APMT 120408 AH140 – APMT milling insert for milling (PVD carbide, 0.8 mm radius) by Tungaloy

The APMT120408 AH140 is an indexable milling insert developed for versatile milling operations within Tungaloy milling systems, providing a wear-resistant cutting edge where process security and sharp geometry are essential.

• PVD-coated carbide AH140 for wear resistance
• 0.8 mm corner radius for precise edge control
• Parallelogram form for versatile cutter fit
• Countersunk hole for secure clamping

Stable cutting performance for predictable production

The combination of PVD coating and a wear-resistant carbide substrate delivers a consistently sharp cutting edge that preserves dimensional accuracy over extended runs. This translates into fewer tool changes and reduced machine downtime, which is especially valuable in high-volume milling. The AH140 grade is designed to balance edge stability with controlled wear, helping to maintain surface quality and minimise rework in serial production.

Geometry that simplifies setup and improves repeatability

The insert’s parallelogram form and central hole with a one-sided countersink provide secure location and clamping within compatible milling bodies. The 0.8 mm corner radius and an 85° approach angle support controlled chip formation and stable contact under varying cutting forces. These geometric attributes reduce vibration and contribute to repeatable seating, shortening setup times and improving process reliability for face, shoulder, slot and contour milling operations.

Process security and broad application within milling systems

This indexable plate is part of a system: the cutting body, the insert, the clamping screw and, where applicable, a shim must match technically for optimum performance. The AH140-coated insert is suitable when a sharp cutting edge and process security are required together, offering robust behaviour against chipping and wear. Its single-sided chipbreaker design aids controlled chip evacuation, making the insert a pragmatic choice for mixed-production environments seeking consistent results and fewer interruptions.

FAQ

What milling tasks is this insert intended for?
The AH140-coated APMT120408 is intended for face, shoulder, slot, high-feed and contour milling depending on the selected tool family and compatible milling body.

Which cutting performance advantages does the AH140 grade provide?
AH140 provides a PVD-coated carbide surface that improves wear resistance and edge stability, helping to maintain surface finish and reduce interruptions during prolonged milling.

How does the insert secure to the cutter body?
Secure clamping is achieved via the central cylindrical hole and one-sided countersink; this seating design ensures repeatable location and reliable clamping in compatible bodies.

Can this insert be used across different milling systems?
The insert will perform when the insert seat, geometry and cutter body are technically matched; confirm compatibility of the seat and clamping method before fitting.

What role does the corner radius play in cutting?
The 0.8 mm corner radius supports precise edge control and helps distribute cutting forces, improving surface quality while reducing the risk of chipping under intermittent or interrupted cuts.
