ADMT 130308 AH140 – Milling indexable insert, PVD-coated carbide by Tungaloy

The ADMT130308 AH140 is an indexable insert for milling operations, engineered for face, shoulder, slot, high-feed and contour milling when used with compatible Tungaloy milling bodies.

• PVD-coated carbide for wear resistance
• Sharp cutting edge with process stability
• Parallelogram shape with cylindrical hole
• 0.8 mm corner radius for precision

Reliable performance for productive milling

The combination of a PVD-coated carbide substrate and the AH140 grade delivers a balance of wear resistance and chipping toughness that suits continuous production environments. A consistently sharp cutting edge reduces vibration and helps maintain surface finish, while the grade's resistance to breakage supports higher process security. In practice this reduces unplanned tool changes and increases uptime, which translates into measurable productivity gains for milling operations where repeatable metal removal rates are essential. The emphasis is on stable machining rather than aggressive overcutting.

Precision geometry for repeatable results

The insert’s parallelogram form with a cylindrical hole and a one-sided countersink (40°–60°) provides secure and repeatable clamping in compatible tool bodies, ensuring accurate seating and consistent cutting geometry. The specified 0.8 mm radius and the 15° clearance angle contribute to controlled chip flow and predictable edge engagement, while the overall geometry, defined by an 85° main angle, supports versatile tool paths. These design choices simplify process set-up and help achieve consistent tolerances across batches without complex adjustments.

Integration and application guidance for reduced setup time

Designed as part of a system comprising a milling body, indexable insert, clamping screw and, where required, a backing pad, this insert requires a correct match of seat, geometry and body to perform as intended. Typical applications include planing, shoulder milling, slotting and high-feed passes, depending on the selected tool family. The single-sided chipbreaker improves evacuation for many common materials.

FAQ

What is the primary benefit of the AH140 grade?
The AH140 grade provides a wear- and fracture-resistant PVD-coated carbide that combines a sharp cutting edge with enhanced process security for stable milling.

Is the ADMT130308 compatible with all Tungaloy milling bodies?
Compatibility requires matching the insert seat, geometry and body; the ADMT130308 performs reliably when used with Tungaloy milling systems that accept this parallelogram insert form.

Which milling tasks suit this insert best?
The insert is intended for planing, shoulder, slot, high‑feed and contour milling, depending on the specific tool family and cutting parameters.

How does the 0.8 mm radius affect results?
A 0.8 mm corner radius balances edge strength and finish quality, reducing the risk of chipping while maintaining dimensional precision on machined features.

What does the hole and countersink design provide?
The cylindrical hole with a single‑side countersink (40°–60°) ensures a secure, repeatable clamp interface that stabilises the insert during higher cutting loads.
