ACMT 07T308 AH140 Wendeplatten - Tungaloy

Benefit from the combination of a PVD-coated AH140 grade and a precise 0.8 mm corner radius to increase process reliability and surface quality in milling operations; the insert is compatible with Tungaloy milling systems and can be ordered via Metav Werkzeuge or discussed with our technical consultants.

ACMT 07T308 AH140 – Tungaloy milling indexable insert for Fräsen, PVD-coated carbide, 0.8 mm radius

The ACMT07T308 AH140 is a PVD-coated cemented carbide indexable insert for Tungaloy milling systems, engineered for face, shoulder, slot, high-feed and contour milling where a sharp cutting edge and process security are required.

• PVD-coated AH140 for wear resistance
• 0.8 mm corner radius for precise profiling
• Parallelogram shape with 85° cutting angle
• Cylindrical hole with countersink 40°–60°

Consistent cutting and extended in-process life

The PVD-coated grade delivers reliable wear resistance and improved edge stability under interrupted cuts. The AH140 coating on a cemented carbide substrate provides a balance between toughness and hardness, reducing the risk of chipping during heavy engagement. This stability translates into more consistent workpiece finish and fewer unplanned tool changes, which supports smoother production cycles and predictable tool consumption. The insert’s single-sided chipbreaker promotes manageable chip formation, helping to maintain cut quality across a variety of milling tasks.

Secure mounting and precise geometry for repeatable results

A stable clamping interface and correct seating are essential for repeatable performance; the insert’s parallelogram shape and 85° cutting angle suit applications requiring good radial engagement and accurate shoulder preparation. The central cylindrical hole with a single-sided countersink (40°–60°) ensures reliable retention in compatible Tungaloy cutter bodies, while the 7° relief angle and 3.97 mm thickness contribute to strength at the cutting edge. The 0.8 mm corner radius offers a useful compromise between strength and profile detail, enabling precise profiling without sacrificing robustness.

Practical selection guidance for production use

Selection should focus on matching insert, cutter body and seating geometry to achieve the expected results; the insert is part of a modular milling system, so technical compatibility with the tool body is mandatory. Typical uses include planing, shoulder milling, slotting and high-feed operations, where the combination of a sharp edge and process security is required. Choosing the AH140 PVD variant supports longer operational windows and reduces the likelihood of edge breakout in mixed-material production. For system integration, verify seat geometry and clamping method to ensure the intended performance is realised.

FAQ

What materials is this insert suitable for?
The ACMT07T308 AH140 is specified as a versatile milling insert; the AH140 PVD grade provides wear and chipping resistance suitable for a broad range of common milling materials where a sharp cutting edge and process reliability are required.

How does the 0.8 mm corner radius affect the finish?
A 0.8 mm corner radius balances edge strength with detail in the profile; it supports better surface finish on shoulders and faces while offering resistance to edge breakdown during medium to heavy milling.

Is the insert compatible with all Tungaloy milling cutters?
Compatibility requires matching of the insert seat, geometry and clamping method; the ACMT07T308 is designed for Tungaloy milling systems, but the cutter body must accept the ACMT geometry and the central-hole configuration.

What role does the single-sided chipbreaker play?
The single-sided chipbreaker assists in controlling chip formation and evacuation for the intended milling modes, contributing to stable cutting and reduced risk of recutting chips on the workpiece.

Can this insert handle interrupted cuts and slotting operations?
The combination of PVD-coated AH140 and a robust cemented carbide substrate improves edge stability under interrupted cuts; the insert is suitable for slotting and similar operations when fitted in an appropriate cutter body.
