CCMT 09T302 AH725 indexable turning insert — PVD-coated carbide, rhombic CCMT by Tungaloy

CCMT 09T302 AH725 is an ISO-standard indexable turning insert designed for external and internal turning, offering a small 0.2 mm nose radius and an 80° approach angle for versatile finishing and light roughing operations.

• PVD-coated carbide grade AH725
• Robust single-sided chipbreaker geometry
• Rhombic CCMT form with 0.2 mm nose
• ISO compatibility and standard fixing

Reliable performance for mixed-material turning

The PVD-coated AH725 carbide grade delivers a balanced combination of wear resistance and toughness, making the insert particularly suited for machining Stahl and rostfreier Stahl in variable production environments. The rhombic CCMT form and 0.2 mm nose radius provide predictable contact conditions, which reduces vibration and helps maintain surface quality. This design is especially beneficial when handling frequent material changes or when toolholders are compact and rigidity is limited.

Improved process security and chip control

Built with a single-sided chipbreaker, the insert supports controlled chip formation across a range of cutting parameters, aiding chip evacuation and reducing the risk of built-up edge. The insert’s geometry, together with the PVD-coated surface, contributes to stable cutting forces and repeatable tool life, which can reduce downtime and achieve consistent component tolerances. Those seeking measurable process improvements will value the combination of edge stability and chip management.

Compatibility, clamping and mounting considerations

The insert conforms to ISO specifications for CCMT-type plates and requires a compatible external holder or boring bar; compatibility is determined by form, clearance, tolerance class, fastening method, size and thickness. The plate features a cylindrical hole with a single-sided countersink (40°–60°) and a plate thickness of 3.97 mm, which suits common ISO clamping systems. Checking holder geometry and clearance angles ensures optimal seating and repeatable clamping for serial production.

Small-radius finishing and tool-life balance

With an 80° approach angle and 7° clearance, the geometry favours fine surface results while maintaining enough robustness for light to moderate material removal. The compact nose radius is ideal for achieving tight profile detail and controlled cutting engagement. The universal characteristics of the grade make it an efficient choice when a single insert must cover both Stahl and rostfreier Stahl applications without frequent tool changes.

FAQ

What materials is this insert suitable for?
The CCMT 09T302 AH725 insert is specified for machining Stahl and rostfreier Stahl; the AH725 grade gives a universal balance of wear resistance and toughness for mixed-material environments.

Which holders are compatible with this insert?
Compatibility depends on holder form, free angle, tolerance class, fastening, size and thickness; the insert is ISO-standard CCMT and fits holders designed for CCMT 09 inserts with the corresponding clamping and countersink arrangement.

How does the chipbreaker affect machining?
The single-sided chipbreaker promotes predictable chip formation and evacuation, improving process security and reducing the likelihood of built-up edge during turning with moderate cutting parameters.

Is the insert suitable for finishing operations?
Yes — the 0.2 mm nose radius, 80° approach angle and 7° clearance make it well suited to fine finishing and light profile work while retaining edge robustness.

What are the advantages of the AH725 grade?
AH725 is a PVD-coated carbide grade that offers universal performance with good edge stability and wear resistance, especially where varied material batches and high process reliability are required.
