ADMT 17T308 AH140 indexable milling insert — Tungaloy (PVD-coated carbide, 0.8 mm radius)

The ADMT17T308 AH140 is an indexable milling insert designed for general milling operations where a sharp cutting edge and process reliability are required

• PVD-coated carbide AH140 for wear resistance
• Sharp edge with stable chip control
• Parallelogram shape, 85° cutting angle
• One-sided chipbreaker for predictable chips

Consistent cutting performance for productive milling

The insert delivers consistent performance thanks to its PVD-coated carbide AH140 grade, which combines wear resistance with fracture toughness. In practice, this means longer tool life and fewer interruptions for insert changes, resulting in improved machine uptime. The one-sided chipbreaker promotes controlled chip formation, reducing the risk of built-up edge and maintaining surface quality on the workpiece. For process planners, the combination of coating and substrate provides a reliable baseline for tool-life calculations and cutting-parameter selection.

Precision geometry that supports repeatable results

The parallelogram profile with an 85° cutting angle and 0.8 mm corner radius gives a balance between strength and edge sharpness. This geometry supports shoulder, slot and contour milling operations depending on the assigned cutter body, while the 15° clearance angle helps reduce rubbing and thermal load. For engineers aiming for repeatable tolerances, the robust form and defined edge radius offer a predictable cutting interface and consistent component finish throughout production batches.

Compatibility and system-level benefits

These inserts are intended for Tungaloy milling systems and must match the cutter seat, insert geometry and milling body technically. The modular system approach—milling body, insert, clamp screw and, where required, pad—allows quick index changes and minimal inventory complexity across families. Using matching components reduces assembly errors and simplifies reconditioning workflows, supporting lean manufacturing practices and faster changeover routines.

Practical advantages for shop-floor application

With a 3.97 mm plate thickness and a central hole featuring a cylindrical bore plus a single-side countersink (40°–60°), the insert is straightforward to clamp securely. The design supports high-feed and finishing passes as dictated by the chosen tool family, while the sharp edge makes it suitable for operations where surface quality and dimensional control are important. The robust grade is suitable for general steels and a broad range of materials where a durable, sharp edge is required.

FAQ

What applications is this insert suitable for?
The ADMT17T308 AH140 insert is suitable for a range of milling operations including plan, shoulder, slot, high-feed and contour milling, depending on the assigned milling-body family.

How does the AH140 grade benefit production?
AH140 is a PVD-coated carbide grade that offers wear resistance and reliable edge stability; the combination extends tool life and improves process security during milling.

Is this insert compatible with non-Tungaloy milling bodies?
The insert requires a matching seat, geometry and milling body; compatibility with non-Tungaloy bodies depends on exact seat and clamping specifications.

What does the 0.8 mm radius mean for cutting?
A 0.8 mm corner radius balances edge strength and sharpness, helping to achieve good surface finish while resisting chipping during interrupted cuts.

Does the insert require a specific clamp or screw?
The insert is part of a system including the milling body, clamp screw and possibly a pad; correct clamping hardware and torque are essential for safe, repeatable performance.
