CCMT060204 AH725 CCMT turning insert by Tungaloy — PVD-coated carbide, one-sided chipbreaker

CCMT060204 AH725 is a rhombic ISO turning insert designed for general-purpose external and internal turning where process safety and chip control are priorities.

PVD-coated carbide AH725 grade
Universal for Stahl and rostfreier Stahl
Rhombic 06 form with 80° lead angle
0.4 mm nose radius and 7° relief

Consistent performance across mixed batches

The PVD-coated AH725 carbide offers a balance of wear resistance and notch toughness that is suited to variable production runs. With a one-sided chipbreaker and a modest 0.4 mm nose radius, the insert stabilises chip formation and reduces the risk of edge chipping when machining different alloys. For shops facing changing components, this combination reduces tool changes and helps maintain cycle-time consistency. The grade is engineered for turning operations where repeatable surface quality and reliable cutting-edge behaviour are required.

Designed for secured seating and ISO compatibility

Compatibility with holders is determined by form, relief angle, tolerance class, fastening method, size and thickness; the rhombic 06 format and 80° approach angle ensure broad fitment with common ISO turning toolholders. The insert features a cylindrical hole with a one-sided countersink (40°–60°) which supports stable clamping and repeatable positioning. Specifying a matching seat and torque for screws results in consistent clamping force and reduces the likelihood of vibration-related wear, translating into longer effective tool life and more predictable process windows.

Practical advantages for productivity and process security

The universal nature of the AH725 grade means fewer tool variants are necessary for batches comprising both Stahl and rostfreier Stahl, simplifying inventory and tool management. The PVD-coated carbide layer improves thermal resistance at elevated cutting speeds, while the substrate provides mechanical strength. These characteristics yield a favourable cost-in-use ratio by extending cutting edge life and preserving surface finish quality under typical turning conditions.

Handling, inspection and recommended use

The insert’s modest thickness and standard ISO geometry make it straightforward to inspect and replace during scheduled tool checks. The rhombic shape and one-sided chipbreaker favour stable chip flow in conventional turning setups; selecting the appropriate holder and matching the insert’s relief and tolerance class is critical for optimal results. For high-process-stability requirements, pairing this insert with a rigid toolpost and proper coolant strategy will further enhance repeatability and surface integrity.

FAQ

Is this insert suitable for turning rostfreier Stahl?
Yes. The CCMT060204 AH725 insert is specified for machining Stahl and rostfreier Stahl and provides reliable chip control and wear resistance on both material classes.

Which holders are compatible with this insert geometry?
Compatibility follows ISO norms for rhombic inserts; select an ISO turning holder designed for CCMT 06 format that matches the insert thickness, hole style and clamping method.

What does the AH725 grade offer compared with standard grades?
The AH725 grade combines a PVD-coated surface with a substrate tuned for resistance to edge breakage, delivering stable performance across varying workpiece materials and small-tool applications.

Can the 0.4 mm nose radius deliver good surface finish on finishing passes?
A 0.4 mm nose radius balances strength and finish; it is suitable for semi-finish to finish operations where a compromise between surface quality and edge robustness is required.

How does the chipbreaker affect machining?
The one-sided chipbreaker promotes controlled chip formation in turning tasks, reducing the risk of long, entangling chips and improving machining stability under varying depths of cut.
