DCMT070204 AH6225 indexable insert for turning by Tungaloy — rhombic 07, 7° relief

DCMT070204 AH6225 is an ISO-format indexable insert engineered for external and internal turning of stainless steels, offering a balanced mix of sharp cutting action and edge stability for medium machining conditions

• ISO rhombic insert, size 07
• PVD-coated carbide grade AH6225
• Single-sided chipbreaker for stable chips
• Compatible with standard DCMT holders, with hole

Consistent edge life and reliable cut quality for stainless steels

The PVD-coated carbide grade AH6225 is formulated as a universal solution for stainless steels, combining a sharp cutting geometry with enough edge support to resist premature wear. This balance reduces the risk of workpiece surface damage while maintaining productivity during medium-duty operations. The result is repeatable surface finish and predictable tool-change intervals, which supports planning and reduces downtime in batch production. The combination of coating and substrate improves heat resistance and adhesion, extending service life under variable cutting conditions.

Clear compatibility and secure mounting reduce setup time

Compatibility to a toolholder is defined by form, relief, tolerance class, clamping method, size and thickness; integration with existing DCMT-style holders is straightforward when these parameters match. The rhombic plate form with a 7° relief and a central hole with a single-sided countersink (40°–60°) allows positive locating and secure clamping in standard carriers. The presence of a countersunk hole ensures correct seat positioning and repeatable datum reference, simplifying calibration and toolpath verification in the workshop.

Controlled chip formation and predictable cutting behaviour

The single-sided chipbreaker and a 0.4 mm corner radius deliver controlled chip segmentation and a robust cutting edge for turnings where intermittent engagement or light finishing passes occur. Plate thickness of 2.38 mm contributes to insert rigidity, reducing vibration and improving dimensional stability. For applications that require switching between facing and external turning, the insert’s geometry and ISO conformity enable versatile use while maintaining consistent chip control and surface quality. Selection of chipbreaker and grade should be matched to material, machining strategy and machine stability for optimal results.

FAQ

What materials is this insert optimised for?
The DCMT070204 AH6225 insert is optimised for stainless steels; the AH6225 PVD-coated carbide grade is tuned for sharp cutting and stable edge life when machining such materials.

How does the hole and countersink affect mounting?
The insert’s central hole with a single-sided countersink (40°–60°) ensures secure and repeatable seating in DCMT-compatible holders, improving positional accuracy and reducing setup variation.

Which chipbreaker should be selected for mixed operations?
A single-sided chipbreaker, as provided, offers good chip control across facing and external turning; choice of chipbreaker should be aligned with workpiece material, cutting speed and machine stability.

Is the insert suitable for finishing passes?
Yes — with a 0.4 mm corner radius and robust PVD-coated substrate, the insert supports medium finishing operations while maintaining surface quality and edge life.

What ISO designation identifies this plate?
The plate is identified as DCMT070204 in the ISO indexable insert system and fits holders designed for the DCMT form and size.
