ACMT 060308 AH140 Wendeplatten - Tungaloy

Take advantage of a PVD-coated, wear- and chipping‑resistant carbide grade together with a controlled chipformer and secure clamping geometry for steady milling performance. The combination of a 0.8 mm corner radius and a parallelogram form ensures reliable edge life and process stability; order the ACMT060308 AH140 insert directly via Metav Werkzeuge or consult our specialists for application matching.

ACMT060308 AH140 indexable insert for milling by Tungaloy — PVD-coated, one-sided chipbreaker

The ACMT060308 AH140 indexable insert is intended for milling applications where a sharp cutting edge and process security are required; compatible units must match insert seat, geometry and milling body.

• PVD-coated carbide for high wear resistance
• One-sided chipbreaker for controlled chips
• Parallelogram form with 0.8 mm radius
• Cylindrical hole with 40°–60° countersink

Higher throughput from a wear-resistant coating

The insert uses a PVD-coated carbide grade (AH140) developed for milling tasks that demand both a sharp cutting edge and consistent tool life. The thin, hard coating reduces abrasive wear and helps to maintain edge geometry over longer cycles, which translates into fewer indexings and less machine downtime. For production environments the result is measurable: more finished parts per tool and improved process repeatability. The coating technology is explained here to aid selection: physical vapour deposition (PVD) applies a hard film to the substrate to resist abrasion while preserving toughness at the cutting edge.

Secure seating and geometry that reduces chatter

A stable clamping interface and the correct insert geometry are decisive for surface finish and tool life. This indexable plate features a parallelogram form and an 85° approach angle, together with a 7° clearance angle, which balance radial engagement and tool strength during face, shoulder and contour milling. The plate thickness of 3.18 mm and the defined seat geometry require the milling body and clamping screw to be matched precisely; correct assembly prevents micro‑movement and reduces the risk of edge breakouts. In practice, matching the insert to the cutter body is a straightforward way to increase process reliability and maintain consistent part quality.

Consistent chip control and versatile milling applications

Chip evacuation and edge protection are supported by a one-sided chipbreaker and a cylindrical hole with a 40°–60° countersink, enabling secure clamping and directed chip flow under a range of cutting conditions. The 0.8 mm corner radius increases edge robustness for medium to heavy engagement passes while still allowing acceptable corner definition. Typical uses include face milling, shoulder milling, slotting and contouring within the respective milling family; the insert is supplied as part of a system comprising the milling body, the indexable insert, a clamping screw and, where required, an underlay. Where process security and repeatable edge performance are priorities, this solution offers a pragmatic balance between productivity and tool life.

FAQ

What milling operations are suitable for this insert?
The ACMT060308 AH140 indexable insert is suitable for face milling, shoulder milling, slotting, high‑feed and contour milling within the appropriate Tungaloy milling system.

Which cutting conditions favour the AH140 grade?
AH140 is a wear‑ and chipping‑resistant PVD‑coated grade designed for applications where a sharp cutting edge and process security are required; it performs well under steady cutting with controlled chip evacuation.

How important is matching the insert to the milling body?
Very important — the insert seat, geometry and milling body must be technically compatible to ensure correct clamping and to avoid instability or premature edge failure when using the ACMT060308 AH140.

What are the key geometrical parameters to check before fitting?
Check thickness (3.18 mm), 0.8 mm corner radius, 7° clearance angle, 85° approach angle, plate form (parallelogram) and hole style (cylindrical with 40°–60° countersink).

What chip control features are integrated?
Chip control is provided by a one‑sided chipbreaker and the combined cylindrical hole with a one‑sided countersink, which support secure clamping and directed chip flow.
