ONMU 0705AN AH140 indexable insert for milling — Tungaloy

ONMU0705AN AH140 is an octagonal, PVD-coated indexable insert designed for Tungaloy milling systems, suitable for face, shoulder, slot and high-feed milling where a sharp cutting edge and process security are required.

• Octagonal form with 135° edge angle
• PVD-coated carbide grade AH140
• Double-sided chipbreaker for stable chips
• Cylindrical hole with countersink (40°–60°)

Consistent productivity for varied milling tasks

The octagonal geometry and the 135° edge angle provide stable cutting conditions across a range of operations, from face milling to high-feed and contour work. The combination of a robust shape and a PVD-coated carbide grade creates a balance between edge strength and wear resistance, improving tool life and reducing downtime. Integration into existing tool bodies is straightforward when the insert seat and geometry match the holder family, ensuring predictable machining results and shorter setup times.

Precision geometry that improves process security

An insert thickness of 5.56 mm and an eight-sided design produce uniform clamping and repeatable positioning in the tool body; this reduces vibration and helps maintain dimensional accuracy. The double-sided chipbreaker supports controlled chip formation, which in turn protects the cutting edge and the workpiece surface. For users who require reproducible component quality, the engineered form of this insert underpins stable cutting forces and a lower risk of unexpected tool failure.

Coating and grade explained for practical benefits

The AH140 grade is a PVD-coated carbide specifically formulated to be wear- and chipping-resistant in milling applications that demand a sharp edge and high process stability. A PVD layer increases resistance to abrasive wear while preserving edge sharpness; in simple terms, the coating extends productive life and sustains cutting performance at elevated speeds. Where process reliability is critical, the coating-grade pairing reduces the frequency of index changes and supports higher overall throughput.

Design details that aid handling and compatibility

The insert includes a cylindrical hole with a double-sided countersink (40°–60°) to fit the defined clamping screw and seat geometry used in compatible milling bodies. The corner radius is 0, enabling true sharp-edge cutting where required, especially in finishing or precise contour work. As an indexable component, the insert is economical: multiple cutting edges are available per index and replacement is rapid, lowering machine idle time and contributing to efficient production planning.

FAQ

What machining tasks is this insert designed for?
The ONMU0705AN AH140 indexable insert is intended for milling tasks such as face, shoulder, slot, high-feed and contour milling when used in compatible Tungaloy milling systems.

Which materials suit this grade best?
The AH140 PVD-coated carbide grade is optimised for applications requiring a sharp cutting edge and process security; it performs well where wear and chipping resistance are priorities.

How is the insert fixed to the milling body?
The insert has a cylindrical hole with a double-sided countersink (40°–60°) designed to fit the corresponding clamping screw and seat geometry of the matched milling body.

Can the insert be used for finishing passes?
Yes; the zero corner radius and sharp edge characteristic of this insert make it suitable for finishing and precise contour work when the correct cutting conditions are applied.

What should be checked before installing the insert?
Ensure the insert seat, geometry and the milling body are technically compatible; correct seating guarantees repeatable clamping, stable cutting and the intended process security with the ONMU0705AN AH140 insert.
