DCMT070204 AH6225 indexable turning insert — PVD-coated carbide, 55° geometry (Tungaloy)

The DCMT070204 AH6225 is an ISO-standard indexable turning insert designed for external and internal turning, optimised for stainless steels with a sharp, stable cutting edge and reliable chip control.

• PVD-coated carbide for improved wear resistance
• Universal grade for stainless steels AH6225
• Rhombic 07 geometry with 55° included angle
• 0.4 mm corner radius and one-sided chipbreaker

Longer tool life through a balanced PVD coating

The combination of a PVD-coated surface and a high-quality carbide substrate gives a measurable improvement in wear behaviour for medium-turning operations. The AH6225 grade is formulated as a universal solution for a range of rostfrei steels, providing a stable cutting edge that reduces flank wear and extends insert life. A PVD finish lowers the friction at the cutting interface and improves oxidation resistance, which translates into fewer indexings and lower tooling costs per part in production runs.

Precision geometry that improves process reliability

The rhombic 07 format with a 55° included angle and 7° clearance ensures predictable cutting forces and easy tool access in confined features. The 0.4 mm corner radius balances edge strength with profile fidelity, making it suitable for both finishing and light roughing where surface finish and dimensional control matter. The one-sided chipbreaker promotes consistent chip formation; explained simply, it shapes the chips to avoid entanglement and to facilitate safe evacuation from the cut, reducing the risk of tool interruption and machine downtime.

Seamless integration into ISO-based tool systems

As an ISO-standard insert, the component fits a wide range of established toolholders; the design includes a cylindrical hole with single-side countersink (40°–60°) for secure clamping and repeatable seating. The plate thickness of 2.38 mm and the 07 size make it compatible with standard external cutters and boring bars when the correct clamping kit and screw are used. This predictability shortens set-up times and supports consistent results across batches, improving throughput without compromising part quality.

FAQ

What materials is this insert best suited for?
The DCMT070204 AH6225 Tungaloy indexable turning insert (SKU 6829623-Tungaloy) is designed as a universal grade especially for stainless steels and performs well across a broad range of rostfrei materials.

Can this insert be used for internal and external turning?
Yes, the ISO-standard geometry and rhombic 07 form make the insert suitable for both external and internal turning tasks when paired with the appropriate holder.

How does the PVD coating affect performance?
The PVD-coated surface on the AH6225 grade reduces friction and improves oxidation resistance, which increases wear life and maintains a stable cutting edge under variable conditions.

What clamping arrangement is required for this insert?
The insert features a cylindrical hole with a single-side countersink (40°–60°) and is designed for secure clamping in standard ISO toolholders; correct screws and underlay must be used for reliable seating.

Which insert dimensions are critical for holder compatibility?
Key dimensions are the size 07, thickness 2.38 mm, 0.4 mm corner radius and the specified relief and included angles; these determine the matching holder geometry and tolerance class.
