APMT 070308 AH140 – Indexable milling insert for Fräsen by Tungaloy

APMT 070308 AH140 is an indexable milling insert designed for use in Tungaloy milling systems; suitable for face, shoulder, slot, high-feed and contour milling where process reliability and a sharp cutting edge are required

• PVD-coated carbide grade AH140
• One-sided chipbreaker for controlled chips
• Corner radius 0.8 mm for repeatable geometry
• Cylindrical hole with single-side countersink

Process-secure cutting with long tool life

The PVD-coated carbide grade AH140 provides a balance of wear resistance and edge stability that supports uninterrupted production. Designed as a replaceable indexable insert for milling, the grade is formulated to resist flank wear and chipping under common milling loads. This results in fewer tool changes and more consistent cycle times, which is particularly valuable in batch production and continuous machining environments. The combination of coating technology and substrate hardness contributes directly to improved process reliability and predictable tool life.

Geometry engineered for consistent surface quality

A corner radius of 0.8 mm combined with a 3.18 mm plate thickness and an effective 11° clearance delivers reproducible part geometry and surface finish. The parallelogram insert form provides positive cutting engagement and stable seating in compatible cutter bodies, while the one-sided chipbreaker assists in controlled chip formation for typical milling operations. These geometric parameters help maintain tolerance adherence across repeated indexing and are particularly useful when a sharp cutting edge and predictable scallop heights are required.

System compatibility and secure clamping for efficient handling

The insert is supplied with a cylindrical hole and a single-sided countersink (40°–60°) that ensures reliable clamping and straightforward orientation in Tungaloy milling bodies. Because insert seat, geometry and cutter body must match technically, this indexable design simplifies replacement and inventory management when a family of compatible cutter bodies is used. The overall package supports quick changeovers, reduced downtimes and a rationalised tooling strategy for production shops seeking both economy and performance.

FAQ

What applications suit this insert best?
This indexable milling insert is intended for milling operations such as face, shoulder, slot, high-feed and contour milling; the APMT 070308 AH140 insert by Tungaloy offers process security and edge stability for those tasks.

Is the insert compatible with standard Tungaloy cutter bodies?
Yes, compatibility is ensured when the insert seat, geometry and cutter body are technically matched; the APMT 070308 AH140 is intended for use within Tungaloy milling systems and requires the corresponding cutter family.

How does the AH140 grade affect tool life?
The AH140 PVD-coated grade provides improved wear resistance and reduced chipping, which typically extends tool life and offers more consistent cutting performance compared with uncoated substrates.

What role does the chipbreaker play in performance?
The one-sided chipbreaker promotes controlled chip formation and evacuation, reducing the risk of clogging and helping to maintain stable cutting conditions during interrupted and continuous cuts.

Can this insert be used for high-feed milling?
Yes; the insert is suitable for high-feed operations depending on the assigned cutter family and the specific machining parameters employed.
