ADMT 17T308 AH120 Tungaloy indexable insert for milling — PVD-coated carbide, 85° approach angle

An ADMT17T308 AH120 indexable insert engineered for process-secure milling in compatible Tungaloy tool systems, suitable for plan, shoulder, slot, high-feed and contour operations.

• PVD-coated carbide AH120
• 85° approach angle for stable cuts
• Parallelogram shape, 17 mm size
• Cylindrical hole with 40°–60° countersink

Consistent cutting performance that extends tool life

The combination of a PVD-coated surface and the AH120 grade provides improved wear resistance and a sharp cutting edge, which translates into longer service intervals and fewer unplanned tool changes. As a carbide insert with a reinforced cutting geometry, it reduces flank and crater wear under standard milling conditions and supports steady machining parameters. This results in a better cost-per-part ratio and a more predictable production flow for batch and continuous operations.

Secure seating and clamping for reliable process security

Designed as a parallelogram-shaped insert with a central hole and a one-sided countersink, the geometry ensures accurate locating and repeatable clamping in the matching milling body. The 85° approach angle and 3.97 mm plate thickness combine to deliver robust engagement with the workpiece while the 0.8 mm corner radius balances edge strength with form accuracy. Correct seat geometry and a compatible tool body are essential for the intended performance; the system comprises the milling body, the insert, the clamping screw and, where applicable, a backing pad.

Broad milling applications with controlled chip flow

The grade and single-side chipbreaker make this insert versatile across typical milling tasks — planing, shoulder cutting, grooving, high-feed and contouring — depending on the assigned tool family. The one-sided chip control offers improved evacuation in many operations and reduces the risk of re-cutting. Where a sharp edge and process reliability are demanded simultaneously, the AH120 composition helps maintain a consistent cut edge and surface finish, supporting shorter cycle times and stable dimensional results.

Practical advantages for production environments

Using indexable inserts reduces downtime and simplifies maintenance: worn cutting edges are replaced quickly without refitting a complete tool. The insert’s parallelogram format and central hole with a single-side countersink (40°–60°) facilitate easy orientation and secure clamping, while the PVD-coated surface aids thermal stability at elevated cutting speeds. The system approach—milling body, insert, clamping screw and backing—ensures a compact assembly strategy that supports efficient tool inventory management and predictable process outcomes.

FAQ

Is this insert compatible with non-Tungaloy milling bodies? The insert is designed for Tungaloy milling systems; the seat geometry, insert form and milling body must be technically compatible to ensure correct clamping and performance.

Which materials is this AH120 grade best suited to machine? The AH120 PVD-coated carbide grade was developed for wear- and chipping-resistant milling where a sharp cutting edge and process security are required; it is suitable for a wide range of common milling tasks.

How is the insert fixed into the tool body? Fixing is achieved via the central hole and clamping screw within the matching seat; the cylindrical hole with a single-side countersink (40°–60°) ensures secure location and repeatable seating.

What is the significance of the 0.8 mm corner radius? A 0.8 mm corner radius provides a compromise between edge strength and the ability to produce accurate contours and features, improving resistance to edge chipping while maintaining form accuracy.

Can the insert geometry be used for high-feed milling? Depending on the assigned tool family and body, the insert can be applied to high-feed operations; consult the tool body manufacturer data and recommended cutting parameters for confirmation.
