry and cutter body are technically compatible; confirm the clamping screw and any backing plate are specified for the system to achieve secure seating and repeatable results.

What are the key dimensions to note for tool setup?
Key dimensions include plate thickness 5.56 mm, insert size 07, included angle 135°, corner radius 0 and the cylindrical hole with 40°–60° countersink; reference the SKU 6861795-Tungaloy when ordering.

Is the chip control integrated in the insert design?
Yes, the insert features a double-sided chipbreaker designed to maintain stable chip formation across the specified milling operations.
